For our seismology friends: The 12 August 2021 South Sandwich Islands earthquake started and ended with some regular ruptures (E1, E2, E4, E5), but in the middle it had a huge subevent E3 that was only visible at very long period. Paper is here: doi.org/10.1029/2021GL…

Great atmosphere last week in the Bedretto tunnel where the FEAR project team plans to induce controlled microseismicity to study earthquake processes. Pic: the improvised FEAR band led by Men-Andrin Meier testing broadband acoustic induction!

Field experiments in an underground lab probe the hydro-mechanics of a natural fault stimulated by fluid injection: the transient evolution of permeability and friction control slip stability. New Nature Communications paper by F. Cappa & L. De Barros Earthquakes Geoazur nature.com/articles/s4146…

Why are supershear earthquakes so rare? We address this question through theory and simulations of earthquake cycles on very long faults. Our new preprint with Pablo Ampuero: essoar.org/doi/abs/10.100…

Cats have extraordinary obstacle avoidance abilities There is also an obstacle memory for the back legs, It will remember the height of the front foot after lifting the front foot, and then raise the back foot to the same height 1/🧵

Postdoc opportunity in seismology + machine learning, to develop a Deep Learning algorithm to denoise data from low-cost seismometers and extract information on earthquake processes, with focus on Raspberry Shake sensors in Haiti: emploi.cnrs.fr/Offres/CDD/UMR…

What is the fundamental relationship between silent earthquakes (slow slip event) and regular ones? A new theory accounting for finite rupture depth gives an insightful answer and can reconcile the current debates. Our Nature Communications paper with Pablo Ampuero nature.com/articles/s4146…

I am very honored to receive a CNRS 🌍 Silver Medal. Huge thanks to my collaborators, especially current and former students and postdocs who turned ideas into reality. It’s been a long, winding and well-shaken road through earthquake research … and there’s still so much to do!

We stacked all the GPS time series ever recorded before large earthquakes. The result is pretty interesting: science.org/doi/10.1126/sc…

This is the first "regular" paper accepted in Seismica's Special Issue on the 2023 Türkiye/Syria earthquakes. Just a reminder that you can submit your contributions to this SI until February 2024! See: seismica.library.mcgill.ca/issue/view/28

We recently started a writing group in the Earthquakes Geoazur team. We meet weekly for 2 hours to write together and share tips on scientific writing. In this recorded seminar, I explain my process to write a (collaborative) scientific paper: youtu.be/jtN-Z-wOAC0?si…

A follow-up analysis by Bletery & Nocquet addresses non-peer-reviewed comments on their Science paper "The precursory phase of large earthquakes" (doi.org/10.1126/scienc…). Reproducible code is provided. The work is undergoing formal peer review. Informal comments are welcome.

Three generations of the Ampuero family at the NMEM 2024 workshop on Numerical Modeling of Earthquake Motions at Smolenice Castle, Slovakia nuquake.eu/NMEM2024/ It was great to see them all advancing earthquake science!

How can we assess a fault system's seismic hazard? Our new Nature Communications paper with Faqi Diao, Pablo Ampuero, and others shows how combining high-resolution fault coupling with a physics-based model reveals max earthquake potential: nature.com/articles/s4146…
