New paper alert: We studied the InSAR deformation field over Indonesian volcanoes and propose widely applicable processes of material movements and instability. Great work by Edgar Zorn published in Bull Volc! doi.org/10.1007/s00445-025-0…

An eruption style transitional between effusive and explosive activity? Using satellite and drone-based photogrammetry and petrography we describe a strange type of block and ash flow deposits from Bezymianny volcano. Check out doi.org/10.1007/s00445-025-0…

View from the top of Lascar volcano. We used drones to identify new fissures, erosion and rock falls associated with last year's eruption.

Drone image at 5800m showing the crater of Lascar volcano, looking north. See the little people in the foreground? That's us.

A panoramic view from the top of Lascar volcano, ~ 2 years after its last eruption. The air is thin up there!

Members of the @ROTTnROCK team on their trip to study hydrothermal alteration and volcanotectonics in Chile. See the screw in the tyre? That's tyre number 2. We need another spare!

That's Martin and Christian installing a multigas monitoring system at Alitar, a highly variable, hydrothermally alterating and degassing maar-like structure in Chile. @GFZ_Potsdam⁩ ⁦@ROTTnROCK

A view of the packed back of our pickup, with Lastarria's fumarole fields in the background. We have a generator running to charge all the batteries while we continue our survey.

Interesting sulphur structures form in the fumarole field of Lastarria volcano. Some of the tubes are almost 1 metre long and grow downwind. What would you call them?

If you have to cross a strong fumarole field by car - that's Lun, a PhD student in volcanology at the GFZ Potsdam. ⁦@GFZ_Potsdam
