In Early holocene Grimsvötn did a seriers of absoutley enormous basaltic Plinian tephra eruptions. If you take an average eruption, the response time would be three to ten days or so. The 2011 lake floor lavas was probaly erupted from sepparate fissures than the caldera wall eruption. There’s very little ash. Then it all ended, and the area has remained quiet ever since. A HUGE lava lake is apparently present in the “small” stratovolcano Mount Michael at Saunders Island. Im an enviromentalist and specialy intrested when the current modern fauna was at its most spectacular in Early Pleistocene. Once approved, further comments should appear without delay. People with underlying conditions, such as asthma, will have to take care of themselves. The current swarm sounds more intense. Eventually a dike forms, going either upwards or sideways. For the record, there is no danger of that happening if an eruption happens in Reykjanes—the peninsula tends to have effusive eruptions; mostly lava plumes but very little ash—and there are a few things we can safely predict about what an eruption in the area would look like. Lava is never going to go there. We need to know how much time we have in a lava flow crisis and that, of course, depends on where the lava comes up relative to populated areas or important infrastructure. But will history really be condemned to repeat itself? SISZ = South Iceland Seismic Zone. All the infrastructure is designed to withstand these kinds of quakes. Although there were people around, there was of course no one to take scientific notes, so the information is very sketchy. Grimsvötn has the largest supply and is the most active of these two. The most famous eruption on the peninsula dates from 1226 and occurred on the Reykjanes system This is the first eruption in Reykjanes since about 1200 AD, and is likely the start of a longer period (centuries) of new activity on the peninsula. And the sequence had just started from Brennisteinfjoll, towards Krisuvik. https://www.sciencedirect.com/science/article/abs/pii/0377027394900167 yet Saunders Island haves a polar climate.. the immense icesheet of antartica dominates the climate up to latitude 44 in some places of the sourthen ocean. A grand, continuously updated database of Iceland's main restaurants, clubs, cafes, shops, museums, tours and tourist attractions as well as a thorough events listing. It just took 22 trips to the summit of Hekla.”. both Grimsvötn and Katla has/have very large magma supplys and is both capable of very large basaltic eruptions. The map in the article seems to affirm this. Oh, I don’t hate people just for being people. This sentiment was echoed by Baldur Bergsson, a specialist in monitoring at the Icelandic Met Office, when the Grapevine tagged along with him to Reykjanes in July 2020. https://ui.adsabs.harvard.edu/abs/2006AGUFM.T41B1568S/abstract. It was part of a longer sequence of eruptions which left the tip of the peninsula a volcanic waste land. The Hreppar micro plate, North American Plate and the Eurasian plate meet there. It is undecided! Zooming out on the IMO page to view “north atlantic” shows a very wide spread shot gun pattern with peak at reykjanes. A camera drone sent to the lakefloor is needed to find the 2011 s rapidly emplaced lake floor lavas. There are probably some pretty good deals for real estate in Grindavik now. Research has shown that the number of children depends on the level of education of the women (not the men!). From taking a brief look it seems that activity has been increasing. The swarm is quite intense, 11 earthquakes M 4.0-4.1 in the last 3 days, and seemingly hundreds above M3 for the same period. How dangerous is Grimsvotn? The most famous eruption on the peninsula dates from 1226 and occurred on the Reykjanes system, or a few kilometers out to sea. Especially when volcanoes, when they actually kick in, then they switch gears and everything is happening one-two-three. Then in 1784, a sequence of large earthquakes happened in SISZ across South Iceland, and then a large rifting events, which nearly terminated as a fissure eruption, occurred in Hengill, in 1789. I think that the Mayotte eruption should also be considered a monogenetic volcano. This is part of the rift zone that is Reykjanes peninsula. Irpsit, about your last remark, EVZ and WVZ could, I think is, affecting each others activity. Or will a dike develop taking the magma southwest? Lots of melting in the caldera ice – shelf because of increased geothermal heat these days. He points out that studying the weather began centuries ago, but that the first weather map wasn’t published until the late 19th century.

