On 28 March 2025, a magnitude 7.7 earthquake struck near Mandalay, Myanmar, killing over 5,400 people. Satellite data revealed a 500-km rupture along the Sagaing Fault, with maximum surface slip of 4.6 meters. The earthquake showed no shallow slip deficit and part of it traveled at supershear speed. Large-magnitude earthquakes (Mw＞7) on the segments that ruptured in this event may recur every 104–131 years, while the northern segment may have a shorter one.

Why do some coral reefs weather marine heatwaves better than others? A new study published in Scientific Reports shows that the answer may lie not only in local ocean conditions, but also in climate patterns that span entire ocean basins. By combining long-term ocean observations with chemical records preserved in coral skeletons, the researchers reveal how large-scale climate oscillations regulate the natural cooling that can help protect coral reefs during marine heatwaves. First author Dr. Hana Camelia and Dr. Thomas Felis from MARUM – Center for Marine Environmental Sciences at the University of Bremen lead the study.

Geologists studying some of the planet’s oldest volcanic rocks have uncovered new evidence that water was playing a major role in shaping Earth’s interior and driving volcanic activity more than three billion years ago.
