Since the #eruption began, the #earthquakes have moreorless stopped, and been replaced by seismic tremor. This is the incoherent background “hum” caused both by magma moving beneath the ground and venting at the surface - seen mainly at higher frequency (blue & green 2nd plot).

If you look closely at the seismogram from @naspmon station faf, you can see a final burst of small earthquakes as the magma forced its way to the surface. Even better, they are located just beneath the eruption site where we now know the magma is! Which all makes sense. 🌋

Beautiful plot from Egill - this zoomed in view explains the different appearances of intense seismicity (spiky! -- started at arrow #1 ) and eruption tremor (smooth, sustained high amplitudes -- started at arrow #2 ) Plot: c/o @Vedurstofan

🌋The new #Fagradalsfjall eruption started rather quietly at 13:18 ca. according to a tremor plot from our @naspmon @isor_iceland seismic station FAF, which is at ~2 km distance from the eruptive fissure. The spikes are larger magnitude #earthquakes . Plot © @Vedurstofan .

Such a pleasure to have @krjonsdottir open the volcano seismology session this morning!! Wonderful talks on Kīlauea, Sierra Negra, Askja and of course Fagradalsfjall! 🌋🔥 #BSM2022

Today's challenges were different.. 0.5m of snow makes installing seismometers difficult! ❄❄Nevermind driving and hiking.. but overall we installed 3 of the 4 planned, and made it out safely. Thanks to @SEIS_UK for getting the kit together so quickly! @EarthSciCam @CamVolcSeis

Today we were working in #Reykjanes . Lunch at LAMB (overlooking lake Kleifarvatn), a battery swap at Hellur (station code HELL! 🔥), and a more serious power overhaul at VATN, which has been struggling in the fog. Sadly the eruption was still on pause.. @Conor__Bacon @EarthSciCam

And if you like #earthquake movies.. well, this one is feature-length 😅 Feat. @quakemigrate locations for 155,000 earthquakes over 13 years. Location is the area around #Askja #volcano , Central Iceland. (Full video at link above - trimmed for Twitter)

Comparing satellite images of Iceland during winter and summer it becomes evident that the island deserves its name. Image source:

#Askja still going up! 🌋📈 (and I can confirm the weather deterioration first hand - amazing that InSAR can still see through so much snow ❄)

The uplift in #Askja is still ongoing with a roughly constant rate. This is a #Sentinel1 interferogram (Jul 31 – Sep 23) showing ~12 cm of range decrease signal. The coherence in the last days decreased suggesting that the weather got worse.
