Overview

• USGS recorded 14 earthquakes of magnitude 2.5 or greater in the past 24 hours across North America and the Caribbean, including seven in the contiguous United States.
• Notable events included a magnitude 3.9 near Valmy, Nevada and a magnitude 5.9 about 231 kilometers west of Bandon, Oregon on September 26.
• The updated national seismic model continues to show the highest hazard in California, Alaska and Hawaii, with increases projected in some areas.
• USGS geophysicist Mark Petersen called the model a major achievement for public safety, noting its usefulness for engineers and policymakers.
• Coverage underscores preparedness and explains that California’s MyShake, Earthquake Warning California and Wireless Emergency Alerts can provide seconds of warning for stronger quakes, with limits near epicenters.
