Another cluster of earthquakes was recorded Monday in an area near the Nevada-California line that has been shaken frequently in the past seven months.

Originally estimated at 4.9, the largest quake’s strength was revised to 4.7, the US Geological Survey said. It occurred at 1:20 pm, with an epicenter in the ghost town of Candelaria, Nevada – 15 miles south of Mina and 50 miles east of California’s Mono Lake.

It was followed in the next three hours by a series of aftershocks, six of them ranging from 2.5 to 4.3.

Responses to the USGS Did You Feel It? website indicated it was felt strongly in a 60-mile radius, including the cities of Hawthorne and Tonopah in Nevada and Bishop in California.

The epicenter is within 15 miles of seven quakes this year that were magnitude 5 and above (indicated by orange dots on the map above):
