Did you know there was an ice-contact lake in what is now the North Sea? Much farther south than expected. During MIS3. No? Read all about here... www.sciencedirect.com/science/arti...

We reveal, at sub-annual resolution, the ~74 ka Toba super-eruption‘s acute, but short-lived impact on eastern African climate using varved sediments in Lake Chala (Kenya/Tanzania)! www.science.org/doi/10.1126/...
Sub-annual resolution evidence for limited impact of the 74-ka Toba eruption on eastern African climate
Sub-annually resolved lake sediments suggest the Toba eruption caused modest cooling and drought in eastern Africa.

It's #WorldTsunamiAwarenessDay. Before warning systems existed, tsunamis could be a surprise. A 1946 M8.6 earthquake in Alaska launched a tsunami that devastated Hilo, HI and killed >150 in the HI Islands. Now warning infrastructure in AK is being defunded, weakening the network. ⚒️🧪🌊 bit.ly/4oqexnR
Tsunami
56 years ago today a devastating Tsunami tore through our Hilo Town. It may have taken us to our knees, but we did not break. Instead, we rebuilt, stronger, and more prepared. Listen as survivors of both the 1946 and 1960 Tsunami tell their story. Please enjoy this mini Documentary done as a collaboration with Taylor Martin Media and the Pacific Tsunami Museum. Enjoy

Our #land2sea shaking studies workshop in #Taiwan was a success! Many great discussions on the way forward for subaquatic #paleoseismology, inspiring talks and a fantastic field trip showing the impacts of the devastating 1999 Chi-Chi #earthquake. @ecord.bsky.social @paleopizer.bsky.social
🌟OPEN ACCESS🌟 In a new #SRL paper, scientists link coseismic deposits in lakes in Chile with instrumentally recorded megathrust quakes. In this way, they bridge the gap between sedimentology and seismology. ⚒️ pubs.geoscienceworld.org/ssa/srl/arti...
Subaquatic #paleoseismology is a great tool to reconstruct past #earthquakes! But which components of #shaking are the #turbidites we study actually recording? 🤔 💡📢 Find out in my latest #publication ⏬ @seismosocam.bsky.social Another step closer to #quantitative paleoseismology! 👩🔬🥳
