The True Dangers of Long Trains
Trains are getting longer. Railroads are getting richer. But these “monster trains” are jumping off of tracks across America and regulators are doing little to curb the risk.Some trains stretch for 2 or even 3 miles, sometimes without regard for the delicate physics of keeping heavy, often combustible tanker cars from jumping off the tracks.

Using GSI Sensor Technology to Prediction Earthquakes
Can nuclear physics improve the prediction of earthquakes? As part of a new project which aims to provide the foundation for a reliable early warning system for earthquakes in Europe, researchers are building a network of sensors measuring radon levels and other parameters in selected water sources in Europe might be able to detect earthquakes several days in advance.

Buildings Left Sanding in Turkey Offer Design Guidance for Future Earthquake-Resilient Construction
The Feb. 6, 2023, earthquakes in Turkey and Syria put to the test advanced building technologies that can minimize damage and keep buildings functioning after a quake. Several hospitals built with one such technology – called a seismic isolation system – survived the earthquakes with almost no harm.

Why Tornadoes Are Still Hard to Forecast – Even Though Storm Predictions Are Improving
Meteorologists have gotten a lot better at forecasting the conditions that make tornadoes more likely. But predicting exactly which thunderstorms will produce a tornado and when is harder, and that’s where a lot of severe weather research is focused today.

AI Could Set a New Bar for Designing Hurricane-Resistant Buildings
Being able to withstand hurricane-force winds is the key to a long life for many buildings on the Eastern Seaboard and Gulf Coast of the U.S. Determining the right level of winds to design for is tricky business, but support from artificial intelligence may offer a simple solution.

Channeling NEXTGEN TV to Help Responders Answer the Call
A natural disaster strikes, vehicles collide on a snowy highway, a 5-alarm fire blazes through the night. For first responders, every second counts. DHS S&T is collaborating on a new effort to arm agencies with a digital alerting system that taps into NEXTGEN public TV broadcasting technologies to deliver emergency dispatches faster.

Predicting Threats to Food Security
Pests and diseases remain one of the biggest threats to food production, increasingly destabilizing food security and livelihoods across climate-vulnerable regions around the world,” says one expert. Mathematical modelling can prevent crop devastation and preserve livelihoods.

One Hurricane Is Bad Enough, but Climate Change-Driven Multiple Hurricanes Are Coming
Getting hit with one hurricane is bad enough, but new research shows that back-to-back versions may become common for many areas in coming decades. Driven by a combination of rising sea levels and climate change, destructive hurricanes and tropical storms could become far more likely to hit coastal areas in quick succession.

Why Rain on Snow in the California Mountains Worries Scientists
For much of the United States, storms with heavy rainfall can coincide with seasonal snow cover. When that happens, the resulting runoff of water can be much greater than what is produced from rain or snowmelt alone. The combination has resulted in some of the nation’s most destructive and costly floods.

High-Fidelity Simulation Offers Insight into 2013 Chelyabinsk Meteor
On the morning of Feb. 15, 2013, a small asteroid exploded over Chelyabinsk, Russia, sending a loud shockwave and sonic boom across the region, damaging buildings and leaving around 1,200 people injured. Meteoric events are natural disasters and, just like any other natural disaster, we can do more to be prepared. “They are not high-probability events, but we shouldn’t dismiss them as science fiction either,” says one scientist.

Ohio Chemical Spill Draws Focus on Railroad Dangers
The U.S. has one of the most extensive rail networks in the world, but diminishing safety standards puts people and the environment at risk. The latest accident has drawn sharp focus onto the safety standards of the highly profitable freight rail industry and its prolific lobbying against regulation.

The Train Derailment in Ohio Was a Disaster Waiting to Happen
The derailment of a freight train filled with volatile chemicals in rural Ohio earlier this month captured the headlines, but researchers and chemical spill experts say it’s a situation that plays out far too often across the country. Trains carry hazardous chemicals everyday. They’re also dangerously unregulated.

Using Drone Swarms to Fight Forest Fires
Forest fires are becoming increasingly catastrophic across the world, accelerated by climate change. Researchers are using multiple swarms of drones to tackle natural disasters like forest fires.
How Climate Change Will Affect Conflict and U.S. Military Operations
“People talk about climate change as a threat multiplier,” said Karen Sudkamp, an associate director of the Infrastructure, Immigration, and Security Operations Program within the RAND Homeland Security Research Division. “But at what point do we need to start talking about the threat multiplier actually becoming a significant threat all its own?”
