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:

Discussion about the Nature paper on Öræfajökull:

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

New paper out!
Led by colleagues at Uppsala University.
Structure of Öræfajökull volcano revealed by data collected during intrusive activity 2016-2018.
Photograph of a student standing in front of a cliff like outcrop of tuff, layered for the first 2 meters, then massive and matrix-supported for the upper 3 meters. Some gravel is in the foreground and the sky is blue.
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.

By mistake I posted old news before about Jan Mayen Earthquake which I have now deleted. Thanks @gongudottir.bsky.social
Oh no... thanks!

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.

From vedur.is
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.

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!

Awesome to see that these plots are inspiring! The depth of the cable varies. The weather is affecting our observations like with normal seismometers, e.g. more yellow when windy. Note the data is unfiltered raw data. For our operational 24/7 volcano monitoring at IMO we have more advanced plots.

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.

If you're worried about aviation safety, these NOAA/NWS cuts are just as alarming as anything happening at FAA.
27.02.2025 23:20 — 👍 1531 🔁 569 💬 30 📌 17IMO'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:

Lisbon
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!

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.
