Butte County Sheriff Kory Honea said the mandatory evacuation order for the area has been reduced to an evacuation warning. Evacuations remain in effect this afternoon, Honea said, calling it a "dynamic situation".
The American Red Cross has launched a massive disaster response in northern California, where almost 200,000 people have been ordered to evacuate due to the potentially catastrophic collapse of the Oroville Dam.
"Some geologists said the enormous weight of the man-made 15,500-acre lake behind Oroville Dam, with its 3.5 million acre-feet of water, might have shifted rock deep beneath the earth, acting as a trigger for the quake and aftershocks", The Times reported. The agency did not disclose the other three people's names.
"I have the clothes on my back".
An evacuation center has been established for Oroville residents at the Silver Dollar Fairgrounds in Chico. "It definitely is a people-catcher", said Brannan Ramirez, who has lived in Oroville for about five years.
"I decided I'd rather be in the house and we can climb on the roof rather than be in the auto if something happens", Miner said.
Dozens of schools in evacuation areas throughout Yuba, Sutter and Butte counties are closed.
Crews have been working day and night to reinforce the emergency spillway of the Oroville Dam.
On softer food prices, CPI contracts to 3.17 per cent in January
Food inflation in January stood at 0.53 per cent, down from 1.37 in December 2016 and 6.85 per cent in January previous year . The annual food inflation was 1.07 per cent in rural areas and (-) 0.31 per cent in urban.
Will that be enough to overwhelm the dam's spillways? "It's very hard", California Gov. Emergency spillways are usually reserved for last-resort situations.
Those warnings described the very scenario that was threatening to unfold, though they were dismissed state and federal regulators who expressed confidence that the dam and its spillways could withstand serious storms.
State authorities and engineers on Thursday began releasing water from the dam after noticing that large chunks of concrete were missing from a spillway.
"We've never seen anything like this in modern times", a state water official told NBC News. That's the worst-case scenario, though.
Lake Oroville is California's second-largest reservoir and the dam is the tallest such structure in the US.
Navy Capt. Jeff Davis said DoD officials are watching closely as the dam erodes. Although the level of the dam's lake is falling fast, more rain is forecast.
But Oroville is bracing for rain on Wednesday that could add a strain to the spillway, and an additional problem looms. Engineers said that despite a huge gash that opened in the concrete channel a week ago, it was their best option for lowering the dangerously high lake level.
Lake Oroville, the emergency spillway, and the damaged main spillway are seen from the air on February 13, 2017, in Oroville, California. Then PG&E removed power lines from transmission towers below the dam's auxiliary spillway to ensure safety should the towers themselves destabilize due to water flow. Managers slowed the release of the water, and on Saturday, Oroville overflowed.