Magnitude:4.22 When we know that, we start to think about ‘OK, what measures do we need to put in place to make sure that people are safe? Why this progressive, sequential pattern? Looking at CSM and GFUM graph for Grímsvötn its refilled soon. Another thing to bear in mind is the massive timescales we’re dealing with when it comes to volcanoes. Or this: Contrasting volcanism in the Michoacan-Guanajuato Volcanic field, central Mexico: shield volcanoes vs cinder cones Since the field is monogenetic, we shouldn’t expect Parícutin to erupt again. https://www.visir.is/g/2020200209908/telur-innskot-kviku-liklegra-en-eldgos-a-reykjanesskaga. Several fissure eruptions follow. forgets everything The subglacial lake is also permanently higher in water levels after 2011 This really is a great website, for where else would you get such informative up-to-date interpretative volcanic science and history all of which in a style open to all? Time will tell. “For populated areas around the region where a possible eruption could occur, we do not need to worry [about gas] in particular,” Kristín told us. Instead a new cone will form. This was just around the time that Edlgja erupted, so something might have happened tectonically-wise, across Iceland, that triggered that. Lava flows from an eruption of a volcano on the Reykjanes Peninsula in southwestern Iceland on Monday, March 29, 2021. It seems that the earliest eruptions, shortly after the ice went, were larger than they are now. This word is normally used for the year after an eruption, and indicates the effect of the volcanic ash rather than the ash fall itself. Givning the total volume of near If you enjoy our content and want to help the Grapevine’s journalists do things like eat and pay rent, please consider joining our High Five Club. Europe and America and Asia should be full of Elephants, lions, mammoths, giant deer, giant bears, cave lions, cave hyenas, cave bears, bison, hippos, sloths, cheetahs, leopards, ancient cattle, and predatory flightless birds. dont worry . The best way to do that is by improving education. It is far from any habitation so is not particularly dangerous, as volcanoes go. That may take some time (hours, typically). Also interesting is the fact that the very large eruption at Langjokull erupted around that time too. I think satellite measurements, in the end, might be the key to reliable eruption predictions, just like they’ve been the key to reliable weather forecasts.”. However, even in those cases we would have time to respond. “Putting an instrument on the ground, waiting a minute and a half, picking it up and walking ten steps, and doing it again. But on the peninsula the volcanic activity runs at an angle to the fault. I hope the farmland in the area is insured…. 2020-02-03 06:37:10 UTC Was there a bit of noise leading up to the 2,9, and does it mean anything? Despite this, little-explored places such as Geldingadalur have had a large impact on the history and culture of the Reykjanes Peninsula. DOST-PHIVOLCS reminds the public that sudden steam-driven and even weak phreatomagmatic explosions, volcanic earthquakes, ashfall, and lethal volcanic gas expulsions can still occur and threaten areas within Taal Volcano Island and nearby lakeshores. . We’ll just have to take it one day at a time.”, “For an average eruption of an average duration, the level of pollution could [become] uncomfortable for people,” Þorvaldur told the Grapevine. Over the past decades there have been episodes of unrest, perhaps starting with an inflation event at Hengil in the 1990’s. That’s why we want to learn as much as we can from each event. The peninsula has permeable rock, where sea water can get in. That’s the important thing. Great information, thanks Albert. If magma takes this route, it stays underground. It is enough to bury Reykjavik (a very spread-out city) under 10 meters of lava. The science of earthquakes and volcanoes is normally a quiet affair, some might even say repetitive, the vast majority of the time. A 0,2 km3 yearly supply for Grimsvötn fits perfectly to resupply 2011 s 1,7 km3 in around 10 years. Very well written and informative. The East Volcanic Zone is the prime suspect for any eruption, and with good reason: it is responsible for 51 km3 of this lava. Im not a fan of our dangerous civilization. The current inflation shows that magma is now accumulating, something that had not been seen here before. Grimsvötn is one of the largest basaltic volcanoes in the world and has on avarge the fastest and most ferocious basalt eruptions: at least on a human lifespann and scale. The vent that has been feeding the eruption since 2018 is independent and has been observed to get magma directly from the mantle, its magma source is 30 km deep so it would be considered a nice example of a monogenetic volcano. We