New U.S. Geological Survey (USGS) maps show areas that could be affected by Mauna Loa lava flows — information critical for response planning. Each zone identifies a segment of the volcano that could erupt lava and send flows downslope. The volcano has erupted 33 times since 1843. Typically, eruptions began in the summit caldera, with a curtain of fire (a... read more

Free and rapid imagery was provided through the USGS Hazard Data Distribution System. The calls for assistance started days before Hurricane Harvey came barreling across America’s doorstep this summer. First responders and government officials needed answers to prepare and protect communities. How strong is this storm going to be? What kind of damage occurred on its path through the Caribbean?... read more

Using a newly developed computer model called CoSMoS-COAST (Coastal Storm Modeling System – Coastal One-line Assimilated Simulation Tool), scientists predict that with limited human intervention, 31 to 67 percent of Southern California beaches may become completely eroded (up to existing coastal infrastructure or sea cliffs) by the year 2100 under scenarios of sea-level rise of one to two meters. “Beaches are... read more
