reykjanes volcano map

 

5. The Reykjanes volcanic system is the westernmost of a series of four closely-spaced fissure systems that extend diagonally across the Reykjanes Peninsula. The red lines indicate the tectonic plate boundary, where earthquakes are common. One of our local Icelanders will be along to correct me if I’m wrong, but I think “litli” is an inflection of the Icelandic word for “little”, and “hrùtur” is, iirc, either singular or plural for “ram(s)”. “Below are two different presentations of the same Q-lava+FlowGo model run, showing the most likely flow path of the lava from the new fissure. Will this be a first for Iceland if the eruption start is caught on a dedicated webcam? In the past 24-hour period, the Taal Volcano Network recorded forty-two (42) episodes of volcanic tremor having durations of one (1) to seven (7) minutes and low-level background volcanic tremor that began at 6:37 PM on 10 March 2021 and lasted approximately four and a half (4.5) hours. The map shows the approximate location of the new fissure. Look further down for an illustration comparing the surface features above a dike intrusion vs a sill intrusion. The magma counters the sinking but is not enough and perhaps too deep to counter the central sinking. But just when it was ready to break through, Geldingadalir beat it to it and stole its fuel.. Thank you both, I’ve really learned something and have been helped to think geologically. Hide HELP HOW THIS SITE WORKS. New post is up. Look up most recent and past earthquakes on the Reykjanes Peninsula, Iceland. There’s no snow in that picture – when was it taken? This page, and the info accessible via it, might be useful: http://icelandicvolcanos.is/, And this zoomable map has been one of my favourites for years: http://jardfraedikort.is/index_enska.html. m^3/sec I have felt earthquakes several time before in this country and I have never been scared of them. Arnarsetur is a short monogenetic volcanic fissure with scoria and spatter craters, formed in an eruption that was an integral part of the Reykjanes Fires, a volcano-tectonic episode from 1210 to 1240. I’m trying to find that study that associated (it seems to me) underwater eruptions in Reykjanes shortly after the Lakagigar eruption with this rifting process. It is like watching the landscape through a Mag 9 earthquake. rúv has changed the postition of their webcam, is it pointing now to Nátthagi valley? (desc./asc. More impressive was a couple of years ago, exploring a route into Stora Hamragil. I am still waiting for a video where you actually see the ground cracking and opening. If the lake drains first, the loss of mass on top of the caldera can trigger the eruption, but this is not certain. Bardarbunga wont blow up, if you are meaning that. In particular, they are in no way directly coupled with what’s currently happening at Reykjanes. The other two parts of the dyke show quake activity because the magma from the intrusion is just sitting there getting cold. is most likely to come along the blue region, not necessarily in the centre though. Hide map webcam locations. The fissure is two kilometers in length and the lava formations that originate from it cover 20 square kilometers. Today is an anniversary not even Iceland can make us forget. The valley was largely filled with lava but the edges were not rising very fast. But if so, why has the ground either side risen relative to the wider area? (Perhaps the conduit began melting its surrounding rock deep down/upstream of the dyke feeding the old site, and this process found a new route to a separate dyke?). The lake inside the caldera is also at a high level and ready for a draining event. If it happens at night though, I guess the IR cameras dynamic range will not cope with a super-bright heated thing appearing on a relatively cold background. I add, and it is my personal hypothesis, that once in place of the lake that currently occupies the Grimsvotn crater, there could have been a lava lake later defined, perhaps during the Lakagigar eruptions as happened at Ambrym in 2018. – Something I am struggling to get my head around: If there was a blockage of the conduit/dyke, causing a reduced flow from the old site and increased pressure leading to the new eruption, surely we would have seen a reduced flow but with higher pressure before the new fissure opened up (ie. At the end the camera changes to a view of the new fissure being born. All 3 of these 3+ EQ’s in the same area this morning. WOW! The Reykjanes volcanic system at the SW tip of the Reykjanes Peninsula, where the Mid-Atlantic Ridge rises above sea level, comprises a broad area of postglacial basaltic crater rows and small shield volcanoes. The most seismic activity was in Reykjanes peninsula