Fire Ecology

Ecosystems throughout the western U.S. are often dependent on a particular fire regime to reduce hazardous fuels and rejuvenate forests or even guide evolution of plant life and regulate ecological communities. Today fire’s role is more complicated. For example, fire can favor invasive plants and these invaders may, in turn, alter the fire regime.

Earthquake Early Warning (EEW)

An existing technological capability (not yet implemented in CA) for providing a few seconds of advance notification before arrival of earthquake-generated seismic waves causing ground shaking, with current efforts underway to move forward with providing users with the means to utilize the system for warning and preparedness action plans.

Debris Flow and Wildfire Evacuation Messaging

What persuades someone to heed a debris flow or wildfire evacuation warning? SAFRR partners in emergency management are especially interested in the results of this study, now underway with Columbia's Center for Research on Environmental Decisions.

Change and Disturbances

Organisms have different abilities to adapt to disturbances. Some disturbances can be catastrophic to one species and inconsequential to another. Our Forest and Rangeland Ecosystem Science Center (FRESC) scientists are studying the effects of disturbances on species, biogeochemistry, water quality, habitat connectivity and landscape patterns.

Cascades Volcano Observatory (CVO)

The CVO staff conduct research on many aspects of active volcanism, respond to dangerous volcanic activity in many parts of the world, and maintain a close watch over volcanoes in Washington, Oregon and Idaho. The USGS established CVO in Vancouver, Washington, after the May 18, 1980, eruption of Mount St. Helens.

ARkStorm Scenario

A modeled scenario of U.S. West Coast winter storm events induced by the formation of Atmospheric Rivers (AR) and capable of causing massive and devastating flooding.

Alaska Volcano Observatory (AVO)

The AVO is a partnership among the USGS, the Geophysical Institute of the University of Alaska Fairbanks, and the Alaska Division of Geological and Geophysical Surveys. To mitigate volcanic hazards, AVO monitors and studies Alaska's hazardous volcanoes to forecast and record eruptive activity. AVO also monitors volcanic activity in the Commonwealth of the Northern Mariana Islands.

A Hub for Planetary Research

The USGS Astrogeology Science Center is a hub for planetary research. The center provides guest facilities, labs, and numerous cartographic resources for both the scientific community and the general public. Geologists, archivists, data specialists, and cartographers are employed at the center to assist the planetary science community.
