Did you miss the 2024 Cargese workshop on earthquakes? No problem, the video recordings are now available at https://t.co/yvpym214Eq and the program and slides at https://t.co/XDYWYinKJk Big thanks to all our speakers for making their materials available to all!
Ready to brainstorm about earthquake processes in a beautiful island? Come to the workshop on "Earthquakes: nucleation, triggering, rupture and aseismic processes" in Cargèse, Corsica, France, October 14-18 2024. Pre-registration is open until June 10: https://t.co/XDYWYinKJk

🔍 On 28/01/2020, the largest recorded earthquake in the northern Caribbean (Mw7.7), ruptured the Oriente fault at a speed faster than seismic waves. A rare supershear event, explained by the fault's characteristics. Read more: https://t.co/XCUaKYF7c0

Seen this Myanmar earthquake video ? We used it to measure, for the first time, the slip velocity along the fault during a natural earthquake. Results demonstrate earthquake ruptures are pulse like and bring unprecedented constraints on earthquake models: https://t.co/qgh5n8x1jQ

Huge (and belated) congratulations to @martijnende for receiving the Keiiti Aki Early Career Award of @theAGU @AGUSeismology for his groundbreaking research in Seismology and beyond, from experimental rock friction & earthquake cycle modeling to Deep Learning analysis of DAS data
📣 🎉 Congratulations to all the Seismology-aligned scientists receiving AGU Honors this year! You'll see that seismology reaches its tentacles into many other aligned fields 🔍 Check out the AGU page for a full list of honorees! https://t.co/OT0yv6mhgt

Here is a youtube livestream of seismic (DAS) data recorded along the submarine fiber optic cables in Chile🤩
📢 Want to know what's happening in central Chile? The @EQ_Geoazur ABYSS team got you covered! We have over 400 km of DAS cables deployed offshore that can detect even the tiniest of earthquakes. And it's all happening live (*): https://t.co/sMvXHDbCdp

Excited to see our work on the 2024 Noto EQ led by @liuwei_xu, Ji Chen, and @LingsenMeng featured on the cover of @ScienceMagazine! Combining seismic & geodetic data, we found complex ruptures in the initial stage of this New Year's EQ that led to violent shaking

How can we assess a fault system's seismic hazard? Our new @NatureComms paper with Faqi Diao, @DocTerremoto, and others shows how combining high-resolution fault coupling with a physics-based model reveals max earthquake potential:

A follow-up analysis by Bletery & Nocquet addresses non-peer-reviewed comments on their Science paper "The precursory phase of large earthquakes" ( https://t.co/rHlLO6UOPJ). Reproducible code is provided. The work is undergoing formal peer review. Informal comments are welcome.

High-time-rate GPS time series have a precursor signal for large earthquake rupture starting approximately 2 hours beforehand.
