Sensors that detect changes in atmospheric pressure due to ground shaking can also obtain data about large earthquakes and explosions that exceed the upper limit of many seismometers, according to new research. The sensors, which detect inaudible infrasounds carried through the air, could improve tsunami warnings and other emergency responses while also lowering costs. Research […]
A new project will make it possible for scientists to better track a suite of phenomena in Alaska ranging from earthquakes to wildfires to sea ice. The five-year, $6.9 million project funded by the National Science Foundation will enhance measurements of Arctic change across western and northern Alaska. It’s led by the Alaska Earthquake Center, […]
PANORAMA MOUNTAIN — “For some reason, when I come to this terrain, I know something’s been pulverized.” Cole Richards says this while watching three companions kick their steps Chilkoot-Pass style into an abrupt hill.

Just how noisy is the ocean? Quiet enough to hear a pin drop or so noisy you can barely hear the person next to you? NOAA is now undertaking a novel effort to answer these questions. In 2014 NOAA began establishing its first-ever coordinated Ocean Noise Reference Station Network—a set of 10 undersea listening stations […]
