• Homes in Flood Zones Are Overvalued by Billions: Study

    Flooding is a costly and deadly natural hazard across the United States, and climate change will only make floods more frequent and more destructive. Failure to account for climate change means low-income homeowners could see their home values plunge.

  • Earthquake in Turkey Exposes Gap Between Seismic Knowledge and Action – but It Is Possible to Prepare

    The final death toll is likely to place the recent earthquake in Turkey and Syria among the worst natural disaster. The sobering question to us, as disaster mitigation scholars, is whether this enormous loss of lives, homes and livelihoods could have been avoided. There is no way to prevent an earthquake from occurring, but what can be prevented – or at least curtailed – is the scale of the calamity caused by these inevitable tremors.

  • 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.”

  • New Sodium, Aluminum Battery Aims to Integrate Renewables for Grid Resiliency

    A new battery design could help ease integration of renewable energy into the nation’s electrical grid at lower cost, using Earth-abundant metals.

  • 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.

  • Climate Change-Driven Water Crises More Severe Than Previously Thought

    The interference of climate change with the planet’s water cycle is a well established fact. New analyses suggest that in many places, runoff responds more sensitively than previously assumed.
