A series of small earthquakes struck near the Big Bear region in the County of San Bernardino from late Saturday evening until Sunday morning.
Earthquakes – which reached the magnitude of 3.5 before sunrise on Sunday – had an epicenter in the mountains of San Bernardino about four miles north of Big Bear airport.
The epicenter was approximately 29 miles northeast of the city center of San Bernardino, 27 miles south-east of Hesperia and 40 miles northwest of Palm Springs.
The first earthquake was magnitude 3.3, which struck on Saturday at 11:15 p.m., according to US Geological Survey.
It was followed by a magnitude 3.4 to 2 h 51 the magnitude 3.5 Temblor followed at 3 h 41
A replica of magnitude 2.5 was reported at 5:54 am, followed by an earthquake from 2.6 to 6:20
According to the USGS, “low” tremors – or a level three on the intensity scale of modified Mercalli – were felt in the Big Bear area. In general, that is enough to feel significantly by people inside, but many people may not recognize it as an earthquake. Vibrations in these tremors may look like a truck.
The last time that the Big Bear region was affected by major earthquakes, it was in 1992. On June 28, 1992, an earthquake of magnitude 6.3 affected about 4½ miles in the southeast of Big Bear airport, causing serious jerks in the Big Bear region.
No life was lost in the Big Bear earthquake of 1992, said the USGS, but there were substantial damage and landslides in the region, and this earthquake was largely felt in southern California and in certain parts of southern Nevada and western Arizona.
The 1992 Big Bear earthquake was the second with a punch of Temblors that occurred the same day. Three hours earlier and about 20 miles to the east, the powerful earthquake of moor of magnitude 7.3 struck.
The moor earthquake had an epicenter more than 25 miles northeast of Palm Springs, and resulted in serious tremors in the Yucca valley, and strong tremors in the palm trees of Twentynine, according to the modified Mercalli intensity scale.
A sleeping 3 -year -old boy died after being struck by a fireplace collapse in the earthquake tremor.
These earthquakes were preceded by an earthquake of magnitude 6.1 on April 22, 1992 in Joshua Tree National Park. This earthquake began a sequence of triggered earthquakes that migrated north in the following months, culminating in moor and earthquakes of Big Bear in June 1992.
