Volcano Hazards Assessments Help Mitigate Disasters

The Volcano Hazards Program develops long-range volcano hazards assessments. These includes a summary of the specific hazards, their impact areas, and a map showing ground-hazard zones. The assessments are also critical for planning long-term land-use and effective emergency-response measures, especially when a volcano begins to show signs of unrest.

RARMI: Northern Rocky Mountain Science Center (NOROCK) Apex Sites

In contrast to RARMI study areas in Colorado that have 10 or more years of records of continuous population monitoring, there are fewer long-term datasets for amphibian populations in the northern Rocky Mountains. The exception is an ongoing study of Columbia spotted frogs at Lodge Creek, Yellowstone National Park. Three other long-term research and monitoring areas have been established in...

RARMI: Fort Collins Science Center (FORT) Apex Sites

FORT is monitoring populations of amphibians at three apex sites using capture-recapture methods. Our goal in monitoring populations is to detect fluctuations in population size, sex ratio, survival, and recruitment. Through long-term monitoring, we can also address breeding phenology in relation to elevation, weather, and climate. Other specific questions can be asked about issues such as...

COMPLETED: Using thermal imagery to assess wolf hairloss from sarcoptic mange

Researchers at NOROCK and their partners used thermal cameras at the Grizzly and Wolf Discovery Center in Montana to assess the amount of heat lost under a range of environmental conditions with and without hair. These methods help scientists better understand how mange operates in wild wolves throughout the Greater...

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.

Metapopulation Dynamics of the Adélie Penguin

The Oregon Cooperative Unit, graduate students, and a group of U.S. and international collaborators are conducting long-term research on the Adélie penguin on Ross Island, Antarctica. This species depends on sea ice (obligate) and in some regions of Antarctica is being affected by climate change’s influence on sea ice patterns.

Kitsap Groundwater Model

The Issue: Groundwater provides a major source of drinking water for the population of the Kitsap Peninsula. Consequently, as the population grows, so does the demand for groundwater. However, the quantity of usable groundwater is limited, largely because the Peninsula is bounded by seawater and the potential for water-level declines and seawater intrusion increases as groundwater usage...

Raging River Temperature

The Issue: Large, in-channel wood that helps to create and maintain healthy aquatic habitat in rivers throughout the Pacific Northwest was removed from many rivers in the past. In 2009, King County put wood back into the river to restore the Raging River watershed. To guide the county's restoration of the Raging River watershed, managers need to know the effect of restoration...

Lake Spokane

The Issue: Phosphorus from many different sources has caused water quality problems for Lake Spokane in eastern Washington by promoting the growth of algae and aquatic plants. Phosphorus comes from municipal and industrial point-sources upstream of Lake Spokane, as well as non-point sources like septic tanks, agricultural fields, and wildlife. Lake Spokane was listed by the...

South Fork Nooksack River Basin Groundwater and Surface-water Interactions and Processes

High water temperatures and low instream flows during the summer have been identified as some of the key limitations for the viability of South Fork Nooksack River salmon populations including summer and spring-run Chinook salmon. Restoration strategies including the placement of engineered log jams, the restoration of floodplains and wetlands, and instream flow negotiation have been developed...

Crater Lake Image Shows Potential of Sentinel-2A

This image from the European Space Agency's Sentinel-2A satellite offers a breathtaking view of Crater Lake National Park in southern Oregon. It offers something equally important to park managers, scientists, and anyone else interested in land cover change—a view that is highly similar and complementary to Landsat acquisitions.

Mount St. Helens earthquake record during times of magma recharge.

The top plot is the number of located earthquakes per week from the Pacific Northwest Seismic Network's catalog. The bottom plot shows the earthquake depths with time. Earthquakes are plotted as circles with the size of the circle corresponding to the magnitude of the earthquake (see legend). Both plots show the time period from 1987 to September 2004, and 2008 to May 4

USGS-CVO crew digs out Mount St. Helens' Sep. Lobe monitoring station.

During the first few days of Mount St. Helen's earthquake swarm in March 2016, the September Lobe monitoring station (located on the 1980-86 dome) was buried in deep snow and not transmitting data. USGS-Cascades Volcano Observatory Technicians Kelly Swinford and Amberlee Darold dug out the station on March 30, restoring data flow and improving our ability to monitor the
