🚨New paper!

Our latest study, led by Sophie Vineberg, integrates proximal & distal tephra records to reveal the timing and dispersal of large explosive eruptions at Aso volcano (Japan) 🌋

Dept of Geography's Prof Christine Lane @chslane.bsky.social was at the Romanian Academy, Cluj, for the "Integrating ice core, marine & terrestrial environments" network meeting. The two-day event was a great success, with current and former @camtephra.bsky.social members presenting their research.

Last week PhD student @yqnatdeng.bsky.social and @chslane.bsky.social were sampling cores from an Ethiopian lake…in Aberystwyth! Here’s hoping there’s lots of ancient cryptotephra to be found!

We’ve had two days of science in beautiful Cluj as the “Integrating ice core, marine & terrestrial environments” network met for an open meeting. Photos of past/present @camtephra.bsky.social members presenting their work and the birthday flowers they embarrassed me with. @jinheum.bsky.social

Volcanic ash originating from Russia’s Kamchatka Peninsula canceled Alaska Airlines flights to Nome and Kotzebue Tuesday morning.

The ash plume came from the Klyuchevskoy volcano, prompting an advisory from the Alaska Volcanic Ash Advisory Center.

🌋 Lewotobi Laki-laki volcano is at it again. Biggest hazards are lahars and volcanic ash (the latter being particularly bad for air traffic). Stay safe, Indonesians!

Megadrought Reveals Volcanic Ash at Lake Mead

Volcanic ash from volcanoes in Wyoming, Idaho, and California was deposited in the rocks along the shore. The ash samples ranged from 6 million to 12 million years old.

Welcome home, my beloveds, to #FossilFriday 🧪⚒️.

I've spent most of the week deep in the collection, trying to get a basic count together as we look at moving to a new home. Sometimes you find things you never realized were there all along. Here, plant fossils from the Florissant Fm.

Our good old friend the Laacher See Tephra in a speleothem! #tephratastic @swinnyy.bsky.social
Excited to share our latest research published in @science.org #ScienceAdvances! 🎉
We've discovered the Laacher See eruption 🌋 in a speleothem from Germany, which allows to synchronize European and Greenland Late Glacial climate change.
