Figures showing California has slowed the rate of coronavirus infections may be in doubt because a technical problem has delayed reporting of test results, the state’s top health official said.

For days, California hasn’t received full counts on the number of tests conducted nor the number that come back positive for COVID-19, Health and Human Services Secretary Dr. Mark Ghaly said Tuesday.

A wildfire in mountains east of Los Angeles that has forced thousands of people from their homes was sparked by a malfunctioning diesel vehicle, fire officials said Monday.

The vehicle spewed burning carbon from its exhaust system, igniting several fires Friday on Oak Glen Road in Cherry Valley, and authorities were asking anyone who may have seen such a vehicle at the time to contact investigators, according to a statement from the California Department of Forestry and Fire Protection.

The blaze in Riverside County, among several wildfires across California, had consumed nearly 42 square miles of dry brush and chaparral since it broke out Friday evening, fire officials said.

California’s attorney general and state and local agencies are investigating whether Amazon.com Inc. has taken adequate steps to protect its workers from the coronavirus pandemic, according to a court filing on Monday.

Attorney General Xavier Becerra’s office, California’s Division of Occupational Safety and Health and the San Francisco Department of Public Health “have all opened investigations into Amazon’s practices” around the pandemic, San Francisco Superior Court Judge Ethan Schulman wrote in the filing.

A wildfire in rural central California grew larger but firefighters also increased containment, authorities said.

Low humidity and hot temperatures have raised fire danger in large portions of the state.

The Mineral Fire in western Fresno County expanded to more than 28,500 acres and was 62% contained.

Get ready for the big one.

That’s a refrain Californians have heard for years, but this time one scientist is putting a number on it.

There’s a 1% chance a big quake will strike next year on the Southern section of the San Andreas Fault, according to Ross S. Stein, Ph.D., CEO of Temblor Inc., a catastrophe risk modeling company based in Redwood City, Calif.

That may not sound that high, but it’s a lot higher than previously believed.

New findings point to need for home improvements that resist embers, the cause of up to 90 percent of wildfire ignitions

(TNS) - From Corcoran and Avenal state prisons in the arid Central Valley to historical San Quentin on the San Francisco Bay, California prisons have emerged as raging COVID-19 hot spots, even as the state annually spends more on inmate health care than other big states spend on their entire prison systems.

The new state budget taking effect July 1 authorizes $13.1 billion for California’s 34 prisons, housing 114,000 inmates, more than three times what any other state spends. That sum includes $3.6 billion for medical and dental services and mental health care — roughly what Texas spends to run its entire 140,000-inmate prison system.

In the Listos California Campaign for preparedness, the Governor’s Office of Emergency Services (Cal OES) set out to reach a million within the state with preparedness training and messages. Those numbers will be released by the governor’s office next week.

But as that campaign was underway, the coronavirus pandemic hit, forcing a reorganization and creating opportunity. In March, the approach to training and preparedness — typically training in small groups such as a social club or a church group — transitioned online.

California has adopted new workplace safety standards to protect agricultural employees who work at night.
