ARkStorm@Tahoe: Stakeholder perspectives on vulnerabilities and preparedness for an extreme storm event in the greater Lake Tahoe, Reno, and Carson City region
Atmospheric rivers (ARs) are strongly linked to extreme winter precipitation events in the Western U.S., accounting for 80 percent of extreme floods in the Sierra Nevada and surrounding lowlands. In 2010, the U.S. Geological Survey developed the ARkStorm extreme storm scenario for California to quantify risks from extreme winter storms and to...
Albano, Christine M.; Cox, Dale A.; Dettinger, Michael D.; Shaller, Kevin; Welborn, Toby L.; McCarthy, Maureen Design and quantification of an extreme winter storm scenario for emergency preparedness and planning exercises in California
The USGS Multihazards Project is working with numerous agencies to evaluate and plan for hazards and damages that could be caused by extreme winter storms impacting California. Atmospheric and hydrological aspects of a hypothetical storm scenario have been quantified as a basis for estimation of human, infrastructure, economic, and environmental...

Overview of the ARkStorm scenario
The U.S. Geological Survey, Multi Hazards Demonstration Project (MHDP) uses hazards science to improve resiliency of communities to natural disasters including earthquakes, tsunamis, wildfires, landslides, floods and coastal erosion. The project engages emergency planners, businesses, universities, government agencies, and others in preparing for...

SPARROW mappers are interactive tools that allow users to evaluate streamflow and nutrient and sediment conditions as well as the importance of different sources of contaminants in a selected river basin. Data can be visualized at different scales using maps and interactive graphs and tables.
The scarcity or overabundance of water presents some of the most dangerous, damaging and costly threats to human life, ecosystems and property in the form of drought, floods and debris flows.
A multiagency partnership led by the USGS and the Department of Energy seeks to shed light on lithium and other critical mineral resource potential as well as geothermal energy potential in western Nevada
In a joint blog post hosted by the Department of Energy's Office of Energy Efficiency and Rewenable Energy, DOE EERE Assistant Secretary Dan Simmons and Department of the Interior Assistant Secretary for Water and Science Tim Petty announce a new partnership for geothermal energy and critical mineral research in western Nevada.
Disasters and emergencies can happen at any time, often without warning. Natural hazards threaten thousands of lives and cause billions of dollars in damage every year throughout the nation.
Study of New Offshore Fault Mapping Related to the 1906 San Francisco Earthquake: In 2019, for the first time ever, scientists comprehensively mapped a previously overlooked offshore section of the San Andreas Fault system which may provide insight on how the fault could rupture in the future.
Earthquakes can be unsettling.
USGS Mineral Resources Program Highlights for the Summer 2020 Edition of the USGS Energy Quarterly Newsletter
For centuries, people have crossed oceans in search of valuable minerals. In recent times, though, increasing attention has been paid to the oceans themselves for their mineral potential, especially rock formations on the seafloor.
A magnitude 6.5 earthquake struck near Tonopah, Nevada, near the California-Nevada border and about 120 miles southeast of Carson City, early this morning on May 15, 2020, at 4:03 am local time (11:03:27 UTC).
U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.
