The U.S. Geological Survey (USGS) Natural Hazards Mission Area works with many partners to monitor, assess, and research a wide range of natural hazards, including earthquakes and volcanic eruptions. These efforts aim to enhance community preparedness, response, and resilience. The USGS Earthquake Hazards Program (EHP) provides earthquake monitoring and notifications, assesses seismic hazards, and conducts targeted research to reduce the risk of earthquake hazards nationwide. The USGS Volcano Hazards Program (VHP) delivers forecasts, warnings, and information about volcanic hazards based on proactive monitoring of the nation’s active volcanoes and scientific understanding of volcanic processes. The VHP also conducts targeted research on volcanic processes and creates hazards assessments that inform the level of monitoring required at each of the nation’s active volcanoes. Earthquake and volcano early warning systems are essential to disaster risk reduction: they can save lives and reduce property damage by quickly distributing messages and warnings to communities in harm’s way.