where around 1000 earthquakes were detected. The flow out of the twin cones is restricted by the width of the conduit below, perhaps 100-500 meters depth. near Fagradalsfjall. hraun.vedur.is/ja/drumplot/drumplot/grv_highpass_2.0.png. !”, East and Vertical ground displacements in the ongoing volcano-tectonic crisis southwest of Reykjavík, dominated by strong left-lateral shear and symmetric vertical displacements over the NE-oriented opening. I think this is bigger than the other flows were, just look how the lava tumbles out of the upper cones of the new rift. Just make sure the boat doesn’t capsize while going down the rapids…, Another drone video. Some years ago i was walking in Spain on a old seabed. Sooon Reykjanes may erupt … The surface flows now stay close to the cones. She said that a team conducted by Asta Rut Jjartardottir was looking into the happenings in the area. Eruption risk is lower for now in that volcano. / | List https://www.mbl.is/frettir/innlent/2021/04/05/hrauntaumar_flaeda_a_gossvaedinu/. Is there a chance this will flow into geldingadalir? We’ll see how much of a spectacle the new cones can provide in their place. 427 (Suðurstrandarvegur) and is around 2.2 miles to the volcanic activity. It wont be anything gigantic if it derives from Bardarbunga itself, which has a deep caldera and just fed Holuhraun, but Hamarinn could be a different story. New cam https://www.ruv.is/sjonvarp/beint/ruv2?fbclid=IwAR1v-dHuJdD5yfMpR1xcDDABVAYbh_gEZ-URumdUN_eCddxVkQI_cZNrf3o. Rocks of normal magnetization of … Let’s GO! Superb, isn’t it. You think they aren’t already dry? Hopefull she will respond, as I sent email asking the geographical location and the camera pointing angle of that picture. What are the elevation of the 2 sites ? It is looking to be a real competition between Iceland and Hawaii this year, as well as Etna. But this is more like a constriction halfway in the hose. Any horse breading geologists out there? Choose your volcano destination! If I am wrong freely I correct myself. https://comet.nerc.ac.uk/tag/volcanic-deformation/, good morning and a beautiful view from the Rúv webcam, https://www.ruv.is/frett/2021/03/03/beint-vefstreymi-af-skjalftasvaedinu-vogastapi, Perhaps they just pretend. They are however independent processes and would have happened anyway. Jesus! The last eruption on the Reykjanes Peninsular was some 800 years ago. Or towards the cam? Average flow and … Dredging operations resulted in recovery of basaltic … Also, it is interesting that it is a possibility that these fissures, if they continue to erupt, may add lava to Geldingadalir.”, Nice maps, but the fissures should be on the upper plane, north of the red arrow. I am not saying that Bardarbunga is a supervolcano, it is absurd to even think so. If it continues, the fissure could extend further towards the valley, purely because that would be a shorter way to travel for the magma. The Reykjanes volcanic system at the SW tip of the Reykjanes Peninsula, where the Mid-Atlantic Ridge rises above sea level, comprises a broad area of postglacial basaltic crater rows and small shield volcanoes. One of the wonderful things about Icelandic is that a lot of (?most) placenames are toponyms, and sometimes commemorate people and/or memorable incidents. It was taken on camera indeed, but while it was something special, the video only shows a bright spot over a black background. The way activity moves around there seems to be no boundary between the so called “systems”, and more like the entire rift zone acting as one? See the diagram in Bjarki’s post at the top. (Update 2: the extended fissure is beyond the gully, as pointed out by Reykvolc. DOST-PHIVOLCS reminds the public that at Alert Level 2, sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within the Taal Volcano Island (TVI). And wouldn’t we expect the ground to be rising at the dike owing to pressure from beneath? It would be quite a sight, particularly during the night. Remember that beautiful Vimo footage of EJ shot through the derelict fuselage of a DC3, the footage that spawned 10000 new young and old volcanoholics. The next pulse should be starting soon. Volcanoes & Earthquakes; Zoo; See All Cameras ; Most Viewed Cams; Map; Most Viewed; Latest; All Cams; Georgia State Cams . Grímsvötn and Bárðarbunga are too far away from Reykjanes. Features here tend to erupt only once. Just watched the mbl cam and the south cone had a collapse afain, although it quickly recovered. – No/little chance then that this is the result of an increased supply from depth then? Right back since 2010 on Jon Frímann blog the build up has been great reading and addictive. Interestingly, the new fissure is along my speculated “warm” path. The main flow remains down the gully though. 