When transportation officials consider a construction project, they typically drill into the ground to determine the composition of the earth beneath the work site. The information gleaned from those tests helps determine the design or repair requirements, but it’s an imperfect science, as the results can contain information gaps due to differing conditions between drilling locations—even if they’re just feet apart.

In Arkansas, officials address that problem by using non-invasive seismic imaging—a so-called “ultrasound for roads” that uses existing technology to help highway planners more accurately map the subsurface. The project, a research partnership between the Arkansas Department of Transportation (ARDOT) and the University of Arkansas, aims to help road projects stay on schedule and on budget by providing detailed information without the need for exploratory drilling.

Over the next week, Southern California has only a 27% chance of experiencing a third earthquake greater than magnitude 6, but a 96% chance of going through a tremor of magnitude 5 or higher.

Those precise probabilities were generated by scientists at the United States Geological Survey (USGS), using models based on longstanding principles of seismic behavior and decades of data on aftershocks from earthquakes.

RIDGECREST, Calif. — Crews in Southern California assessed damage to cracked and burned buildings, broken roads, leaking water and gas lines and other infrastructure Saturday after the largest earthquake the region has seen in nearly 20 years jolted an area from Sacramento to Las Vegas to Mexico.

No fatalities or major injuries were reported after Friday night’s 7.1-magnitude earthquake. But warnings by seismologists that large aftershocks were expected to continue for days — if not weeks — prompted further precautions.

(TNS) - For the second consecutive day, a major earthquake shook Southern California and was felt far beyond, stopping the NBA’s Summer League games in Las Vegas, forcing the evacuation of rides at Disneyland in Anaheim, and reminding residents that the state is always on unstable ground and destined for more.

It registered a magnitude of 7.1 on Friday night and was the strongest earthquake to hit the state in two decades, causing fires in the small town of Ridgecrest (population 29,000), and sending shock waves felt more than 300 miles away in all directions – Sacramento, Phoenix, Mexico.

The state agency in charge of earthquake study and preparation, as well as monitoring mining efforts in Oregon, could be shut down after going over budget for the second time in four years.

The Oregonian/OregonLive reports the Department of Geology and Mineral Industries, widely known as DOGAMI, will lose three staff members and the Governor’s office is considering whether the agency should continue to exist in its current form given its financial issues.

Deepfake videos are hard for untrained eyes to detect because they can be quite realistic. Whether used as personal weapons of revenge, to manipulate financial markets or to destabilize international relations, videos depicting people doing and saying things they never did or said are a fundamental threat to the longstanding idea that “seeing is believing.” Not anymore.

Most deepfakes are made by showing a computer algorithm many images of a person, and then having it use what it saw to generate new face images. At the same time, their voice is synthesized, so it both looks and sounds like the person has said something new.

(TNS) — After battling the most destructive wildfires in California’s history over the past two years, Cal Fire is rolling out emergency fuel reduction projects to help protect the state’s most vulnerable communities.

The 35 projects span the state, from Siskiyou to San Diego counties. One crucial effort in the Sacramento area, the North Fork American River Shaded Fuel Break, is a fuel break project that covers 850 acres around the city of Colfax in Placer County.

A fuel break is an area of land where vegetation has been transformed to make fires more controllable, Cal Fire officials told reporters Thursday at the Colfax project site. Methods involve chipping and prescribed burning.

While there are “huge opportunities” on the horizon for the cyber insurance industry, cyber insurance underwriters still face the challenge of not having enough historical data to work with.

“It’s really scary to underwrite something when you just don’t know what the potential losses could be,” said Brian Meredith, managing director at UBS Group AG, during a panel discussion on trends in the property/casualty insurance sector at S&P’s 2019 Global Insurance Conference in New York. “There’s lots of opportunity here, but we need a lot more data to expand it.”

The U.S. Geological Survey a magnitude 5.5 earthquake has hit near the Pacific coast of Northern California.

The agency says the earthquake struck at 8:53 p.m. on Saturday at a spot 17.3 miles southwest of Scotia, a town of 850 people.

California Gov. Gavin Newsom is pressing lawmakers on a wildfire fund that may be financed through bonds to help utilities pay for the catastrophic blazes their power lines keep igniting, according to people familiar with the proposal.

Newsom is proposing a so-called liquidity fund that could be seeded by at least $10 billion in Department of Water Resources bonds, said the people, who asked not to be named because the discussions are private. The administration may also ask utilities to contribute about $7.5 billion in equity, the people said.
