A sequence of small earthquakes hit close to the Large Bear space in San Bernardino County beginning late Saturday evening into Sunday morning.
The earthquakes — which maxed out at magnitude 3.5 earlier than dawn Sunday — had an epicenter within the San Bernardino Mountains about 4 miles north of Large Bear Airport.
The epicenter was about 29 miles northeast of downtown San Bernardino, 27 miles southeast of Hesperia and 40 miles northwest of Palm Springs.
The primary earthquake was magnitude 3.3, which struck at 11:15 p.m. Saturday, in response to the U.S. Geological Survey.
It was adopted by a magnitude 3.4 at 2:51 a.m. The magnitude 3.5 temblor adopted at 3:41 a.m.
An aftershock of magnitude 2.5 was reported at 5:54 a.m., adopted by a magnitude 2.6 quake at 6:20 a.m.
“Weak” shaking — or a Stage Three on the Modified Mercalli Depth Scale — was felt within the Large Bear space, in response to the USGS. Normally, that’s sufficient to be felt fairly noticeably by individuals indoors, however many individuals might not acknowledge it as an earthquake. The vibrations in such shaking might really feel like a truck has handed by.
The final time the Large Bear space was hit by main earthquakes was in 1992. On June 28, 1992, a magnitude 6.3 earthquake hit about 4½ miles southeast of Large Bear Airport, inflicting extreme shaking within the Large Bear space.
No lives have been misplaced within the Large Bear earthquake of 1992, the USGS stated, however there was substantial injury and landslides within the space, and that quake was broadly felt round Southern California and in components of southern Nevada and western Arizona.
The Large Bear earthquake of 1992 was the second of a one-two punch of temblors that occurred on the identical day. Three hours earlier, and about 20 miles to the east, the highly effective magnitude 7.3 Landers earthquake struck.
The Landers earthquake had an epicenter greater than 25 miles northeast of Palm Springs, and resulted in extreme shaking in Yucca Valley, and robust shaking in Twentynine Palms, in response to the Modified Mercalli Depth Scale.
A sleeping 3-year-old boy died after being struck by a collapsing chimney within the Landers earthquake.
These earthquakes have been preceded by a magnitude 6.1 earthquake on April 22, 1992, in Joshua Tree Nationwide Park. That quake started a sequence of triggered quakes that migrated north within the following months, culminating within the Landers and Large Bear earthquakes of June 1992.
