New USGS-FEMA study highlights economic earthquake risk in the United States
Natural Hazards Mission Area
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.
Reducing Risk
Reducing Risk
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.
Subduction Zone Science
Subduction Zone Science
The most powerful earthquakes, tsunamis, landslides, and volcanic eruptions occur in subduction zones, where two plates collide and one is thrust beneath another.

Aftershock forecasting
Aftershocks can compound the impacts of a major earthquake, disrupting recovery efforts and potentially further damaging weakened buildings and infrastructure. Forecasts of the probability of aftershocks can therefore aid decision-making during earthquake response and recovery. Several countries issue authoritative aftershock forecasts. Most aftershock forecasts are based on simple statistical
Global variability of the composition and temperature at the 410-km discontinuity from receiver function analysis of dense arrays
Seismic boundaries caused by phase transitions between olivine polymorphs in Earth's mantle provide thermal and compositional markers that inform mantle dynamics. Seismic studies of the mantle transition zone often use either global averaging with sparse arrays or regional sampling from a single dense array. The intermediate approach of this study utilizes many densely spaced seismic arrays distri
Relatively stable pressure effects and time-increasing thermal contraction control Heber geothermal field deformation
Due to geological complexities and observational gaps, it is challenging to identify the governing physical processes of geothermal field deformation including ground subsidence and earthquakes. In the west and east regions of the Heber Geothermal Field (HGF), decade-long subsidence was occurring despite injection of heat-depleted brines, along with transient reversals between uplift and subsidenc

Landslide Basics
Landslides occur in all 50 states and territories and they affect lives, property, infrastructure, and the environment. Understanding when, where, and how landslides occur can help to reduce the risk of living with these natural hazards.
Post-Fire Hazards Impacts to Resources and Ecosystems (PHIRE): Support for Response, Recovery, and Mitigation
The Post-Fire Hazards Impacts to Resources and Ecosystems (PHIRE) project provides science to characterize climate-amplified, uncharacteristic patterns of wildfire disturbance and post-fire ecosystem recovery and enhance prediction of environmental impacts and post-fire hazards.
