Numerical Models of the Physics Underpinning Induced Earthquakes

The USGS uses computer simulations to evaluate the physical relationships between fluid injection (or extraction) and earthquakes. We can only indirectly study these relationships using observations, so computer simulations help us gain a better physical understanding for the processes that are most likely causing these earthquakes. Scientists can also use such simulations to understand...

Observational Studies of Induced Earthquakes

In response to sudden changes in seismicity that are potentially induced by human activity, the USGS may deploy temporary seismic stations to better understand the earthquakes. These deployments typically consist of 2-15 seismometers placed in the immediate vicinity of the seismicity.

DETAILED AQUIFER MAPPING OF THE SPRINGVILLE, N.Y. AREA Erie, Cattaraugus, and Wyoming Counties, New York

Introduction Public-water systems at Springville and Yorkshire/Delavan, N.Y. along Cattaraugus Creek draw from local groundwater resources and serve about 5,500 people (U.S. EPA SDWIS database). The remainder of the population obtains water from domestic wells, many of them completed in glacial aquifers. A Cattaraugus Creek tributary valley (Buttermilk Creek) to the south is the site of the...

DETAILED AQUIFER MAPPING OF THE MALONE, N.Y. AREA (Adirondack foothills and St. Lawrence lowlands transect) Franklin County, New York

Introduction The Village of Malone, Franklin County, New York is located along the Salmon River where it exits the northern foothills of the Adirondack Mountains and flows northward across the St. Lawrence Lowlands until its confluence with the St. Lawrence River. The public water supply of the Village of Malone serves a population of 13,200 (U.S. EPA SDWIS database), which includes three...

MD-DE-DC WSC Surface Water Capabilities

As an integrated part of the WSC, the Surface Water Team monitors and conducts investigative research to describe and improve our region's understanding of extreme hydrologic events - droughts, floods and flood hazards, and coastal or bay storm surge and inundation. They also facilitate measurement stream stages, streamflow, and computes daily streamflow at locations in Maryland, Delaware, and...

Characterization of Streamflow, Suspended Sediment, and Nutrients in the Upper Yampa River Basin

The Upper Yampa River Basin (UYRB) drains approximately 1,800 square miles west of the Continental Divide in northwestern Colorado. In 2019, the USGS, in cooperation with local stakeholders in the UYRB water community, initiated a study to characterize streamflow, suspended sediment, and nutrients using historic and recently acquired water-quality data from a long-term monitoring program...

Denali National Park Geohazards Geologic Mapping

Denali National Park (DENA) is a major draw for tourism and recreation and a major economic engine for central Alaska. However, the geologic forces that created the steep landscape of DENA also make it prone to geologic hazards (geohazards) like landslides, debris flows, and earthquakes. DENA has only one major road, called the ‘Park Road’, that serves nearly all of its infrastructure.
