At least 20 apartments were damaged by the latest earthquake to rattle the region of Northern California where a stronger quake nearly two weeks ago killed two people and knocked homes off their foundations, authorities confirmed this week.
The magnitude-5.4 aftershock struck at 10:35 a.m. on New Year’s Day about 9 miles southeast of Rio Dell in Humboldt County, according to the U.S. Geological Survey.
Kyle Knopp, Rio Dell’s city manager, said inspectors on Monday red-tagged 20 residences at a single apartment complex. Knopp said inspections were ongoing and officials expected to find additional homes rendered uninhabitable by the latest quake.

A magnitude 6.4 earthquake struck northern California on Tuesday, according to the U.S. Geological Survey.
Very strong shaking was reported from the quake, which struck in Ferndale roughly 200 miles north of San Francisco in the vicinity of the Mendocino triple junction where the Pacific, North America and Juan de Fuca plates meet, according to the USGS.
A Southern California regional passenger rail service announced that it is testing technology that will use the West Coast’s earthquake early warning system to automatically slow or stop trains before shaking begins.
The five-county Metrolink system said the technology is an advancement of a previous version deployed in September 2021 that sends automated messages instructing train crews to slow or stop but does not have automated braking.
