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…

The great work by our PhD candidate Ai Lun is published: „Photogrammetry and analogue experiments in 3D-printed mold applied to the 2022-2023 lava emplacement at Lascar Volcano in Chile“. Check it out here: nature.com/articles/s4324…

Our new paper on "Volcanic Eruptions and Moss Heath Wildfires on Iceland’s Reykjanes Peninsula" is now out in GeoHazards. Website: mdpi.com/2624-795X/6/4/…

New paper alert. Volcanic crisis reveals coupled magma system at Santorini and Kolumbo. Great work led by Marius and Jens, thanks all for working on that together! It can be found in today’s issue of Nature. nature.com/articles/s4158…

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…

Meet Dr. René Mania — newly minted PhD in remote sensing at University Potsdam! Today he successfully defended his thesis on volcanic deformation and plumbing systems. Huge congrats! 🌋👏 #RemoteSensing #Volcanoes ⁦@GFZ_Potsdam⁩

The cross-section over the ridge shows the clustered seismicity in the middle to upper crust.

Dear fellows; it is time to leave X /twitter. You will find me and follow my work at a place that is less cloudy… Hope to see you there!

Jacob Brauner just successfully defended his PhD. His works on the volcanoes of Bioko island are exciting and let us all hope for more!! Congratulations Jacob!!

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?

Fuck! Not again! On our volcanology tour in northern Chile.

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

Continuation of our drone survey over the Lastarria volcano, Chile. Perfect conditions and a lot of fun watching the amount of data grow!
