• Accurately Predicting Impact of Storms, Sea-Level Rise on Coasts

    The combination of extreme storms and rises in sea levels as a result of global climate change are posing serious threats to coastal communities. The Forecasting Coastal Evolution (ForCE) model has the potential to be a game-changing advance in coastal evolution science.

  • U.S. Freight Railroads Bolstered Supply Chain Resilience during Pandemic

    Despite the particularly volatile, pandemic-driven period, railroads met consumers’ and businesses’ unexpected surge of demands, reliably delivering goods such as agricultural products, personal protective equipment and online retail merchandise and ultimately highlighting the rail industry’s role as an essential component of the U.S. economy.

  • Producing Geothermal Energy Diminishes Earthquake Risk

    Researchers studying the 5 July 2019 magnitude-7.1 earthquake in Ridgecrest, California found that none of the thousands recorded aftershocks in the region were seen in the Coso geothermal field, an area only about ten kilometers away. Now they know why: The development of geothermal energy reduces underground stress and mitigates risks of large earthquakes.

  • Are Buyouts a Viable Tool for Climate Adaptation?

    Sea level rise, and the resulting storm surges and floods, have made managed coastal retreat – the purposeful movement of people, buildings, and other infrastructure away from the coast – an option which more and more communities are considering. The need for adaptive solutions to the growing coastal challenges is clear, but questions remain as to where buyouts by the government of vacated property can and should fit in.

  • Ransomware Cyberattack Hits Hundreds of U.S. Businesses

    U.S. IT company Kaseya urged its customers to shut down their servers after hackers smuggled ransomware onto its network. Such attacks infiltrate widely used software and demand ransom to regain access. The REvil gang, a major Russian-speaking ransomware syndicate, appears to be behind the attack.

  • Florida Condo Collapse – Searching for Answers about What Went Wrong in Surfside Can Improve Building Regulation

    How does a building stand for 40 years and then collapse, perhaps with little or no warning? Why did it collapse so that part of the building stayed up, sparing many lives? It might take months or longer for engineers to find answers to these questions. But those reports, when they do come, are important because engineers can use them to improve building codes and other safety measures – and hopefully prevent future collapses.

  • Supply Chains Have a Cyber Problem

    If it wasn’t clear before the cyberattacks on, JBS S.A. and Colonial Pipeline, it’s now painfully clear that the intersection of cyberattacks and supply chains creates a wicked new form of risk—and the stakes are as much about national security as they are economics.

  • For Flood-Prone Cities, Seawalls Raise as Many Questions as They Answer

    The U.S. Army Corps of Engineers, whose mission includes maintaining waterways and reducing disaster risks, has recently proposed building large and expensive seawalls to protect a number of U.S. cities, neighborhoods and shorelines from coastal storms and rising seas. As a scientist who studies the evolution and development of coastlines and the impacts of sea level rise, I believe that large-scale seawalls, which cost billions of dollars to build, are almost certainly a short-term strategy that will protect only a few cities, and will protect only selected portions of those cities effectively.

  • Why Did the Miami Apartment Building Collapse? And Are Others in Danger?

    It is too early to tell what caused the collapse of the Champlain Towers South Tower, but the following causes are now being examined: a progressive collapse as a result of a failure of a primary structural element, which then causes failure of adjoining members; the building was constructed on reclaimed wetlands, which may have been sinking; there was also construction work ongoing nearby, which could have disturbed the foundations; if there was a reduction in the capacity of the soil to support these loads, such as in the event of a sinkhole, there would be nothing underpinning the building.

  • Military and Defense-Related Supply Chains

    The military services, geographic combatant commanders, the Defense Logistics Agency (DLA), and other combat support agencies have different responsibilities and incentives, and their management of their supply chains reflect these differences. These incentives drive behavior that makes individual sense for the organizations, but might not result in overall effectiveness in supporting the needs of operating forces.

  • A Simple Simulation Helps Coastal Towns Plan for Rising Sea Levels

    Climate change causes sea level rise and increasingly strong coastal storms. Knowing how water moves through coastal structures can yield important insights for residents and planners.

  • Making Our Computers More Secure

    Corporations and governments rely on computers and the internet to run everything, but security hacks just this past month —  including the Colonial Pipeline security breach and the JBS Foods ransomware attacks  — demonstrated, yet again, how vulnerable these systems are. Researchers presented new systems to make computers safer.

  • Natural Hazards Threaten 57% of U.S. Structures

    As a result of increasing temperatures and environmental changes, more than half of the structures in the contiguous United States are exposed to potentially devastating natural hazards—such as floods, tornadoes, hurricanes, and wildfires.

  • Role of Managed Retreat as a Climate Change Response

    Managed retreat—the climate adaptation response of moving people and property out of harm’s way— is becomig more appealing as one of several responses to sea-level rise. Researchers explore what it would take for managed retreat to be supportive of people and their priorities. The key is to consider retreat alongside other responses like coastal defenses, and not just as an option of last resort.

  • “Managed Retreat” Can Reinvent Cities While Protecting Lives When Climate Change Floods, Burns or Bakes the Land

    Record-breaking heat waves; megadroughts, drying fresh-water sources; hotter and more frequent wildfires; intensifying hurricanes — this is what climate change looks like, and communities need to be prepared. Sometimes small adaptations can help reduce the heat or minimize the damage. But when the risks get too high, one strategy that has to be considered is managed retreat – the purposeful movement of people, buildings and other infrastructure away from highly hazardous places.
