SAN BERNARDINO COUNTY, Calif. – Three earthquakes struck in the Inland Empire overnight, data from the U.S. Geological Survey shows.
What we know:
The USGS said the first two temblors happened in Ontario.
The first hit at 1:02 a.m. Wednesday, Aug. 6. It was a preliminary 3.5-magnitude earthquake at a depth of about 4 miles.
Just 12 minutes later, an earthquake struck in the same area, also a 3.5-magnitude earthquake, data from the USGS revealed. The second had a depth of about 3.7 miles.
At 2 a.m., a third earthquake, the biggest of the series of overnight quakes, struck in the Lytle Creek area. The 3.7-magnitude earthquake had a depth of 6.5 miles.
USGS’s “Did you feel it?” map shows the third quake was felt across the IE, as well as parts of Los Angeles and San Diego counties.
