Earthquake Early Warning: Vital for City Transit

Although no one can reliably predict earthquakes, today’s technology is advanced enough to rapidly detect seismic waves as an earthquake begins, calculate the maximum expected shaking, and send alerts to surrounding areas before damage can occur. This technology is known as “earthquake early warning” (EEW).

The Vital Nature of Streamgaging

Gary Moore spent the last three days of 2015 stacking hefty bags of sand in front of a fellow church member’s brick home. With only 1,000 feet between the house and the swelling Mississippi and Meramec Rivers, Moore and other volunteers worked quickly, in frigid temperatures, to assemble a 10-foot high, 1,000-foot-long sandbag wall to ward off floodwaters.

Tracking the Bad Guys: Toxic Algal Blooms

Every few days, a fleet of satellites orbiting 700 kilometers above the Earth scans the continental United States to help keep Americans safe. But these eyes in the sky aren’t seeking terrorists or enemy combatants: they scrutinize lakes to locate problems of the microbial variety, namely cyanobacteria.

Landsat Eyes Help Guard the World’s Forests

“We’re seeing the loss of forests in many places,” said Matthew Hansen, a professor at the University of Maryland. “Dynamics include increasing tropical deforestation, more frequent and severe boreal forest fires, disease in temperate forests and the commoditization of subtropical forests.”

Preparing for the Storm: Predicting Where Our Coasts Are at Risk

Living in the Outer Banks means living with the power of the sea. Jutting out from North Carolina’s coast into the Atlantic Ocean, this series of sandy barrier islands is particularly vulnerable to damage from major storms. In April 2016, another nor’easter was set to strike, but this time, Dare County officials were approached by their local weather forecaster with a new kind of prediction....
