25 September 2024–The five largest continental transform earthquakes since 2000 all originated on a branch of the main fault—and two researchers predict that the next great earthquake of this type will also get its start on a branch or splay fault. Last year’s magnitude 7.8 Pazarcık earthquake in Türkiye was … Continue Reading »

Sichuan Province Earthquake Offers Lessons for Landslide Prediction from GNSS Observations

Landslides along a river in Sichuan, China following the 2022 Luding earthquake

7 August 2024–Using data collected from a 2022 magnitude 6.8 earthquake in Luding County in China’s Sichuan Province, researchers tested whether Global Navigation Satellite System (GNSS) observations could be used for rapid prediction of earthquake-triggered landslides. In their report in Seismological Research Letters, Kejie Chen of the Southern University of … Continue Reading »
