Maybe the 2026 event fill the gap between the 1812 and 1900 events..

Ah-ha! The focal mechanism of the M7.2 just got updated: earthquake.usgs.gov/earthquakes/... Now it matches the M7.5.

The automated back projection tool captures both the foreshock and mainshock in one solution and the mainshock alone in a separate one. And they don't remotely agree with each other. 🙂 Foreshock + Mainshock:

Very damaging earthquakes in Venezuela. @judithgeology.bsky.social provides a preliminary summary of what may have been a M7.2 and M7.5 doublet - or a complex rupture. Scientifically, this will be hard to untangle because later P/S arrivals will overlap the wavefield from the first event.

⚒️ 🧪 A catastrophic earthquake just struck northern Venezuela. Large buildings have collapsed, and the USGS PAGER is forecasting thousands of fatalities. Our colleague in Caracas, Dr. Frank Audemard, has shared with us what the earthquake felt like and footage from the region. Here’s what we know.

Who would have thought that HPC people are so great at dancing? The #DurhamHPCDays Ceilidh is in full swing!

Thanks @inseismoland.bsky.social for dropping by. An excellent conference depends on excellent talks!

New paper in press at GJI led by postdoc Yohai Magen (with Dave May and I): “Reduced-order modelling of Cascadia’s slow slip cycles” (doi.org/10.1093/gji/...). Reduced-order models (ROMs) are fast surrogates of costly simulations. They compress the evolving, high-dimensional state of a ...

Reduced-order modelling of Cascadia’s slow slip cycles

Summary. Slowslip events (SSEs) modulate the earthquake cycle in subduction zones, yet understanding their physics remains challenging due to sparse observ

Instantaneous time mirrors (ITMs), creating a "time interface" by abruptly changing material properties, have fascinated physicists for decades. Experiments demonstrating time mirrors for optical and electromagnetic waves exist. But can we also “reflect” a 3D seismic wavefield in time?

A new preprint, led by Bar Oryan, introduces the Coupling Cloud: a community database that curates, standardizes, documents, and disseminates published kinematic coupling models inverted from geodetic data. As of today it brings together 96 coupling datasets drawn from 55 publications spanning

Here is the latest tsunami information for the M7.6 earthquake that just struck offshore northern Japan. The warnings are for waves up to 3 m, but the highest waves measured so far are <0.5 m. It is still possible for larger waves to arrive. 1/2 www.jma.go.jp/bosai/map.ht... ⚒️ 🧪
