Title: Underwater Secrets of the Hayward Fault Zone: Integrated 3D imaging to understand earthquake hazards Underwater imaging provides a unique opportunity to study urban fault hazards. How do we link surface structures to depths where earthquakes occur? How does "acoustic trenching" help us understand earthquake history?

Image of the Week: Okefenokee National Wildlife Refuge Fire Landsat 8's Operational Land Imager captures the scene as many acres burn in the Okefenokee National Wildlife Refuge. Series Description: "Image of the Week" is a series of videos produced by the USGS Earth Resources Observation and Science (EROS) Center featuring remotely sensed imagery of the Earth's landscapes. Each week a new...
Superimposed on beach photo: dense grid of blue dots across sandy beach and over ocean. Ditto 3 lines that cross the shore.

Frame from video of Cowells Beach in Santa Cruz, California, showing “pixel instruments” measured continuously during the video and used to estimate different coastal processes. The blue dots represent an array of pixels used by a computer program called cBathy to estimate seafloor depths (bathymetry). The red, orange, and yellow lines are cross-shore arrays of pixels used for measuring wave...

USGS ocean engineer Gerry Hatcher (left) and USGS postdoctoral oceanographer Shawn Harrison make adjustments to a computer controlling two video cameras on the roof of the Dream Inn, a 10-story hotel overlooking Monterey Bay in Santa Cruz, California. One camera looks eastward over Santa Cruz Main Beach and boardwalk, and the other southward over Cowells Beach. Since May 2017, the cameras have...

Snapshot, or first frame of from a 10-minute video shot on May 6, 2017, in Santa Cruz, California. Researchers at the USGS are using these and other video images to improve understanding and computer modeling of beach processes, especially those that change the coast. Half-hourly images are posted online during daylight hours. See also, the time-averaged image from this beach video .

“Variance” image produced from video shot at Cowells Beach in Santa Cruz, California, on May 6, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright areas along and beyond the shore where waves were breaking. Researchers are using these and other...

Time-averaged image, or “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during a 10-minute video taken at Santa Cruz, California, on May 6, 2017. Blurred white zones show where waves are breaking. Line between wet and dry sand shows the maximum height on the beach reached by the waves (“runup”). Researchers at the USGS are using these and other video images...
A cabin along Alaska's Arctic coast was recently washed into the ocean because the bluff it was sitting on eroded away.

The USGS Texas Water Science Center has developed a new mobile application called “Water On-the-Go” that gives people easy access to current conditions in streams across Texas. The information reflects what is happening in streams near you at that very moment. Go to -- https://txpub.usgs.gov/water-onthego -- to see where waters are rising and how current conditions are changing around you. #...

Nor'easter
June 19, 2017

Living in the Outer Banks means living with the power of the sea. Jutting out from North Carolina’s coast into the Atlantic Ocean, this series of sandy barrier islands is particularly vulnerable to damage from major storms. In April 2016, another nor’easter was set to strike, but this time, Dare County officials were approached by their local weather forecaster with a new kind of prediction.

4D Photogrammetry of Mud Creek Landslide
June 15, 2017

USGS analysis of air photos collected June 13 shows that new land created by a May 20 landslide on California’s Big Sur coast is eroding. 

Satellite View of the Wilderness Breach
June 9, 2017

When Hurricane Sandy struck the south shore of Long Island, New York, on October 29, 2012, it caused substantial erosion of the beach and dunes. Storm waves cut through Fire Island National Seashore’s wilderness area, forming a breach. The resulting channel allowed water to flow between the Atlantic Ocean and Great South Bay.

June 5, 2017

The U. S. Geological Survey is poised to bring a dynamic array of science and tools to help decision-makers manage and offset effects of increased drought across the United States, according to a drought plan report released today.

The USGS Earthquake Hazards Program recently released a new strategic plan for earthquake monitoring entitled the “Advanced National Seismic System – Current Status, Development Opportunities, Priorities, 2017-2027.”

Prescribed Burn at Tall Timbers Research Station
May 24, 2017

U.S. Geological Survey scientists and partners are taking technology to the next level, using unmanned aircraft systems (UAS), commonly called drones, to acquire both fire intensity and emissions data during prescribed burns.

The frequency and severity of coastal flooding throughout the world will increase rapidly and eventually double in frequency over the coming decades even with only moderate amounts of sea level rise, according to a new study released today in “Scientific Reports.”
