USGS Natural Hazards

The United States Geological Survey (USGS) has a section on Natural Hazards in which it discusses how every year, natural hazards threaten lives and result in billions of dollars in damage. The USGS work with many partners to monitor, assess, and conduct targeted research on a wide range of natural hazards so that policymakers and the public have the understanding and all of the knowledge they need to enable preparedness, response, and resilience.Through the Natural Hazard programs, the USGS provides alerts and warnings of geologic hazards and supports the warning responsibilities of the National Oceanic and Atmospheric Administration (NOAA) for geomagnetic storms, tsunamis, and volcanic ash.

One part of the Natural Hazards section is the Global Seismographic Network (GSN). The GSN is a permanent digital network of seismological and geophysical sensors connected by a telecommunications network. It provides, worldwide monitoring of the Earth, with over 150 modern seismic stations distributed globally. With real-time information about the status of the GSN stations and real-time recordings, we are able to know where there is seismographic activity all over the world.
