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

Could light-speed gravity signals be useful for earthquake early warning ? Gabriela Arias explored its potential in Chile (collaboration with A. Licciardi, K. Juhel, Pablo Ampuero and B. Rouet-Leduc) agupubs.onlinelibrary.wiley.com/doi/full/10.10…

Je serai en direct sur RFI lundi à 15h pour parler de séismes

👉Sera-t-il possible d’anticiper les #séismes ? Comment détecter des signaux invisibles ? Comme le glissement des failles quelques heures avant les grands tremblements de terre ? Où en est la recherche en sismologie ? Avec Quentin Bletery IRD.fr sur RFI @RFImag à 15h10 heure de Paris

Nota de prensa del Instituto Geofísico del Perú sobre nuestro trabajo conjunto en Inteligencia Artificial para el sistema de alerta temprana del Perú (SASPe) con Pablo Lara Quentin Bletery Adolfo Inza Hernando Tavera Para leer el artículo científico completo: doi.org/10.1029/2023JB… #OpenAccess

Preprint alert: Do large earthquakes start with precursory slow slip? eartharxiv.org/repository/vie…. We review the elements of discussion that have raised following our Science publication last year and address them through a series of tests. Any feedback welcome.

Great AGU session proposed by Hojjat Kaveh on earthquake forecasting physical models

Estimating the magnitude and focal mechanism of an earthquake using only data preceding seismic (P) waves. This is what Kévin Juhel managed to do using the Alaska US array and some deep learning skills. Just out in Nature Com. E&E: nature.com/articles/s4324…

Big congrats to Pablo Lara for winning the Trophées de l'innovation IRD.fr !

We'll be debating with Dr. Judith Hubbard and Kyle Bradley about our respective views of potential precursory signal in GPS data. The event will be hosted by temblor on Tuesday Feb 18 at 17:00 (French time). Join us following the instructions described in this post.

Video recording of the live debate with Dr. Judith Hubbard, K. Bradley and J.-M. Nocquet. Thanks to temblor for hosting this. Any feedback welcome.

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: arxiv.org/abs/2505.15461
