Stoking Wildfire Resilience in Oregon
Monitoring allows all the moving pieces of an emergency response to launch into action and for decision makers to have as much time as possible to assess and mitigate the threat. This is certainly true when it comes to wildfires. S&T is piloting smoke detection sensors ahead of the 2023 wildfire season.

Mitigating the Impact of Extreme Weather and Climate Uncertainty on Reservoirs
Abrupt weather extremes, changing climate and frequent natural hazards such as floods and droughts create challenges for our nation’s aging reservoir systems. Researchers are working to help mitigate these problems.

More Places to Experience Floods as Extreme Weather Events Become More Frequent and Intensify
As extreme weather events become more frequent and intensify, the number of people and places exposed to flooding events is likely to grow. But until now, surprisingly little was known about how floodplain development patterns vary across communities.

U.S., China Compete for Africa's Rare Earth Minerals
African countries like the Democratic Republic of Congo have some of the largest deposits of these resources, but China currently dominates the supply chain as well as their refinement and the U.S. wants to reduce its reliance on the Asian giant.

Tidal Stream Power Can Significantly Enhance Energy Security
A new study reveals the potential of tidal resources to make a marked difference on a community’s clean energy ambitions. Using tidal technologies as part of a renewable energy mix can also reduce the space required for power-generating facilities, both on land and at sea, by around 33% and significantly reduce their visual impact since much of their operation is below the sea’s surface.

Floods, Rising Sea Levels Push Planned Internal Migration
Climate change could force billions to move by the end of the century, displaced by floods and rising sea levels. Some communities are already adapting through managed retreat and moving people to other areas.

Earthquake Footage Shows Turkey’s Buildings Collapsing Like Pancakes. An Expert Explains Why
Many of the collapsed buildings appear to have been built from concrete without adequate seismic reinforcement. Seismic building codes in this region suggest these buildings should be able to sustain strong earthquakes (where the ground accelerates by 30% to 40% of the normal gravity) without incurring this type of complete failure. The 7.8 and 7.5 earthquakes appear to have caused shaking in the range of 20 to 50% of gravity. A proportion of these buildings thus failed at shaking intensities lower than the “design code.”

Gauging Losses and Lessons in Turkey's Unfolding Earthquake Calamity
As earthquake engineers stress, most of the time, buildings kill people, not the shaking itself. Many of the buildings destroyed in the quake had “soft floors” – ground-level retail spaces with very little reinforcement supporting far heavier residential floors above; buildings where, for tax purposes, higher floors jutted out beyond the dimensions of the ground floor; or homes where floors were added as families expanded. Engineers call such structures “rubble in waiting.”

Powering the Nation: How to Fix the Transformer Shortage
America’s electric grid relies on transformers — electrical components that convert voltage, enabling power distribution to homes and businesses. Disruptions to transformer operations, such as natural disasters, extreme weather, or cyber/physical attacks, cause substantial economic damage. Securing the transformer supply chain is critical to ensure resilience, expand renewable power, and strengthen grid safety. To mitigate potential disruptions, Congress should spur the supply of transformers by investing in domestic transformer manufacturing and workforce development.

Supporting Dams with Innovative Materials
There are about 91,000 dams in the United States. About half the dams built in the past century and a half are starting to show their age, with resulting wear and tear. Severe weather events, extreme temperatures, erosion and rising water levels are all straining the infrastructure and exacerbating the impacts of deterioration and aging processes. In many cases, simply replacing the dams and levees is not a viable option due to high costs.

Extremist Couple Charged in Plot to Destroy Baltimore’s Power Grid
Two extremists have been charged Monday with conspiracy to attack and destroy energy facilities around Baltimore in a plot to “completely destroy” the city. The man, the founder of the neo-Nazi group Atomwaffen, and his accomplice appear to be part of trend among domestic violent extremists to target the U.S. electrical grid. In recent years, DHS and the FBI have discovered several such conspiracies to take down the power system, with the most recent attacks taking place in North Carolina and Washington State.

Creating Buildings That Can Withstand the Most Extreme Stress Loads
Combined ballistic impacts pose a major challenge for engineers who build structures that must withstand extreme stresses. An explosion can hurtle fragments and debris at enormous velocities so they strike the surroundings. Then comes the shock wave. It’s a scary combination.

Western Wildfires Destroyed 246% More Homes and Buildings Over the Past Decade
It can be tempting to think that the recent wildfire disasters in communities across the West were unlucky, one-off events, but evidence is accumulating that points to a trend. In nearly every Western state, more homes and buildings were destroyed by wildfire over the past decade than the decade before, revealing increasing vulnerability to wildfire disasters.

Water Wars: A Historic Agreement Between Mexico and US Is Ramping Up Border Tension
As climate change drives rising temperatures and changes in rainfall, Mexico and the US are in the middle of a conflict over water, putting an additional strain on their relationship. Partly due to constant droughts, Mexico has struggled to maintain its water deliveries for much of the last 25 years, deliveries to which it is obligated by a 1944 water-sharing agreement between the two countries.
