Washington, DC – Wednesday, the U.S. Senate Committee on Commerce, Science, and Transportation favorably reported U.S. Senator Lisa Murkowski’s (R-AK) National Landslide Preparedness Reauthorization Act on a strong bipartisan basis. Murkowski’s bill, cosponsored by U.S. Senator Maria Cantwell (D-WA), would reauthorize current law for ten years, through Fiscal Year (FY) 2034, and provide the U.S. […]
Earthquakes have a well-known and easily recognizable connection to volcanoes. The sudden onset of ground shaking can indicate near-term or imminent volcanic activity. Volcanic tremors, however, are difficult to detect. These are semi-continuous seismic or acoustic signals, or both, that continue for just a few seconds or persist for a year or more. They, like earthquakes, carry […]

Using a metal pole that was part of a boat frame, together they lugged a four-stroke outboard motor that seemed to float above the wet greenery. The three men were scientists who […]
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 […]
