Remote Sensing of Energy Development

Oil and gas development across the western United States has increased substantially in recent decades, including within the Colorado Plateau. The Colorado Plateau is a high desert region of grasslands, shrublands, and woodlands and is home to a large number of world-renowned national and tribal parks and monuments (e.g., Grand Canyon, Zion, Bryce, Arches, Canyonlands, Monument Valley, and...

The Blind Zone of Earthquake Early Warning

Residents in California, Oregon, and Washington have been told that earthquake early warning (EEW) is at their doorstep and will alert them to the shaking from an earthquake before it arrives. Some media reports have said there will be “up to a minute of warning”. The problem is, for onshore earthquakes these claims are exaggerated, and under some conditions a warning is not scientifically or...

Remote Sensing and Dryland Management

Drylands (areas characterized by low precipitation, high evapotranspiration, and low soil moisture) occupy around 40-45% of the earth’s surface. Many drylands contain high biodiversity and provide essential ecosystem services (e.g., livestock forage, agricultural production, pollination) for nearly 1/3 of the world’s population who live in drylands.  Given limited precipitation and other...

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.
