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.

Scientists have used swarms of minuscule earthquakes to map a hidden and intricate tectonic structure beneath northern California. This region, at the intersection of the San Andreas fault and the Cascadia subduction zone, involves five moving pieces rather than the expected three. The findings help explain past seismic events and improve hazard predictions.
The National Seismological Center recorded several low-intensity earthquakes in various regions of Chile on this Sunday, December 7. Most of these movements were imperceptible due to the country's location at the boundary of the Nazca and South American plates. Senapred provides safety recommendations for such events.

A magnitude 4.0 earthquake struck Álava province and its capital Vitoria just past midnight on December 8, 2025. The epicenter was near Iruña de Oca, about five kilometers away, and was felt in several nearby areas with no reported damage so far.
A team of scientists has uncovered a mechanism that can amplify the magnitude of specific earthquakes by altering fault dynamics. Published in Nature Geoscience, the findings reveal how fluid interactions in fault zones contribute to larger seismic events. This discovery could improve models for predicting earthquake severity in fluid-rich areas.
