A series of earthquakes shook the California-Nevada border near the Yosemite National Park early Saturday a week after a magnitude 4.1 quake hit the same area.
A magnitude 5.2 earthquake, downgraded from 5.3, struck about 30 miles northeast of Mammoth Lakes with a depth of about 6.2 miles at 7:36 a.m., the U.S. Geological Survey reported.
Another temblor, downgraded from magnitude 4.7 to 4.6, rattled the same area at 9:22 a.m. with a depth of about 4.3 miles.
Two more followed at around 10 a.m.: a magnitude 3.9 before a magnitude 4.1 earthquake centered about 15 miles northeast of Mammoth Lakes.
Renowned seismologist Dr. Lucy Jones said the area east of Mono Lakes “has at times had very energetic sequences with multiple larger events, so we won’t be surprised at more events today.”
Events in the magnitude 7 range hit the region in 1915 and 1954, according to Jones.
“Luckily most of the faults are far from towns,” she added.
A magnitude 4.1 quake, initially recorded at 4.4, hit last Sunday about 40 miles directly south of Saturday’s quakes.
