A 7.0-magnitude earthquake occurred off the coast of California, USA, and tsunami warning was issued for the northern coast

A 7.0-magnitude earthquake occurred off the coast of northern California, USA, on the morning of the 5th. There are currently no reports of casualties or property damage.According to detailed reports, the earthquake occurred at 10:44 am local time on the 5th (2:44 am Beijing time on the 6th).The precise location of the epicenter was in the sea 63 kilometers west-northwest of Petrolia, and the focal depth was shallow, only 0.6 kilometers.

The U.S. Geological Survey initially measured the magnitude of the earthquake at 6.6, but later adjusted it to 7.0. It is worth noting that after this earthquake, many aftershocks occurred in the area near the epicenter. This is the strongest earthquake experienced by the region in the past 20 years, since a magnitude 7.2 earthquake occurred locally on June 15, 2005.

In response to the earthquake, the National Tsunami Warning Center under the National Weather Service quickly issued a tsunami warning for the northern coast of California to ensure public safety.

In addition, the earthquake also caused power outages for about 10,000 users in Humboldt County, accounting for about one-tenth of the total local users. Although the damage was relatively minor, there was minor damage to some buildings in the area, including partial roof damage and cracks on roads. In particular, a gas leak occurred at a middle school in Rio Tinto Dell, Humboldt County, and relevant departments quickly intervened.
