! Dike intrusion started in Sundhnúksgígaröð.

The lightning detector in our garden in Reykjavík (Kópó) detected an impressive range of lightings today, with closest lightning only about 60 km away and the farthest over 9000 km away! @blitzortung.bsky.social

The M7.7 quake ruptured roughly 200 kilometers of Myanmar's Sagaing Fault. According to @judithgeology.bsky.social and @kyle-bradley.bsky.social, there's likely up to 5 meters of slip along the fault. This is a big one near some dense populations. More in their summary below:

Latest news from IMO. Svartsengi still inflating. Eruption likely in the coming days...

Discussion about the Nature paper on Öræfajökull: communities.springernature.com/posts/insigh...

Latest update from IMO about Svartsengi: Magma continues to accumulate, and its volume beneath Svartsengi has never been greater since the eruption sequence began in December 2023. The most likely scenario is an eruption in the area between Sundhnúkur and Stóra-Skógfell en.vedur.is/about-imo/ne...

Getting Plinian... Looking at eruptive styles within the Bishop Tuff today. This outcrop is from the Chalfant Quarry, north of Bishop. ⚒️

On the late evening of 15 March 2025, Strombolian activity started at the Southeast Crater on #Etna. Here are a few photos taken around midnight from the area of Piano Vetore, high on the southwest flank of the volcano.

I'm no interested in travelling there and many in my group have also cancelled their plan to attend AGU fall meeting this year.

We are still waiting for an eruption. Below the latest news from the Icelandic Met Office.

Apparantly not much news about the Jan Mayen Earthquake tonight. By mistake I posted old news before about Jan Mayen Earthquake which I have now deleted. Thanks @gongudottir.bsky.social

M6.6 Jan Mayen #Earthquake as recorded in Iceland. Note we have an experimental setup in Eldey island sw of Reykjanes peninsula which recorded the earthquake clearly. #vedurstofan

Development of magma accumulation & estimated total volume of magma beneath Svartsengi. The zero point is based on the state before land uplift began in late October 2023. The total volume of magma beneath Svartsengi is now greater than what had accumulated before last eruption on Nov20, 2024.

Arctic seaice extent may have peaked. This would be an extremely low maximum. Let's wait for NSIDC statement.

Paper out! This is one of the main and last outcomes of the IS-TREMOR project supported by the Iceland Research Fund. Shoutout to Jean for leading this work! @seismotom.bsky.social @cocaudron.bsky.social

Hello Sentinel-2C 👋🛰️ Images from the recently launched @esa.int third #Sentinel2 satellite are now available. Some winter wonderland images from #Iceland acquired yesterday over the Northeastern highlands. 📸 Lake Mývatn 📸 Jöklusá á Fjöllum glacier river 📸 Askja volcanic caldera & lake

If you're worried about aviation safety, these NOAA/NWS cuts are just as alarming as anything happening at FAA.

IMO's models suggest the volume of magma accumulated beneath Svartsengi has exceeded the amount present before the eruption that began on November 20, 2024. It is anticipated that an eruption may start in Sundhnúksgígaröð with very short warning. Below latest IMO news:

Map showing eruptive fissures on the Sundhnúks craterrow since 2023

On a short holiday in Lisbon. Beautiful city. Super happy with the 18°C & sun today ♡ I fear I will miss the onset of the next Reykjanes eruption although my colleagues are defininately on top of things back at the Iceland :) MetOffice!!!

The latest weekly Bulletin on the activity of #Etna is out, with lots of details, data and images! www.ct.ingv.it/joomlatools-...

The Lisbon quake magnitude is being set between 4.7-4.9, depending on the source. So far, no news of any damage nor injuries. Apparently no Tsunami warning as well, although I can't find any official source saying so. https://earthquake.usgs.gov/earthquakes/eventpage/us7000pe8k/executive

In my way to Lisbon...

Nice to observe that the M2.8 earthquake that occurred this morning (the Hvalhnúksfault) was recorded on the DAS and is clearly seen in the raw data, also on the N-cable we just installed. The earthquake was felt in the capital region. en.vedur.is#quakes www.youtube.com/watch?v=LFQf...

Again: Live "waterfall" DAS-streaming. The unit is now set to record 2 fibers, from Keflavík to Reykjavík (left) and from Kef along the south coast to Þorlákshöfn (right). It is the first time we see what is going on along the fiber north of Svartsengi and Grindavík. Next eruption expected any day!

magmarising.org An art exhibition in Cambridge.. Sounds so much fun.. Wish I could go!!!

Distinguishing between tectonic and volcanic earthquake swarms can be tricky

#Etna #volcano (Sicily, Italy): outpouring lava flows - The effusive eruption at the volcano persists. The advancing lava flow continues to be active on the western-southwestern flank, emitting from the new vent at the southern base of the summit crater complex. It has extended approximately 2 k...

Hi Seismo-Bluesky! I decided to test a pipeline with SeisBench, PyOcto, NonLinLoc, and HypoDD on the Santorini sequence. The level of activity (>4,500 events) is truly stunning! There are repeated bursts migrating backwards and forwards, spreading outwards from a narrow, almost linear channel.

IMO is using fiber optic sensing (DAS) to monitor deformation related to volcanic unrest on Reykjanes Peninsula. It is a collaborative effort between Ljósleiðarinn, Reykjavik University, Caltech and University of Houston. Below a 'waterfall' plot of the raw data we are streaming (last 30 min).

Things to deal with after last week's red weather warning

Very excited to announce early public beta of our new website at The Icelandic Met Office. @maptiler.bsky.social plays a key role in delivering maps for the new site. The weather charts use their Engine + Cloud + Weather SDK with the front-end handled by our friends at #Origo -> gottvedur.is

It is time we move the seismometer out of the garage. My drumming sessions are killing other detections. (Me drumming from 12:40-14:10. Honduras M7.6 recorded shortly after 23:30)

The Icelandic Met Office has launched a beta version of a new website gottvedur.is/en/ For now it only contains weather info.

Our (Icelandic Met Office) latest news on the Reykjanes Peninsula. Magma accumulation beneath Svartsengi continues. We are expecting a new eruption in Sundhnúks crater row. en.vedur.is/about-imo/ne...