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. I concentrated on it and realised that it was as though waves from beneath where I was sitting were shaking me, a bit like a marble on a tray. At 11:32 today UTC), weak earthquakes occurred in the area. A monogenetic volcanic fissure (2 km) with scoria and spatter craters, rugged lava formations (20 sq. Remember how when the dike was first being created that it had a supply rate of about 20 m3/s, but effusion rate at the vent was never really close to that, the new fissure is bringing it up to about that now. A great tribute to the map-maker’s craft. I think the start of one was caught on a traffic cam or something, a vague recollection. That was meant to be a reply to Albert at 12.12 and Tomas at 13.32. It is located 1 km northeast of the twin peaks. Today, 11/3 at 08:53 an M4.6 was detected around 6 km W of Grindavík PPS this may have triggered the Dugeon Troll to be extra vigilant, which will require us to manually release… please be patient, https://www.mbl.is/frettir/innlent/2021/03/10/fleiri_skjalftar_en_allt_sidasta_ar/, https://ui.adsabs.harvard.edu/abs/2009AGUFM.V24B, https://twitter.com/Vedurstofan/status/1369615356466233347, https://www.icelandreview.com/nature-travel/ongoing-risk-of-eruption-on-reykjanes-peninsula/#:~:text=Today%2C%20the%20Icelandic%20Met%20Office,in%20the%20years%202014%2D2019, https://twitter.com/EIlyinskaya/status/1369760684632911872, https://www.emsc-csem.org/Earthquake/earthquake.php?id=957800#map, https://twitter.com/Sjonni_KAUST/status/1369884714924920832, https://twitter.com/Vedurstofan/status/1369955408195039240, http://jardfraedikort.is/index_enska.html, https://twitter.com/TheWatchers_/status/1369997668206841856, https://twitter.com/Vedurstofan/status/1370051487401906177, https://twitter.com/krjonsdottir/status/1369761147826692106/photo/1. Perhaps the new fissure is extending to the northeast of the gulley? That strange void in the middle also makes me wonder. I know it’s pure coincidence but I still can’t believe I got the quake I asked for and neither could my co-workers the next day. Thank you Albert! I was reading long ago that eruptions in the Reykjanes peninsula occurred around that time. The map shows the Geldingadalir flow, as it was expected to develop. And with a bit of luck, this time it might become real . Looking at the verified quakes map since March-29th is interesting (this map is not posted in the English version of IMO website) https://skjalftalisa.vedur.is/#/page/map seems to show the fissure extent underground from the Gendingdalir location clear to Keilar as delineated by the quake swarms. It seems it is getting back its strenght. When I was about to sleep I felt the house shaking. Vibration from wind or earthquake should almost react the same way…, https://en.wikipedia.org/wiki/Earthquake_engineering. DOST-PHIVOLCS strongly recommends that entry into TVI, Taal’s Permanent Danger Zone or PDZ, especially the vicinities of the Main Crater and the Daang Kastila fissure, must remain strictly prohibited. From there the lava stream turns left onto the slide leading down to Marrakesh (no wait, it’s Meraldalir), towards the magic pond…. My guess is that the twin cones are down compared to the past. Looking at the picture here, does this not show a rift along side Reykjanes? Or am I just imagining stuff from watching the cams for waaaaay to long?! Over 1700 earthquakes have been measured in the Reykjanes Peninsula since midnight, few of which were over M3, the largest one measured M4,6 at 08:53 GMT this morning. I speculated that the silent part of the dyke was silent because it is the transport path between the point where the dyke is fed from the mantle and the eruption site. You can hear a loud roar or rumble (something like the Balrog from Lord of the rings coming from the underworld) followed by wave like 3 seconds later. It is a little bit of rifting. This morning saw me scuttling to the loo next door in a horizontal snow blizzard. https://www.phivolcs.dost.gov.ph/index.php/volcano-hazard/volcano-bulletin2/taal-volcano/11434-taal-volcano-bulletin-11-march-2021-08-00-a-m. I wish they’d pull back on the zoom a bit. It was the 4.5. Couple of questions/thoughts though if I may? There are two possibilities. This area seems to have the furthest WSW 3+ activity so far. If the intrusion continues along the current line it will end up behind the camera. I usually post the first type but now for a change, I am posting this outstanding drone video. The long awaited lava falls are here already. My dog get crazy and run away. The submarine Reykjanes Ridge volcanic zone is contiguous but is considered only for a small part integrated into the Reykjanes volcanic system, which is the