Do Coupled Megathrusts Rupture?
In our new preprint, @bar_oryan and I present the first global analysis of the relationship between kinematic geodetic coupling and earthquake slip models across 12 subduction zones and 61 megathrust earthquakes.

The first tsunami waves have reached the shores of Severo-Kurilsk, Norther Kuril Islands . According to eyewitnesses, the water swept away a fish processing plant.
Holy shit! This is incredible footage of surface rupture forming on the Sagaing Fault during the #MyanmarEarthquake in Thazi. It's the first time such a phenomenon has been captured!
A basaltic submarine eruption offshore the island of Mayotte between July 2018 & January 2021 is one of the largest documented underwater eruptions. Geoscientists recently analyzed precise earthquake locations & focal mechanisms associated with this event: geosociety.co/MV
ALT Image Credit: Jacques et al. (2024). (a) Three-dimensional (3D) perspective view of Mayotte Island and its eastern slope (threefold vertical exaggeration). Fani Maoré: new volcanic edifice (NVE) and its basanitic lava flows are shown by black contour and reddish shape, respectively. Red dotted line: caldera fault (inferred by Feuillet et al., 2021); Horseshoe and the Crown are volcanic vents and structures related to the inferred caldera fault. The two light-gray shapes are projections on the sea-floor of the envelopes of the Proximal and Distal earthquake swarms that we relocated between February and November 2019 and that are related to the Fani Maoré eruption.
Top right inset: geographic setting, red star: location of Fani Maoré eruption and black dotted line: nascent transform plate boundary between Somali and Lwandle plates (e.g. Feuillet et al., 2021).
2024 un gran año para la consolidación de la inteligencia artificial para el gran público. Por ejemplo este artículo muestra como ChatGPT puede ayudar a traducir los estudios que hacemos los científicos para que sean comprendidos por los políticos que toman las decisiones. 📝
Excited to share our research on active, long-lived upper-plate splay faulting in the Alaska subduction zone. New thermochronologic data reveal the exhumation history in the forearc region and persistent inboard deformation along the Kodiak Shelf Fault. doi.org/10.1016/j.epsl.2024.…

🌍 Why did the NW Zagros foreland basin accumulate up to 4 km of sediments during the Neogene, deeper than expected, given the nearby moderate topography?
