Every year in the United States, natural hazards threaten lives and livelihoods and result in billions of dollars in damage. We 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 they need to enhance preparedness, response, and resilience.
USGS scientists develop new products to make science available to the public, emergency managers, and decision-makers. These efforts increase public safety and reduce risk and economic losses caused by natural hazards.
The most powerful earthquakes, tsunamis, landslides, and volcanic eruptions occur in subduction zones, where two plates collide and one is thrust beneath another.
