One person in Rio Dell, California, died, the city's mayor Debra Garnes told The Los Angeles Times.

Authorities had received an alert about someone who was having trouble breathing during the earthquake. They ultimately went into cardiac arrest and medical staff gave them CPR. They were rushed to the hospital, however, they later died, Garnes said per the outlet.

It hasn't been confirmed if that individual was included in the two people mentioned by the HSO.

Describing the natural disaster, Garnes told The Times "It was the most intense earthquake that I've felt. It was a long-duration earthquake, so it was not only significant in size at 6.4, it was also long."

The HSO previously said that two people were injured, however, they were expected to recover.

The quake struck the Eureka area just after 2:30 a.m. local time, according to the U.S. Geological Survey. It marked the strongest earthquake California had seen in years, USA Today reported.

Sgt. Caleb Carsey with the California Highway Patrol in Humboldt County described the earthquake as "pretty violent," noting there's been extensive damage to roads and homes in Rio Dell, Fortuna, Ferndale and Scotia in the Eel River Valley, according to The Los Angeles Times.

One local resident told The New York Times that although he had been through other earthquakes, he'd "never felt one that hard."

The "earth was just slamming up and down," Joe Filyau, 59, told the newspaper. "Everything in the house is just everywhere."

Following the quake, there have been up to 80 smaller aftershocks, California Governor's Office of Emergency Services Director Mark Ghilarducci said, per CNN.

Officials in Humboldt County are also advising residents to "check gas and water lines for damages or leaks" and to "exercise caution if traveling."
