Earthquakes

A massive body of magma surged upward beneath São Jorge Island in Portugal's Azores archipelago in March 2022, triggering thousands of earthquakes before stalling underground. The event, detailed in a new study, represented a failed eruption that raised but ultimately eased fears of volcanic activity.

A new study indicates that the Cascadia subduction zone and the northern San Andreas fault may trigger earthquakes in close succession, potentially amplifying disaster risks along the U.S. West Coast. Researchers identified evidence of such synchronization in ocean floor sediment cores spanning 3,100 years. This connection could affect cities from San Francisco to Vancouver simultaneously.

A new analysis of sediment cores from a Nepali lake reveals that major earthquakes in the central Himalayas occur randomly rather than at regular intervals, challenging fears of an imminent massive quake. Researchers identified at least 50 events of magnitude 6.5 or larger over the past 6,000 years, including eight since 1505. This finding suggests the region has experienced more seismic activity than previously thought.

A joint Chinese-Chilean expedition will plumb the uncharted depths of the Atacama Trench in the Pacific Ocean. Setting off from Valparaiso aboard the Chinese research vessel Tan Suo Yi Hao, the three-month mission seeks new life forms and insights into earthquakes and tsunamis. The collaboration provides Chilean scientists with tools no other country possesses.
