A strong #earthquake struck the #Kamchatka Peninsula the night of July 29–30, triggering a #tsunami warning in Pacific. Events like this highlight the seismic threat posed by offshore #subductionzones and their potential for global-scale impact (in terms of human lives and economic consequences)
In the Northern Hemisphere people talk about #climatechange only from June to September.

#Etna is speaking loudly today Its activity intensified, producing an impressive plume, accompanied by pyroclastic flows and, later, sustained lava fountains. This episode comes just as two recent scientific studies offer fresh perspectives on Etna’s internal structure and dynamics.

"You cannot hope to build a better world without improving the individuals. To that end, each of us must work for his own improvement and, at the same time, share a general responsibility for all humanity..." ― Marie Curie Image in the public domain, circa 1900, by unknown author 🧪 ⚛️ #histsci
A few scenes of the new Strombolian activity at #Etna 's Southeast Crater during the night of 15-16 March 2025, seen from 5 km distance. Looks big, but actually this is a rather modest activity for Etna standards.
I’m a big fan of @specfem.org I used it in our 2024 GJI study to generate a waveform dataset for testing a tomographic method and assessing distortions in slab recovery. The geodynamic model and seismic dataset will be publicly available soon for benchmarking! #Seismology doi.org/10.1093/gji/...