are currently on a 5C track but the assumption is that people are coming to their senses. Dellenite, My issues with anthropogenic climate change lie in the fact that there so much overhype with some of these issues. I particularly like the “Iceland in Faults” diagram; that has escaped my trawling over the years and explains much very nicely. Lack of rain? Within this series there was one particularly violent eruption: after this explosion in 1226, the southwesterly wind spread 0.1 km3 of tephra across the area, with a thickness of almost 1 cm as far as Reykjavik. One thought; If the progression of activity from east to west is due to spreading (what else could it be) then the first rifting in the eastern parts, wouldn’t the rifting relax the more westernly parts and rather delay more rifting? Just like with COVID-19, as soon as we know something we give that information to the public. No, not yet. The Taal Volcano Network recorded two hundred twenty-three (223) volcanic earthquakes including eight (8) low-frequency events and one (1) harmonic tremor that lasted nearly three minutes long. The masses have always been selfish, around 89,000 children have starved to death due to a war and not natural causes but my fellow Americans still think that some celebrities minor family debacles is somehow more pressing then the death of innocent children. I am neither vegan nor vegetarian. You already believe people are doing what makes sense to someone with misanthropist point of view. Note: Hreppar is bounded by SISZ, WVZ, EVZ (includes the Dead Zone), MIB. It depends on the wind. Where would be the best place to see that data on a map? It objects to having too many links in a comment – makes it look like spam and it loves spam (poor thing). Is that true ? TFZ = Tjörnes Fracture Zone. At this point, all we have are best estimates. The second earthquake has 2 automatic locations which I guess will be corrected later. Good read. Coincidentally it is the same year Paricutín started to form. Thats the natural fauna of Europe and America and Northen Hemisphere. You might see some fractures in some buildings, but total collapse of buildings is not something we expect to see. Volcanic production keeps pace with extension and subsidence to fill the rift. That sequence in the Reykjanes, is it known to affect the activity in for example the EVZ? So if we model the system of the magma flowing, it is not going to reach the populated areas and it’s not going to reach the roads. On the peninsula, it is a bit of both. “We have good modelling and we know what we’re dealing with. We’d like to be able to have such exercises every day, but it’s not possible, because nature doesn’t work on that timescale.”. We’re quite used to dealing with situations like this. I don’t let personal feelings about people decide how I feel about the people I see and hear from. Iceland is one of the worlds most powerful magma sources and coud be the most powerful oceanic one. The up component will be off, but I suspect that if you remove the general uplift due to melting glaciers it too would be at a similar place as before the 2011 event. I could refer you to our Eldgja series for a discussion on the ‘fires’. SH = South Iceland flank zone. Thorbjorn would be the name of a hill, the corresponding volcano is Svartsengi which is active. On the EVZ, eruptions form long fissures along the spreading fault. Asia is showing how it can be done. the fissure arose a gray column of smoke, without force, depositing a fine gray dust.”. In the same Reykjavík Newscast where we spoke with Kristín, Rögnvaldur was optimistic. That’s even more right under Grindavík City, if I’m correct? While all of Iceland is geologically active, this is a story about Reykjanes, whose name literally means “smoking peninsula”, if that gives you any indication of just how active the area is. It’s also possible that the magma currently moving under the surface of the Earth has retreated, or that it’s still moving but hasn’t breached the surface yet. There’s been quite bit of activity in the last couple of years, but volcanoes are like cats – they do what they want, when they want, and they know how to get your attention. So its a volcanic system that has been mostly inactive in Holocene. Comet Swift Tuttle will fix us soon .. “Earth sciences in general and volcanology in particular have been struggling to get funding over the last five years. In the early morning hours of February 23rd, a 4.3 magnitude quake 7km beneath the surface and 3.6km east of Fagradalsfjall struck. But look closer. An informed and very easy to read explanation. Þorvaldur cited the eruption of Öræfajökull, describing it as a very explosive eruption. Saunders Island. Indeed Hafnarfjörður area