⚒️ 🧪 A M6.8 earthquake struck offshore Japan today - another large earthquake from the subduction zone that produced two recent great earthquakes. The earthquake was preceded by a "cascade up": foreshocks progressively increasing in maximum magnitude. What do we know? What might happen next?

⚠️ Faults don’t slip evenly!! Varying slip rates along faults drive complex earthquake cycle patterns, yet they are overlooked in seismic hazard assessments. Read more: seismica.library.mcgill.ca/article/view...

It was a pleasure to contribute to this article, which talks about how AI contributes to seismology - indeed, we have seen tremendous progress in the use of machine learning to detect small events. 1/

SeisBench v.10 is out and it's time for some new models: - SkyNet allows picking regional phases and can even distinguish Pn, Pg, Sn, Sg (beware of the Terminator though) - SeisDAE brings easily retrainable seismic waveform denoising Check out all changes here: github.com/seisbench/se...

⚒️ 🧪 A M7.4 earthquake struck Russia's Kamchatka peninsula today: the largest aftershock so far of the great M8.8 on July 29th. What do we see in the seismic data so far? And what are the chances of a triggered earthquake next door? earthquakeinsights.substack.com/p/m74-earthq...

⚒️ 🧪 If you've seen breathless reporting about a seismic swarm near a "supervolcano" in northern Nevada, don't worry: that is just where Yellowstone was, 15 million years ago. There is no supervolcano there now. But the swarm, and the geology here, is pretty neat! Read about it in our latest post:

🔥OPEN ACCESS+PRESS RELEASE🔥 A new #TSR study suggests that the 28 March 2025 magnitude 7.8 Myanmar earthquake's southern section ruptured at supershear velocity, reaching speeds of 5 to 6 kilometers per second. PR: www.seismosoc.org/news/first-a... Paper: pubs.geoscienceworld.org/ssa/tsr/arti...

⚒️ 🧪 A M7.3 earthquake struck offshore Alaska yesterday. This is the sixth earthquake above M7 in this small stretch of the subduction zone since 2020. This was a weird strike-slip earthquake, reminiscent of a similar quake in 2020. Did these ruptures happen in the slab, the upper plate - or both?

Temblor's latest, by @beccapox.bsky.social, looks at how modeling of slow-slip earthquakes can also help scientists understand slow-moving landslides, a common hazard along the U.S. West Coast. ⚒️ temblor.net/earthquake-i...

⚒️ 🧪 A M6.7 earthquake struck below the Weber Deep yesterday (a part of the Banda Sea, in eastern Indonesia). Actually, lots of earthquakes strike below the Weber Deep. What’s going on down there? We explore how curved subduction zones might cause strange stresses in sinking slabs.

I generated a quick map with past seismicity and it appears that M5ish earthquakes have previously occurred near the North coast of Greenland. Today’s M5.8 event is the pink square. ⚒️🧪

Gardonio et al. reveal a seismicity acceleration that began a year before the 2015 Mw 7.9 Gorkha earthquake in Nepal, with small quakes clustering near the rupture zone initiation. Early warning signs? [@lgltpe.bsky.social] Read more: seismica.library.mcgill.ca/article/view...

I first thought that this event was unusuall deep for an intraplate crustal event. However, it seems that the depth (25 km) is within the seismogenic volume inferred from the background seismicity, yet, still at the bottom of seismogenic depth.

Regional phase picker does seem very innovative!

Aguilar Suarez & Beroza present a deep learning phase picker to capture arrival times from earthquakes at regional distances, intended for sparse seismic networks or remote regions. Read now: seismica.library.mcgill.ca/article/view...

Published!!!! The first article of my PhD and the first from the lab that I set up!! 🤩🤩 We study the dynamic effects of fault bends on earthquake ruptures by imaging shear ruptures in PMMA plates propagating through bends (double bends to be exact). www.pnas.org/doi/10.1073/... ⚒️🧪

Is supershear the norm, say, to be expected along the San Andreas system? For the larger (M>7.2 or so) recent strike-slip events, it seems supershear is being more typically observed lately. This study from 2022 found evidence of supershear for 12 of 87 (14%) of M>6.7 www.nature.com/articles/s41...

Surface rupture of bsky.app/profile/maxv... suggests a remarkably smooth & geometrically simple rupture surface at depth: Black line is a simple spline controlled only by the two blue points. Perhaps important implications for large earthquake rupture physics & why this may be a super-shear rupture.

There is something horribly sobering about this. The deep sea abyssal plains of the Pacific have existed basically unchanged for roughly 80 million years. Over a period of just a couple of weeks in 1979, we changed it during an experimental mining operation. www.nhm.ac.uk/discover/new...

The earthquake that hit Myanmar last week appears to have been a rare type known as supershear - in which the energy of a rupture moves exceptionally fast through the ground, amplifying the destruction https://go.nature.com/3DXVQWz

🌟OPEN ACCESS: MYANMAR PAPERS🌟As a service to researchers working on the 2025 M7.7 Myanmar earthquake, we have curated a list of papers related to the region and its faults, free until until April 16. ⚒️ #BSSA: pubs.geoscienceworld.org/bssa/pages/a... #SRL: pubs.geoscienceworld.org/srl/pages/ap...

⚒️ 🧪 New satellite imaging of the Myanmar earthquake area confirms that the rupture was unusually long: ~500 km. We discuss the data, the rupture, and the implications, in our latest post. earthquakeinsights.substack.com/p/surface-ru...

Given that 2025 Myanmar earthquake likely ruptured at supershear speed for considerable distance, I tried Vallée & Dunham (2012)'s method to identify potential Mach cone. I selected the M 5.1 aftershock whose USGS moment tensor is similar to that of the mainshock.

Felipe Vera of @gfz.bsky.social shows an initial bilateral subshear rupture, yet the southward portion propagated much more at supershear velocities, cumulating to a "well over 400 km" long rupture! www.linkedin.com/posts/freder...

Updated map for M7.7 #Myanmar #earthquake now incl. Thai network aftershocks (in purple) and the extent of the USGS slip model (little slip on most S 75 km though). Aftershocks appear concentrated near epicenter and at S end of rupture (and past?). Central section (original gap) less active. 🧪⚒️

New USGS finite fault solution is intriguing. Bilateral rupture: northward rupture extending to the 2012 M6.8 rupture; southern rupture involving entire Meiktila segment. Areas of high slip (5-6m), with a lower slip (2-3m) area correlating with Mw 6.7 aftershock: earthquake.usgs.gov/earthquakes/...
