Ubehebe crater. A phreatomagmatic eruption, where magmas impinge upon wet sediment or groundwater causing rapid vaporization. Volume expansion during vaporization causes the water saturated overburden (roof) to explode. Sudden depressurization causes magma to then erupt catastrophically.

โ๏ธ๐งชFiery Mud Volcano Eruption!
The Daลmษrdan (Dashmardan) mud volcano in Azerbaijan erupted ~16:50 on the 30th Jan 2026. The eruption lasted ~15 mins and was accompanied by a pillar of flame several hundred meters high. Daลmษrdan had previous documented eruptions in 1866, 1954, 1976, 1986 and 2011.
SeisBench v0.11 is out now, the largest feature and performance update to SeisBench so far! In this thread, I'll highlight some of the key contributions. Thanks to everyone who helped putting together this release!

Alex Pretti, wearing a green sweater with his VA badge on.
This is Alex Pretti.
This morning he was murdered by ICE. Six ICE agents held him down and shot him at point blank range. Alex was a nurse and researcher at the VA.
Our thoughts are with his loved ones and we stand united in action calling for the abolishment of ICE.

Volcanic features offshore Mayotte and seismic/hydrophone stations used. The network includes four onshore broad-band (BB) stations (black), one accelerometer (red) and multiple ocean-bottom hydrophones (OBH, orange). Offshore stations combine deployments MAYOBS1 (FebโMay 2019) and MAYOBS2 (MayโOct 2019). An asterisk (e.g. MOC*โ ) marks instruments redeployed across campaigns. P-T is Petite-Terre, east of Mayotteโs main island. Geomorphological boundaries and volcanic features (shaded areas in the bathymetry) follow N. Feuillet et al. (2021); V. Puzenat et al. (2022). Bathymetry is from MAYOBS campaigns (S. Jorry 2019).

The portable computer processing Early-Est died. As I have no funding for time or hardware to run Early-Est here, I am waiting to see if an opportunity to easily set-up and run Early-Est on freely available or surplus hardware arises.

Wanna see how an earthquake works? Here's today's lab in my seismology class. An explanation follows.
๐งช
We conclude DL based monitoring can rapidly produce more consistent picks & better catalogs than standard procedures, freeing analysts for improved quality control, analysis, & dissemination of information on seismic activity, especially during significant seismic sequences.
doi.org/10.1093/gji/...
Violin plots of the distribution of the weighted RMS of the earthquake locations for the three pick collections used in the tomographic inversion (BSI-R, PN-IN and PN-OR). Panel (a) shows the weighted RMS for relocation of the 2000 earthquakes used for the inversion whereas (b) shows the weighted RMS for relocation of all the studied events adopting the inverted velocity model. The thick solid line indicates median value and the dashed lines the lower and upper quartile.
The tomographic inversions for 3D, seismic P- and S-wave velocity models show better convergence and more organized earthquake relocations using the DL picks than with the routine picks.

Cross-sections of BSI-R (aโc), PN-OR (dโf) and PN-IN (gโi) NLL-SC relocations. Each cross-section shows seismicity within ยฑ3 km of the section. Events colour is based of event origin time. Main shocks are shown as yellow stars.
Hypocentre separation compared to waveform coherence for the three relocated catalogues. Upper panel: Statistics of 3-D distance between final NLL-SSST hypocentres for event pairs from the 3 catalogues plotted as a function of binned NLL-coherence waveform coherence for each pair. Horizontal bars show median values, vertical bars show 10โ90 per cent quantile range. The BSI-R and PN-IN results are offset horizontally for clarity. Lower panel: relative number of event pairs in each waveform coherence bin; the total number N of event pairs for each catalogue is indicated in the legend.
Relative to location with routine picks (BSI), locations using DL picks (PN) show improved organization and clustering, and, in a ground-truth test, smaller hypocenter separation for event pairs with more similar waveforms.

Map of the central Apennines area indicated by the blue rectangle in the inset. Seismic stations used in the analysis are shown as triangles coloured according to network codes. Purple dots are the 84 991 earthquakes detected and located by BSI in the time period 2016 August 15โ2017 August 31. Yellow stars are the three main shocks of the central Apennines seismic sequence.
Histograms of P (a, c) and S (b, d) pick difference for PhaseNet Original (PN-OR) and PhaseNet INSTANCE (PN-IN) with respect to INGV manual phase picks (BSI). Panels (e) and (f) show the histograms of P and S pick time differences for PN-OR with respect to PN-IN. Medians and Means are represented as red dashed and blue solid lines, respectively; ยฑ1 and ยฑ2 standard deviations are in dashed green and purple lines, respectively.
New paper! We compare PhaseNet (PN) #deep-learning (DL) with manual (BSI) event picking for routine seismic monitoring by analyzing high-precision earthquake locations and tomographic inversion for the 2016 Central Italy #earthquake sequence. doi.org/10.1093/gji/... @carlo-giunchi.bsky.social

Just after midnight on 1 January 2026, a new eruption started from #Etna's eastern flank: a fissure opened at ~2100 m elevation, and a lava flow is descending through the desert-like Valle del Bove. Photos taken in the evening of 1 January from Etna's east and southeast flanks

A jet of incandescent lava fragments shoots from a vent that opened on the morning of 27 December 2025 on the upper eastern flank of the Voragine crater at the summit of Etna, on the evening of the 28th. This type of activity is known as "Strombolian", after the volcano Stromboli in the Aeolian Islands north of Sicily. The snow-covered peak at right is the Southeast Crater, which last erupted in August 2025. View from the town of Nicolosi, on the south flank of Etna.

Eruption column produced by the first paroxysmal eruptive episode at Etna's Northeast Crater, on the morning of 27 December 2025, recorded by a monitoring camera of the INGV-Osservatorio in Bronte, on the western flank of the volcano.
Eruption column produced by the second paroxysmal eruptive episode at Etna's Northeast Crater, in the afternoon of 27 December 2025, recorded by a monitoring camera of the INGV-Osservatorio at the Montagnola, high on the southern flank of the volcano.
Minor explosive activity from a vent on the east side of Etna's Voragine crater at sunset on 27 December 2025, recorded by a monitoring camera of the INGV-Osservatorio at the Montagnola, high on the southern flank of the volcano.
Not one, but TWO paroxysmal eruptive episodes at #Etna 's Northeast Crater on 27 December 2025, AND minor activity at the Voragine crater. Though the Northeast Crater has frequently shown minor activity in recent decades, its last paroxysmal episode was on 27-28 March 1998.