haves a lava flow from the Krýsuvík system. There is also Waiowa,a remote maar in Papua Nueva Guinea that erupted in 1943. Over time, the eruptions became smaller. “It’s essentially cracks opening and the magma coming up. You truly don’t want to be without heat here in the wintertime. Hobbes After manual review they are all centered over Grímsvötn. The ongoing seismic event in Iceland tells a tale of upcoming eruption lasting for decades! Surgery might be a new volcano system, not monogenetic. So its easy to intensely dislike In fact, between 1210 and 1240, some 50 square kilometres of this region was covered in lava. I guess its very small … No other nation in the world has build its capital so close to so much young lava. Note:I am an amateur only. Distance From:7km S of Volcano, Hawaii. As a general point, if your comment does not immediately appear, it has probably been put in the dungeon by our system and needs to be approved by one of the admins. “What we try to do in the field of volcanology is a similar thing; to be able to forecast eruptions,” he says. Based on the preceding two events we can expect the eruption to last for several years to a decade, be mostly strombolian-to-vulcanian, and attain a cumulative VEI of 3 to 4. There is also an option to search their catalogue: http://www2.ssn.unam.mx:8080/catalogo/. if black outlines are missing around the dots it means the quake location is preliminary and unchecked. But I do know that half our impact comes from cattle. The ongoing seismic event in Iceland tells a … Even then, you would have boats to get everyone out.”. The last time the Reykjanes Peninsula was active was during a series of eruptions, roughly in the 950-1240 year period. We get very few events that we can actually observe. Cannot wait until Homo – Stupidus ges extinct! http://volcano.si.edu/volcano.cfm?vn=341060 Reykjanes Penninsula is 100 kilometers long from Hengill. Is there any structral analysis on the magma body of the Michoacan-Guanajuato Volcanic Field? This popup should only show once, but if it keeps showing let me know via email above and I will see what’s up. then it woud be a hawaiian – style lava fountain 4000 meters tall emerging from the caldera wall. Finally, interesting enough, research seems to show that there is a correlation with a general lack of activity under Vatnajokull when Reykjanes peninsula is active. Volcanic tremor has appeared recently as well, indicating that magma movements underneath are likely accompanying and/or causing the seismic swarm. Jesper (and other commenters): the spam deamon ate this. The good news is there’s little to worry about. Iceland has four major volcanic zones surrounding an hypothetic hotspot: the Reykjanes … But 30 times larger than that! Around this time, Icelandic sagas mention ‘fires in the sea’ at the Reykjanes Peninsula for 1223 and again 1225-1227 (which may or may not have been one continuous eruption). RPTZ = Reykjanes Peninsula trans-tensional zone. Reykjanes volcano eruptions: 1211, 1226 Typical eruption style: effusive (lava flows) Last nearby quakes. Recently, Burkard was in Iceland for work when a volcano erupted in the Geldingadalur region of the Reykjanes Peninsula, giving him a once-in-a-lifetime opportunity to witness history — and earth — in the making. Food was my reason for visiting this area: the lobster bisque in a small cafe in Grindavik (Cafe Bryggjan) is awesome. “Hekla erupts very often. I have been in touch with the developers, and they are aware of the issue however, they have suggested turning off the social plugin that allows you to log in via Google/facebook/Twitter/Wordpress accounts. A = Arnarvatn fault zone. “In Reykjanes, it’s quite different, because we know from the history of eruptions here that most of those eruptions are fairly moderate in size, and they’re mostly effusive, or lava-producing, eruptions. Necessary cookies are absolutely essential for the website to function properly. Whats the threat of lava to Reykjavik? The part of your article stating the sequence from the east to the west, over several millenia, is just brilliant, and a fact that I wasnt aware of, but I had that suspicion before. The eruptions may belong to the Reykjanes Fault System, they don’t use this fault for their progression. If the entire world would use renewable energy that would still hurt the enviroment and the idea that somehow all of this is going to change through some taxes and restrictions on the common people’s resources is going to fix global warming is almost comical but for some reason that is the exactly the type of action is what alot of media and people are pushing for. “They’re a consequence of a stress build up in the crust. The area around Grindavik showing the