Multiple Earthquakes Shake California, Residents on Alert for More

LOS ANGELES, California — A series of earthquakes have rattled parts of California over the past 24 hours, prompting concern among residents and experts alike. The tremors began early Monday morning, with the seismic activity occurring near the San Andreas Fault, a notorious zone for significant quakes.

The first quake, measuring 3.5 magnitude, struck at 9:44 a.m. PST. Just minutes later, a second quake of 3.0 magnitude followed, also situated along the San Andreas Fault at a depth of 4.6 miles. According to the U.S. Geological Survey (USGS), these early quakes were felt predominantly in areas near San Bernardino, Riverside, and Victorville.

In total, five earthquakes were documented inland in California, with a 2.7-magnitude quake reported at 2 p.m. Monday about 6.2 miles from Ocotillo Wells and a 3.3-magnitude quake occurring shortly before 2:30 p.m. northeast of Little Lake. While the 3.4-magnitude quake reported just before 10 p.m. was felt by over 500 people, the quakes also extended offshore with a notable 4.1-magnitude quake early Tuesday, impacting around 137 residents.

Experts from the USGS emphasized that while minor quakes are common in the region, the recent activity raises alarm due to California’s historical vulnerability to larger seismic disasters. Elizabeth Cochran of the USGS Earthquake Science Center stated, “Overall, Southern California has a 36% chance of a M7.5 or greater earthquake in the next 30 years.” She further cautioned that temporary fluctuations in seismic activity are expected.

The Southern California Seismic Network offered additional insights, noting, “There is a small chance (about 5%) that a larger quake could occur, with the likelihood decreasing over time.” Residents are encouraged to stay prepared for potential aftershocks and larger seismic events.

Emergency preparedness measures have been highlighted in light of these events. The Department of Homeland Security suggests that individuals develop family emergency communication plans, compile a supply kit, and familiarize themselves with safety protocols. “Earthquake safety starts with preparation,” advised a spokesperson.

In response to the earthquakes, community members are using apps such as MyShake to receive immediate alerts. Dr. Jess Johnson, a geophysicist, noted that while the current tremors are “fairly small” and felt by only a handful of residents, they serve as a reminder for Californians to stay vigilant.

As seismologists continue to monitor the situation, residents are advised to remain alert and have a plan in place. The string of earthquakes may signify a more significant event to come, with experts urging continuous preparedness in “earthquake country.”
