Paleoseismic activity in the moon’s Taurus-Littrow valley inferred from boulder falls and landslides
The lunar landscape has been changed by strong seismic shaking from moonquakes potentially hazardous to long-term infrastructure.

New paper by @diegosismologo.bsky.social and others out now about the 2025 M7.8 Myanmar earthquake. Includes some of the paleoseismic results from trenching we did a fews ago before the earthquake.

🌏A Supershear Earthquake Strikes Myanmar: Fast, Long, and Repeating
Melgar et al. reveal a fast 450 km rupture from March 28 M7.8 quake, ties to past Sagaing Fault quakes, highlighting seismic repeatability & the urgent need for resilience.

Survivors of the 1 September 2025 earthquake in Afghanistan have correctly assessed that rainfall-triggered landslides are much more likely in the aftermath of the mainshock. This illustrates how landslides extend the impact of an earthquake in time and space.

Afghan earthquake survivors refuse to return to villages, fearing landslides
Haunted by the fear that aftershocks could bring rocks crashing down from the mountains, the survivors of Afghan earthquakes vowed not to return to destroyed villages but camp in fields and on riverbanks instead, even without tents to keep off the rain.

Tom Rockwell (Distinguished Lecture) kicking off the 2025 SCEC meeting! Small offset per event (smaller magnitude) produces narrower damage zone in nearby rocks. Serves as a proxy for max magnitude per rupture event. #scecmeet #scec2025 🧪
Tom Rockwell standing on the stage in front of 4 chairs. On the left is a large projection screen showing one of his slides that includes a photomicrograph of fractured mineral grains. A slide from Tom’s talk showing an annotated aerial view of the San Andreas Fault near Little Rock and a photomicrograph on the right showing pulverized mineral grains from a sample collected several meters from the main fault plane. Summary slide of Tom’s talk labeled: General Summary of Physical Damage. Includes three categories: small displacement (less than 1 meter), moderate (1.5 to 2.7 meter), and large displacement (3 to 6 meters).

Published in #GJI Geophysical Journal International: "Geometric control of the 1985 Wuqia Earthquake Rupture: insights from optical image correlation", Zhang et al. This is Fig. 1: for the caption & to read the paper please visit academic.oup.com/gji/article/... @royalastrosoc.bsky.social
Tectonic and seismicity of the study area. (a) Topography of the Pamir region and its surrounding areas, along with GPS velocities relative to the stable Eurasian plate (Wang and Shen, 2020). Black and yellow rectangles represent the profile of GPS velocities and location of panel c, respectively. MPT = Main Pamir Thrust, PFT = Pamir Frontal Thrust, STST = Southern Tian Shan Thrust. (b) GPS velocity of profile A-A′ within the black rectangles in (a). (c) is a zoom of the yellow rectangular region in panel (a). Blue and purple polygons indicate the coverage areas of the KH-9 panoramic and WorldView-3 images, respectively. Red, pink focal mechanisms depict the main shock and aftershocks of 1985 Wuqia earthquake, as reported by Burtman & Molnar (1993), Fan et al. (1994) and GCMT (https://www.globalcmt.org/). Cyan dots represent magnitude < 5.0 earthquakes. Epicentres of historical magnitude ≥ 5.0 earthquakes in the period 1969–2020 from USGS (http://earthquake.usgs.gov/earthquakes/) and Li et al. (2019) are shown as black focal mechanisms and yellow dots. TT = Tuomuluoan Thrust, WHSL = Wuheshalu syncline, KES = Kongur Extensional System. (d) Red solid line and green dots represents the coseismic surface ruptures from field investigation (Feng et al. 1987, 1988) and red dashed line shows an inferred rupture of 1985 Wuqia earthquake from Li et al. (2019). Purple crosses correspond to the location of the GCPs for image registration in Section 3.1.

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! 👩‍🔬🥳

Why the Russian Earthquake Didn’t Cause a Huge Tsunami
Russia’s magnitude 8.8 earthquake spawned serious tsunami warnings, but waves have been moderate so far. Here’s the geological reason why
