Major flooding risk could span decades after Chinese earthquake
Earthquake-induced landslides cause rocks and sediment to be dumped in the river valleys, and this material then moves downstream to settle on river beds; this means that river and lakes become shallower, pausing much greater risks of flooding for decades to come

This week in 1941: Galloping Gertie bridge collapses
The Tacoma Narrows bridge, known as Galloping Gertie, was a 5,000 ft-long, two-lane suspension bridge — the third longest of its kind in the world; it was the first suspension bridge to use plate girders, rather than open lattice beam trusses, to support the roadbed meaning that wind could not pass through the truss but was diverted above and below the structure; 67 years ago this week the wind was just too strong

China quake forces rethink over hazard maps
Following the Sichuan earthquake, in which more than 65,000 people died, researchers say that similar regions may also be in danger and that seismic hazard maps should be redrawn

Modified helicopters help in search and rescue missions
Researchers in Hong Kong develop a helicopter installed with a video camera and linked to the Global Positioning System (GPS), and which flies on its own on a preset course; helicopter used to survey the Sichuan earthquake area; researchers in U.K. work on a similar concept — but one which envisions using a swarm of self-coordinating helicopters

Earthquakes endanger New York more than previously believed
A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed; among other things, they say that the controversial Indian Point nuclear power plants, 24 miles north of the city, sit astride the previously unidentified intersection of two active seismic zones

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?”