westernmost volcanic system closely spaced en-echelon fissure systems extending across the Reykjanes Peninsula. But I have to admit that these two weeks have made me a little uncomfortable. So, if the drones stay below a certain altitude they would be restricted only from the immediate vicinity of the airport and perhaps a bit further when aligned with active approach corridors. The new vent got the last push it needed to erupt. That would suggest that the new eruption is likely to cannibalize the old one. And thanks eccentricviewer for explaining! But why? The controlled airspace around an airport is typically shaped like an upside-down wedding cake, with the bottom tier having the smallest radius. If it continues it would eventually flow towards Geldingadalir. On checking later, it emerged that it had been an M3.1, 1km depth and about 3 km from where I’d been sitting. how long it spend in the dike is not known, but there was no indication that the magma was aging during the eruption. The activity there remains notably weak. The eruption was an integral part of Reykjanes Fires, a volcano-tectonic episode in 1210-1240. This rank amateur has some questions as I try to understand the vertical displacement image. Thank you. If that gets smaller, less magma can be pushed through. They were very entertaining during their prime. I bumped into someone a bit later who’d also been enjoying the view, standing near about 2kms from where I’d been. or dragons?or the mother of the dragons is comming? There were also 84 quakes below magnitude 2.0 which people don't normally feel. – this magma found it easier to find a new route (potentially to an older dyke given the lack of earthquakes/tremor) – although the magma looked pretty primitive from the get-go so maybe it just exploited some major deformities from the tectonic quakes we’ve had in the region – to the surface as it was easier to do this than re-expand the pre-established conduit section, If only we had the technology to know exactly what was going on underground, would love to know exactly what was behind these changes – then again, that might just take away part of the fun ha! The accuracy is not guaranteed! Click on one of the locations on the map to view the feed. Is it possible to tell lava flows apart on it’s contents from different volcanic systems on the peninsula? Felt a bump in the night when I was camping near the eruption site of the Krafla Fires in 1980. Just below the small glacier on the far mountain. Once this eruption is over (whenever that will be), the next eruption will occur somewhere else on the peninsula and it will firget about this fissure. The flows from the two cones were notably weaker this morning. I really enjoy this blog. These parameters may indicate increased magmatic activity at shallow depths beneath the edifice. I live in an apartment building 3rd floor in Reykjavik. I think that the camera is also not level, making it look like it is running up hill. That’s the view you’re looking for .. We saw some lava simulations earlier here in the cafe. The map shows the Geldingadalir flow, as it was expected to develop. Thanks again Albert! https://www.mbl.is/frettir/innlent/2021/03/05/lodrett_kvika_liggur_a_2_km_dypi/, Around 800 quakes detected since midnight. That puts it along the dike, and this is clearly fed by magma in the dike. Grimsvotn will definitely erupt soon, but just like Kilauea in December it probably wont be obvious until maybe an hour before it happens, so im not waiting for it I think it will happen in very short succession after a jokullhlaup from its crater lake draining, which might happen quite soon. And comments about amazing photos and videos. About 30 of them were of M3.0 and above, largest one M5.1 at 3:14am. It is, however, an impressive sight to see this lava river flowing down into Meladali. from RUV https://www.ruv.is/frett/2021/03/18/eldgosid-i-geldingadolum-i-beinni-utsendingu?fbclid=IwAR1HjP9wEFNW2bLIaJQj5X96BK8NJsTadE35FC7d0OeEXDJtzzunerfxebg. I did wonder where it was all going… but was too busy to keep up until this evening. New cracks in the ground, does a topo exist showing their extent? As the dike progresses closer to the surface it will eventually form visible faults and a graben. Ha, that was a good April Fools joke! Y You may see this location on the map down the page. Notify me of follow-up comments by email. Very good explanation by Freysteinn Sigmundsson on Changed as requested. Late on March 19, an eruption officially began as lava broke through the surface near Fagradalsfjall, one of several shield volcanoes on the peninsula. But on the bottom right I see some glow creeping towards the camera. It was unlikely to make it at the current flow rate: it would likely solidify on the