alignments of the volcanic system. Unlike Parícutin, Surtsey is knee-deep in water. We recommend though to listen to the professionals. Seismometer Monitoring Station WILD. After 1150 eruptions began further west, in Krisuvik, also lasting until about 1200. Fun fact: in September 1977, during the Krafla fires event in NE Iceland, magma entered the reservoir feeding the country’s first geothermal power plant. Magma is a lazy substance, and it will always follow the path of least resistance. You can also check out our shop, loaded with books, apparel and other cool merch, that you can buy and have delivered right to your door. Iceland is riddled with faults. If the Smithsonian is taken to be gospel, the repose periods have been getting shorter In this map, black lines indicate volcanic zones, and red are non-volcanic faults. In a nutshell, we use the worst case scenario to make sure we have the right response to ensure everyone’s safety.”. (PDF download direct link). Our on-line world may finally make it possible. Whats is the current 2020 Note: Due to the effect the Coronavirus is having on tourism in Iceland, it’s become increasingly difficult for the Grapevine to survive. Just a friendly correction to help you improve your writing . DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately communicated to all stakeholders. They have both sideways (lateral) motion and spreading (extension). Speaking of Hawaii, apparently Mauna Loa has been rumbling a fair bit recently again. It’s not very nice. That is 3C this century, with 70 cm of sea level rise. Eyjafjallajökull is still fresh in people’s minds, a volcano which erupted and began to spew a gigantic ash cloud into the atmosphere in March 2010, crippling air traffic across the European continent. As a system it is a very young volcano. Farming and volcanoes make for an uneasy partnership. Suggesting 1 km3 of lava was also rapidly emplaced on the deep lake floor. Very intersting read! Most of the volcanic system is covered by Holocene lavas and eruptions have occurred in historical time during the 13th century at several locations on the NE-SW-trending fissure system. That’s just the nature of the science of earthquakes and volcanoes. This was followed seconds later by a 5.7 quake near Keilir. It seems the swarm may just be restarting. This map contains the final, manually verified, locations: http://hraun.vedur.is/ja/viku/2011/vika_20/index.html, Tomas Andersson thank you It causes mortality in the farm animals, and famine. Once it hits the magma sills, even after 700 years, it gets heated and moves up. ÖS = Öræfajökull–Snæfell flank zone. I love impact events as much as the next guy but I’d prefer the geological extinction or a cosmic cause. “But that’s science. Reducing our population would also be helpful but of course takes much longer. H = Hofsjökull volcanic system. The bank in January may have created a crater of 200 meter across, in my quick estimation. Along the way, the first thing you notice are the immense lava fields which stretch all the way to the horizon. It is better to limit links in a comment to no more than two – admin, http://wheneuropewasanocean.blogspot.com/2015/11/exploring-natural-land-cover-of-europe.html, http://wheneuropewasanocean.blogspot.com/2015/10/lands-pristine-europe-during-eemian.html, http://wheneuropewasanocean.blogspot.com/2015/10/a-world-in-tar-pits-california-before.html, http://wheneuropewasanocean.blogspot.com/2015/11/elephants-of-antiquity.html, http://wheneuropewasanocean.blogspot.com/2015/09/the-early-holocene-of-europe-from-11000.html, http://wheneuropewasanocean.blogspot.com/2016/06/accepting-consequences.html, http://wheneuropewasanocean.blogspot.com/2015/10/big-cats-of-europe-past-and-present.html, http://wheneuropewasanocean.blogspot.com/2015/09/alien-species-and-future-ecology-of.html, Very good links to get a view on the natural enviroment of the current geological age IF humans never evolved. Thorbjörn volcano (Reykjanes Peninsula, Iceland): volcanic unrest continues with new inflation and earthquakes. If that is so, the question is: what triggered the start of a sequence. Fagradalsfjall volcano has no document eruption history over the last 10.000 years and the main volcano location is unknown if it exists. Of course, we can’t rule out that we would have a megaeruption on the peninsula, but that’s very, very unlikely. Must have been some exiting (maybe too exiting) last two weeks for the population of Grindavík! But is not included the RPTZ…. Please do not be alarmed, this is a planned change and it doesnt mean we’ve been hacked! A small update: inflation at Þorbjörn is up to 5 cm. Whats the chance of lava invasion in the city? It is about a year off, I think. We are planning