I have been reelected as President of the Tectonics and Structural Geology Division and Member of the Council (ex officio) of the @egu.eu for another mandate. I want to thank the trust the community put in me. I would do my absolute best to serve the community, and, for that, I count on all of you.

The overlooked genius of geophysics In 1936, seismologist Inge Lehmann was the first in the world to prove that the Earth has a solid inner core. She earned widespread international acclaim — but in Denmark, she received neither the tit...

New look at 1755 quake, Europe’s largest ever, may foretell Atlantic ‘ring of fire’ Analysis suggests Earth’s mantle is peeling from the crust in the eastern Atlantic, a possible sign of the ocean’s eventual closure

Seismic evidence for oceanic plate delamination offshore Southwest Iberia - Nature Geoscience The lithospheric mantle may be delaminating from the crust in an oceanic plate segment offshore Southwest Iberia, which could be the ultimate cause of the 1755 Great Lisbon Earthquake, according to seismic imaging and numerical simulations.

New in @nature.com: research led by @idlearth.bsky.social's @joaocduarte.bsky.social shows the ocean floor off Portugal is peeling away into the mantle.

This rare process may explain the 1755 Lisbon M8.7 quake and could mark the initiation of a new subduction zone.
