Magnitude-4.6 Malibu Earthquake Shakes Southern California

Understanding the Impact of the Magnitude-4.6 Malibu Earthquake

The recent magnitude-4.6 earthquake that shook Malibu and its surrounding areas has brought attention to the seismic activity in Southern California.

The Earthquake's Epicenter and Timing

The earthquake struck approximately 7 miles northwest of Malibu, nestled within the Santa Monica Mountains. The timing of the quake, just before 2 p.m., caught many residents and workers off guard, triggering widespread concern and curiosity.

Seismic Activity and Aftershocks

Following the initial tremor, a series of aftershocks rattled the affected area, with magnitudes ranging from 3.0 to 2.7. The frequency and intensity of these aftershocks contributed to the heightened anxiety among residents, raising questions about the possibility of a larger seismic event.

Extent of Shaking and Affected Regions

The impact of the earthquake reverberated across a vast area, spanning from the coast to inland regions of Southern California. Reports of shaking poured in from downtown Los Angeles, the San Fernando Valley, South Bay, Riverside, Orange counties, and beyond.

Eyewitness Accounts: Personal Experiences of the Earthquake