way. At 11:37 a stronger event happened. ?itok=zFkKPbua×tamp=1617646576. The map above shows the source of the volcanic eruption at Geldingadalur, close to Fagradalsfjall on the Reykjanes Peninsula. Looks like the dike turned slightly east as it progressed south. I’m looking forward to new measurements of the gasses and the type of lava and what’s in it. The highest of the system's multiple vents is 230 metres (754 ft). However seeing its still sharing its output with the Gelding vents. I thought: “Oh no, an earthquake! And suddenly, reports appeared of a new fissure which had opened. If you plot the earthquakes from November 2019, you will find that the previous swarms on the Reykjanes Peninsula have followed the same east – west pattern. So far we were always talking NNE to SSW rifts. Ground deformation parameters from electronic tilt, continuous GPS and InSAR data analysis indicated a very slow and steady inflation and expansion of the Taal region since after the January 2020 eruption. Civil aviation authorities must advise pilots to avoid flying close to the volcano as airborne ash and ballistic fragments from sudden explosions and wind-remobilized ash may pose hazards to aircraft. The earthquakes are still migrating further southward. Activity has gone up and down over the past week, but this was definitely a down. Snow-covered Sandfellshæd shield volcano (lower center), capped by a small crater, rises only 74 m above the Atlantic Ocean to the south. Watch this live HD webcam stream of the amazing Geldingadalir Volcano, its volcanic eruption started on 19 March 2021, nearly 800 years of dormancy, in the valley of Geldingadalir, near the mountain Fagradalsfjall on Reykjanes Peninsula, Iceland. Does quake swarms 4 or 5 days ago give a hint of new activity on the underground dyke It is hard to tell the viscosity when it is flowing through such a steep gully. Who knows what happens underground! I need to see some nice lava fountains and lots of happy official videographers fighting to show us their drone footage. He’d felt nothing – though he also subsequently disclosed to me that he was off his face on acid. A surprise indeed! There are two types of comments. I was in Amsterdam at the time. It turns out, the lava found a better way, underground. Activity at the Main Crater consisted of weak emission of steam-laden plumes from fumarolic vents that rose 5 meters high. Write in haste.. Then yes, I believe it will be the first. The Meteorological Office's nature conservation expert confirmed this to the news agency right now. As Thomas suggests, the new one may be closer to the vertical conduit. Albert, the new fissure is further west than you show. She says that they have examined and mapped a large part of the cracks that are now erupting and are wondering why magma is coming out of them now and not when it started to erupt in Geldingadalur. Around 2500 earthquakes detected in Reykjanes peninsula yesterday. Just to clarify, I was wondering if it was happening, because the screen on my phone is very small en zooming pixelated the image to much to be sure. Map by Isor . Krýsuvík volcano has quieted down a little in the last 24 hours. Thank you Albert of keeping us informed….. 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. That makes sense, thank you – I appreciate the response! He is referring to the uncertainty regarding whether an eruption can be expected soon on the Reykjanes peninsula, Southwest Iceland. We would recommend that you register for a Volcanocafe account (here) so that your details are saved and noone can steal your username etc. The rifting lets the centre sink and the pushes up the sides (the rock has to go somewhere). Amazing video Irpsit, thanks for sharing. Drone use is also now ubiquitous, so providing the weather plays ball, we may get some footage similar to the stunning stuff that captured the early stages of the 2018 Kilauea eruption? “There was an earthquake?” she replied, “oh, I just thought who in your house was running the washing machine in the middle of the night.” . It turns out it’s happeninf again today. Kind of like, “Ooo, thats an earthquake”. I think so. First you get a depression above the dike and uplift to the sides. The two 4.2 quakes I’ve experienced (Greece and the UK), both made a loud rumbling/roaring sound. I was watching when Bárðarbunga started. Thankfully the snow has melted but it’s still very cold. This has been added to the drawing.) Here, the dike has pushed the sides apart and the movement extends close to the surface. How will it evolve? Reykjanes volcano crater collapse. Volcanic activity is escalating in a region of Iceland that has not erupted for 800 years, with scientists warning it could cause disruption for centuries to come..
