What inspired a USGS geologist to study how dam removal changes rivers. Profile of Amy East.
USGS research geologist Kate Scharer with her finger on the Fairweather Fault in southeast Alaska. The magnitude 7.8 Lituya Bay earthquake caused shaking that toppled trees along the fault, which left a break in the forest shown here.
Nearly 60 years after a magnitude 7.7 earthquake struck Lituya Bay, Alaska — leading to a tsunami that devastated the area — six U.S. Geological Survey geologists revisited the isolated region of Alaska, to pick up where their scientific predecessors left off. In this photo, members of the USGS research team pause to take in the view of South Crillon Glacier from a study site along the...
Trench site along the southern Fairweather Fault, in Glacier Bay National Park, Alaska. The alluvial fan at left consists of lake, stream channel and debris flow deposits impounded by the Fairweather Fault scarp, at right.
Screenshot of Total Water Level and Coastal Change Forecast Viewer on June 4, 2016, two days before Tropical Storm Colin was expected to hit Florida’s Gulf of Mexico coast. This forecast is for Treasure Island (blue balloon on map) on the day of Colin’s arrival (June 6, 2016). Top right: Expected mean (...
On the remote western coast of Australia lies a UNESCO World Heritage Site above and below the sea. Researchers from the U.S. Geological Survey and University of Western Australia convened here at Ningaloo Reef and Jurabi Coastal Reserve to embark on the most extensive study EVER done into how coral reefs shape our coasts.
Heavy rains that began falling during Memorial Day weekend in late May 2016 pushed the Brazos River, 30 miles southwest of Houston, Texas, toward a near-record flooding stage that hasn’t been seen since 1913, according to the National Weather Service (NWS).
SANTA CRUZ, Calif. — Coral reefs, under pressure from climate change and direct human activity, may have a reduced ability to protect tropical islands against wave attack, erosion and salinization of drinking water resources, which help to sustain life on those islands.
CORAM, N.Y. -- A new study that looked in part at how damage estimates evolve following a storm puts the total amount of building damage caused by Hurricane Sandy for all evaluated counties in New York at $23 billion. Estimates of damage by county ranged from $380 million to $5.9 billion.
ANCHORAGE, Alaska — In a new study published today, scientists from the U.S. Geological Survey found that the remote northern Alaska coast has some of the highest shoreline erosion rates in the world. Analyzing over half a century of shoreline change data, scientists found the pattern is extremely variable with most of the coast retreating at rates of more than 1 meter a year.
Significant strides in science have been made to better understand potential ground shaking from induced earthquakes, which are earthquakes triggered by man-made practices.
MENLO PARK, Calif.— Smartphones and other personal electronic devices could, in regions where they are in widespread use, function as early warning systems for large earthquakes according to newly reported research.
MENLO PARK, California — Los teléfonos móviles y otros dispositivos electrónicos personales podrían ayudar en las regiones donde se encuentran en uso generalizado, y pueden funcionar como sistemas de alerta para terremotos mayor según la nueva investigación científica recien publicada.
The U.S. Geological Survey expects to award up to $7 million in grants for earthquake hazards research in 2016.
A new California earthquake forecast by the U.S. Geological Survey and partners revises scientific estimates for the chances of having large earthquakes over the next several decades.
Reactivated faults that have produced thousands of Oklahoma earthquakes are capable of causing larger seismic events, according to U.S. Geological Survey research published today in Geophysical Research Letters.
MENLO PARK, Calif.— A paper published today in Science provides a case for increasing transparency and data collection to enable strategies for mitigating the effects of human-induced earthquakes caused by wastewater injection associated with oil and gas production in the United States.
A new study to examine how people who live downwind of Kīlauea Volcano cope with volcanic gas emissions, or vog, is currently underway.
RESTON, Va.-- Aftershocks from the 2011 Virginia earthquake have helped scientists identify the previously unknown fault zone on which the earthquake occurred.
