WIFIRE Lab Forms New Partnership with DHS
For the past 10 years, the WIFIRE team at the San Diego Supercomputer Center (SDSC) at UC San Diego has been focused on meeting the growing needs of hazard monitoring, mitigation and response. Most recently, the team has partnered with DHS to integrate edge computing – a strategy emphasizing data collection and analysis at the site of or geographically near data sources. Joint effort aims to demonstrate workflows utilizing edge computing for wildfire monitoring, response and mitigation.

The Causes of the 1931 Yangtze River Deluge
In the summer of 1931, an unprecedented calamity unfolded along the Yangtze River basin in eastern China—the 1931 Yangtze River flood, known as one of history’s deadliest natural disasters. This cataclysmic event submerged a staggering 180,000 km2, affected 25 million lives, and claimed over 2 million lives. What caused this monumental flood?

Watching Trends: Helping the NRC Model Risk and Reliability
Nuclear power accounts for 0.03 deaths per terawatt-hour of electricity generated, when including both accidents and deaths due to air pollution. This fatality rate is a factor of 820 lower than electricity produced using coal. One reason U.S. nuclear power plants have such an impressive safety record is that utilities embrace a safety culture, one that uses probabilistic risk assessments, also known as PRAs.

Shutting Off Power to Reduce Wildfire Risk on Windy Days Isn’t a Simple Decision – an Energy Expert Explains the Trade-Offs Electric Utilities Face
Maui County is suing Hawaiian Electric, claiming the utility was negligent for not shutting off power as strong winds hit the island in the hours before the city of Lahaina burned. Electricity is critical infrastructure and a foundational bedrock to many other services, so utilities have to balance the risk of keeping power on with the risks created by shutting power off.

How Much Wave Energy Is in Our Oceans?
The ocean is never still, but exactly how much energy surges through our ocean waves is a matter of debate. That uncertainty makes it challenging for countries to weave wave energy into their future climate goals. New study could help countries better estimate how much power their waters carry.

A Tropical Storm in California? Warmer Waters and El Niño Made It Possible.
Tropical Storm Hilary made landfall in Mexico and crossed into California last weekend, knocking out power and drenching wide swaths of southern California. Los Angeles received 2.48 inches of rain on Sunday, breaking a single-day record from 1906 of 0.03 inches. Storm Hilary adds to the lengthy list of climate-fueled disasters this summer.

Sediment Movement During Hurricane Harvey Could Negatively Impact Future Flooding
Enormous amounts of sediment, or sand and mud, flowed through Houston waterways during Hurricane Harvey in 2017, due in part to modifications made by humans to bayous, rivers and streams over the past century. Harvey was the largest rainfall event in U.S. history, and it moved 27 million cubic meters of sediment, or 16 Astrodomes, through Houston waterways and reservoirs. This could seriously impact future flooding events and be costly to the City of Houston.

Thermal Battery Helps Industry Eliminate Fossil Fuels
The explosion of renewable energy projects around the globe is leading to a saturation problem. As more renewable power contributes to the grid, the value of electricity is plummeting during the times of day when wind and solar hit peak productivity. The problem is limiting renewable energy investments in some of the sunniest and windiest places in the world. Antora Energy is commercializing a thermal battery that lets manufacturers use renewable energy around the clock.

Emerging Threats to the U.S. Financial System
In early 2021, a freewheeling, freethinking group of investors on Reddit plowed their money into GameStop, a video game retailer that several big hedge funds had bet against. The stock price shot up, some people made millions—and, to the delight of those on Reddit, the hedge funds had some very bad days. Researchers saw the GameStop story as a cautionary tale. If investors on Reddit could work together to move the markets like that, what could an adversary like China do?
