A 6.4-magnitude earthquake reverberated through Northern California early Tuesday, leaving more than 70,000 customers in Humboldt County without power on Tuesday, according to Poweroutage.us.

The earthquake was recorded at 2:34 a.m., with an epicenter in the Pacific Ocean, about 7.5 miles from the city of Ferndale, located about 280 miles north of Sacramento. Smaller quakes were reported throughout the morning hours, and damage assessments are still taking place.

Two hospitals in the area lost power and were running on generators, the Sacramento Bee reported Tuesday. Damage to roadways and infrastructure was also reported.

Direct Relief is in communication with the California Governor’s Office of Emergency Services, the California Primary Care Association, the California Department of Public Health, the Health Alliance of Northern California, the North Coast Clinics Network, the Humboldt County Department of Health, Northern California VOAD and other agencies about any medical needs resulting from the quake. Direct Relief also provides ongoing medical support to health facilities in Humboldt and is coordinating around known needs.

After disasters like earthquakes, people are often displaced from their homes and lack access to medications needed to manage chronic conditions. Often, these conditions, if not managed, can force people into local emergency rooms that are already stressed by an influx of patients with acute injuries. Health systems can be particularly stressed in rural areas since there are fewer hospitals and health facilities available.

Direct Relief has responded to multiple emergencies in Northern California in recent years, including multiple large-scale wildfires, and is ready to respond to needs this week as they become known.
