According to the USGS, a preliminary magnitude 4.6 earthquake occurred at 4:18 p.m. on March 28, 2023, 4.3 miles west-southwest of Ferndale at a depth of 9.6 miles.

This earthquake is one of the largest to hit the region since the 6.4 Dec. 20 quake and 5.4 New Year's Day aftershock and is believed to be an aftershock of the Dec 20 M6.4 Ferndale earthquake.

The Redwood Coast Tsunami Work Group's Facebook page notes that this is the third-largest aftershock recorded to date, and aftershocks can continue for months after a major earthquake, indicating that there may be more seismic activity in the future.

The earthquake has the potential to cause damage to structures, particularly those that were already weakened by the previous earthquakes

Therefore, residents in the area are advised to be prepared for further seismic activity and follow earthquake preparedness guidelines to ensure their safety.
