Nearly 60,000 Homes Without Power After Magnitude 6.4 Earthquake Rocks Humboldt County

A powerful earthquake rocked the Northern California coast early Tuesday, jolting Humboldt County residents awake as it shattered glass, shook homes off foundations, damaged roads and left nearly 60,000 homes and businesses in the rural area without power and many without water.

At least a dozen people were injured.

The magnitude 6.4 earthquake occurred at 2:34 a.m. near Ferndale, a small community about 210 miles northwest of San Francisco and close to the Pacific coast. The epicenter was just offshore at a depth of about 10 miles. Numerous aftershocks followed.

“It felt like my roof was coming down,” said Cassondra Stoner. "When I woke up, the only thing I could think about was, ‘Get the freaking kids.’”

When the ground stopped moving, Stoner's family was fine — a daughter even slept through the racket. But when she showed up to work at Dollar General, she found that tiles had fallen from the ceiling, shelves were toppled and the contents of the discount store were scattered on the floor.

No tsunami was expected, the Humboldt County Sheriff’s Office tweeted shortly after the quake hit.

Residents in the area known for its redwood forests, scenic mountains and the three-county Emerald Triangle's legendary marijuana crop are accustomed to earthquakes. But many said this was more violent and unnerving than the usual rolling motion they experience.

“You could see the floor and walls shaking,” said Araceli Huerta. “It sounded like a freight train was going through my house.”

Damage to buildings and infrastructure was still being assessed Tuesday afternoon. Two Humboldt County hospitals lost power and were running on generators, but the scale of the damage appeared to be minimal compared to the strength of the quake, according to Brian Ferguson, spokesperson for the California Governor’s Office of Emergency Services (Cal OES).

Approximately 12 people were reported as suffering injuries, including a broken hip and a head wound, the Humboldt County Sheriff's Office said at a news conference Tuesday morning, which was interrupted by a jarring aftershock. Also, two people died — an 83-year-old and a 72-year-old — because they couldn't get timely care for "medical emergencies” during or just after the quake.

Damage was mostly focused on the small communities of Rio Dell, Ferndale and Fortuna, Cal OES Director Mark Ghilarducci said during a news conference in Sacramento.

Rio Dell, a hamlet of about 3,000 people, was hardest hit by the quake, where at least 15 homes were severely damaged and deemed uninhabitable and 18 others were moderately damaged, officials said after a partial assessment.

The city’s water system was shut down to repair leaks and will be offline for as long as two days, with portable toilets set up at City Hall and water being handed out at the fire house.

A bridge over the Eel River built in 1911, which is the main route into Ferndale, was damaged and closed to traffic, requiring a longer detour through the mountains to reach the quaint Victorian town, where all of Main Street is on the National Register of Historic Places.

Caroline Titus, former owner of the Ferndale Enterprise newspaper, said the quake only broke a few windows on storefronts. At her 140-year-old home, though, plants were knocked over, her coffee bar crashed to the floor, pictures fell off the wall and books tumbled from shelves.

“It’s all just pain-in-the-butt type of damage,” Titus said.

The earthquake occurred in an area known as the Mendocino Triple Junction, where three tectonic plates meet.

“We’re in this moment of geologic time where the most exciting, dynamic area of California happens to be Humboldt County and the adjacent offshore area,” said Lori Dengler, professor emeritus of geology at Cal Poly Humboldt.

Since a magnitude 7.2 quake jolted the area in 1992, injuring hundreds, sparking fires and destroying many homes, building codes have required retrofits to make structures much more resilient to the shaking, Titus said.

Still, she said, each strong quake evokes the same fear: “Is this the one. Is this the nine-pointer?”

“Then you’re thinking, ‘I’ll just ride it out,’” she said. “Then the adrenaline catches up with you and there are a lot of swear words.”

The power outage involved the main transmission line that runs into the region, and Pacific Gas and Electric’s restoration work was slowed because rain prevented use of a helicopter to assess damage, said state Sen. Mike McGuire, a Democrat who represents the area.

The utility said it expected electricity to be restored within 24 hours, but 57,000 customers remained without power by mid-afternoon Tuesday.

The nearby city of Eureka, with a population 26,000, said on its website that “no significant damage” was immediately reported.

Eureka resident Dan Dixon said he and his wife were sleeping when the quake jolted them awake and shook everything, throwing pictures in their home to the ground.

“It was probably the most violent earthquake we have felt in the 15 years I have lived here,” he said. “It physically moved our bed.”

Larkin O’Leary, 41, of Santa Rosa, traveled to spend her anniversary with her husband in Ferndale, where they had been shaken by an earthquake last year. They decided to try again and booked the romance package at a historic inn, the same spot as a year ago.

O’Leary said she woke at 2:30 a.m. with an eerie feeling and tried to go back to sleep.

“I laid back down again and it was almost as if someone jumped on the bed,” she said. “It was so terrifying. ... It shook in a way I had never experienced. It was up, down, all around."

The couple quickly got out of Ferndale and returned to their home.

“Never again,” O’Leary said.

The quake triggered a massive response by the West Coast's warning system that detects the start of a quake and alerts people by cellphone in the affected region to take safety precautions in the seconds before strong shaking reaches them.

The system pushed out alerts to some 3 million people in Northern California early Tuesday, state officials said.

The earthquake came just days after a small magnitude 3.6 earthquake struck the San Francisco Bay Area, waking up thousands of people before 4 a.m. Saturday and causing minor damage.
