Overview

• The USGS recorded 23 earthquakes above magnitude 2.5 in North America and the Caribbean over the past day, including four in the continental U.S.
• The strongest recent tremor was a magnitude 4.6 event 23 km west-southwest of Petersville, Alaska, with additional quakes noted in Hawaii, California, Texas and Puerto Rico.
• Persistent activity in California and Alaska reflects ongoing shifts along the San Andreas Fault and the Pacific–North American plate boundary.
• Mexico’s SSN logged only routine seismic movements, aligning with its annual average of about 90 quakes above magnitude 4.
• Without predictive tools, authorities continue to emphasize evacuation planning, emergency kits and adherence to safety protocols.
