Experts raise their concerns as local authorities coordinate preventive evacuations across the Magallanes region.
A tsunami alert was issued today in Chile following a 7.5-magnitude earthquake near Puerto Williams, located in the far south of the country. According to official information from SHOA (Hydrographic and Oceanographic Service of the Chilean Navy), the event could cause significant impact in various areas of the Antarctic and Magallanes territory over the coming hours.

“Tsunami waves ranging from 1 to 3 meters above tide level are possible along some coasts of Chile,” states a report from the USGS (United States Geological Survey). The agency also warns of possible sea level rises of 0.3 to 1 meter along parts of the Antarctic coastline.