to come back to Grimsvotn soon! I called to my husband. As the land rebounded from the ice age 14000 yars ago, it may have generated more magma. The 1226 eruption was part of this group. There have also been 2 very weird-looking earthquakes from Mauna Loa. This shows the effect of the mantle heat underneath the Vatnajokul which increases the magma production there. It is the direction of the spreading rift. Rögnvaldur Ólafsson, spokesperson for the Department of Civil Protection and Emergency Management, is a part of the team that would be key to these evacuations. But they did not fade quietly into the volcanic night: The thickest tephra layer dates from 6100 BP, up to 1.5 meters thick. “In terms of danger to the population, let’s just make an assumption that we have an eruption site where if lava comes up it will flow towards a populated area,” he says. Volcanoes on the Reykjanes peninsula go into this stage of unrest and eruption every 800 years or so, and that period can last some 200 to 400 years. If history repeats itself, the real eruptions won’t begin here. DOST-PHIVOLCS recommends that entry into the Taal Volcano Island as well as into areas over Taal Lake and communities west of the island within a seven (7) km radius from the Main Crater must be strictly prohibited. If you face disaster from several things, you have to deal with all of them. Now the Svartsengi and Reykjanes systems joined in with a series of eruptions, from 1211 to 1240. To Rögnvaldur, this is all a part of the job. But where would these people go? People can’t see beyond the end of their nose in that case, Blaming, finger pointing, gaslighting, virtue signaling and assumed moral superiority without accepting personal responsibility is also a typical human behavior…. The topography of Reykjanes Peninsula was formed by glaciers and volcanism, basaltic lava fields covering a good part of the peninsula, in between volcanoes of subglacial as well as subaerial origin, namely tuyas, hyaloclastic ridges (tindars), shield volcanoes and crater rows. Reply to: Reykjanes Volcanic activity. And if you know Spanish, there is quite a body of literature when searching for “michoacan guanajuato campo volcanico magma” in Google Scholar. Iceland is currently experiencing a magnificent eruption on the Reykjanes Peninsula, the land that connects Reykjavik with Keflavik International Airport.In the weeks before its eruption, the capital and its surrounding areas had been shaken by tens of thousands of earthquakes, an ominous promise that volcanic activity was imminent. So at the moment it is not heading for an eruption. Latest satellite images. Type of lava? Of the missing amount, 8 km3 is hiding in clear sight to the west of Langjökull, in the Western Volcanic Zone. As a result, it wasn’t studied from birth to end as crucial early events such as the initial formation of the eruptive vent took place out of sight underwater. So our assessment in that case is, if you suspect there’s an eruption imminent, you evacuate the whole place and get everyone to safety. Like an extremely violent lava spray. The blue lines indicate volcanic flank zones, with some minor rifting, where stratovolcanoes have developed. Even with all of our advanced technology, knowing when a volcano may erupt is still not exactly pinpoint accurate. However, in 1783 Laki erupted. https://www.carleton.edu/departments/geol/Resources/comps/CompsPDFfiles/2009/coxt_2009.pdf. If you’re a misanthrope then why would global warming bother you? “It has to be an integrated thing. But knowing Grimsvötn have the largest magma supply in entire Iceland… it Probaly is the volcano with the largest eruptive capability in Iceland. AI might do it though. We'll assume you're ok with this, but you can opt-out if you wish. In this region, eruptions move from the east to the west over several hundred years, terminate, followed by 700 years of volcanic sleep before it restarts. Things are cooling down. Its eruptions are connected to the WVZ, not the Reykjanes Fault System.). Here, we examine a timeline that begins on February 23rd, when a series of significant earthquakes began to ripple through the area, culminating in the first signs, on March 3rd, that a volcanic eruption may be on the way. Talking about the moment when Paricutín was formed, this is the account of Paula Pulido who witnessed the event: “About 4 p. m., after talking to my husband, I heard a kind of loud whistle, New Video from USGS – What’s happening at Kīlauea Volcano’s summit? The ONLY volcano that could be studied from birth to end? Here the bend in the fault gives a larger spreading component. Ash and tephra are unhealthy for cattle when digested with the gras they cover. It might have been its first eruption.
