USGS Logs 31 Recent Quakes in North America as 4.9 Strikes Adriatic Off Italy

Real-time monitoring shows routine seismic activity with no reported damage, highlighting the value of USGS mapping and preparedness.

Overview

Over the past 24 hours, USGS recorded 31 earthquakes of magnitude 2.5 or greater across North America and the Caribbean, including eight in the continental United States.
The strongest event in the contiguous United States was a magnitude 3.7 about 75 kilometers from Tonopah, Nevada, early Tuesday.
Separately, a magnitude 4.9 quake was detected in the Adriatic near Fano, Italy, with no damage reported so far.
USGS “Latest Earthquakes” maps list recent tremors in Alaska, California, Hawaii, and Puerto Rico, reflecting typical regional seismicity.
Alaska and California register frequent earthquakes due to active plate boundaries, and current reporting commonly uses moment magnitude to describe event size.
