The Plumas County Office of Emergency Services is reporting moderate damage to at least three homes near the epicenter of Thursday night’s 5.7 earthquake on the east shore of Lake Almanor.
The quake, which struck near Canyon Dam, was felt over a wide swath of California and Nevada, from the Bay Area north to Oregon and has triggered more than 120 aftershocks of magnitude 1.0 or larger.
According to Plumas County OES there have been no reports of injuries due to the earthquake and no reports of damage or concerns at critical facilities such as hospitals or communications infrastructure.
Plumas OES Director Jerry Sipe said that PG&E’s dam assessment was completed earlier this morning and no problems or concerns with dam safety were identified.
The Lake Almanor Mutual Water Company sustained a water main rupture, emptying the tank. Up to 1,500 customers may be affected. Repairs are anticipated to be complete by noon today. State Public Health officials anticipate a boil water advisory will be issued until disinfection and testing shows the system is free of contamination.
600 PG&E customers on the Lake Almanor who had power interrupted by the quake have had their power restored this morning.
At least 3 homes on the eastshore and Lake Almanor peninsula, said Sipes, sustained moderate damage. Damage consists of collapsed chimneys and masonry, drywall and plaster cracking. No structural damage has been reported at this time. This is an area with many vacant and seasonal homes, so not all damage may be fully known at this time.
The 5.7 shaker also triggered a relatively minor rock slide on Highway 89 and a fews miles north of Hwy 147. No other reports of roadway issues have been reported. Highway 89 remains open at this time.
Here in Lassen County the Office of Emergency Services reports that no injuries were sustained and no damage to critical infrastructure.
Lassen OES Chief Eric Ewing said that residents in Westwood reported minor damage to a chimney as well as items knocked from shelves.
