Aerial Photo of the mouth of the Elwha River and its estuaries, showing a visible sediment plume blossoming out into the sea.USGS scientist quoted in “Why the World's Rivers are Losing Sediment and Why It Matters”

USGS research geologist Jon Warrick was quoted in an article about the importance of river-borne sediment for helping coastal-wetland growth keep pace with sea-level rise. Titled “Why the World’s Rivers Are Losing Sediment and Why It Matters,” the article was published June 20 in Yale Environment 360, an online magazine covering global environmental issues. Warrick leads a USGS project studying how the removal of two large dams from the Elwha River in Washington State is changing the region’s coastal areas. He described the expansion of coastal landforms by sediment released during and after dam removal, and he noted that the best way to free sediment trapped behind a dam depends on the dam’s purpose and the unique nature of the river.

Photograph shows the tsunami wave, generated by JapanUSGS scientist interviewed for KQED podcast “What Would Really Happen if a Tsunami Hit the Bay Area?”

USGS research geophysicist Eric Geist spoke to Olivia Allen-Price of KQED Radio (San Francisco) for a podcast addressing the question: “If a tsunami were to hit the Golden Gate, what would be its real effect on communities facing the San Francisco Bay?” Geist described the impacts of tsunamis generated by large, distant earthquakes as they hit California’s Pacific coast and enter San Francisco Bay, where strong currents could damage piers and vessels. Steven Ward, professor at University of California, Santa Cruz, shared a computer simulation showing how a tsunami wave would fan out after coming through the Golden Gate, flooding low-lying areas in San Francisco and dissipating as it moved farther into the bay. Listen to the podcast, part of the Bay Curious series. View a larger version of the photo shown here: Tsunami generated by Japan's 2011 Tohoku earthquake makes its way through San Francisco Bay.

Map shows subduction zones around the Pacific Rim.Just published: “Reducing Risk Where Tectonic Plates Collide—A USGS Plan to Advance Subduction Zone Science”

Most of the world’s earthquakes, tsunamis, landslides, and volcanic eruptions are caused by the continuous motions of tectonic plates that make up the Earth’s outer shell. The most powerful of these natural hazards occur in subduction zones, where two plates collide and one is thrust over another. The U.S. Geological Survey’s “Reducing Risk Where Tectonic Plates Collide—A USGS Plan to Advance Subduction Zone Science” is a blueprint for building the crucial scientific foundation needed to inform the policies and practices that can make our Nation more resilient to subduction zone-related hazards. Read a USGS Fact Sheet summarizing the plan, or read the full report. Contact: Joan Gomberg, gomberg@usgs.gov, 206-616-5581posted: 2017-06-22

USGS Research Scientist quoted in Inside Climate News regarding prognosis of reef recovery following coral bleaching

USGS Research Marine Biologist Ilsa Kuffner (SPCMSC) was quoted in a June 21, 2017 article of Inside Climate News. The author of the article asked Kuffner to comment on a NOAA press release out this week regarding the winding down of the 3rd global coral bleaching event and the prognosis for recovery of coral reef ecosystems. Kuffner explained that, while temperatures have abated and some coral populations have survived the bleaching, many corals are now succumbing to disease outbreaks, including in the Florida Keys. Several coral species are trending quickly toward local extinction, forcing decisions and immediate management actions to preserve the remaining genetic diversity.

Graphic showing change in topography at the Big Sur landslide, from May 27 to June 13.New Land Created by Slide on Big Sur Coast is Eroding

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. The large slide buried State Highway 1 beneath more than 65 feet of rock and dirt, and created about 13 acres of new land bulging into the ocean. Between May 27 and June 13, the seaward edge of the landslide retreated about 16 feet. USGS scientists collect air photos of the slide area weekly to biweekly as weather permits. They use “structure-from-motion” software to turn the photos into 3D maps from which they measure changes in ground elevation.

USGS USGS maps, measures huge landslide on California's Big Sur coast

USGS scientists analyzing before-and-after air photos have calculated the size of the May 20 landslide on California’s Big Sur coast, about 140 miles south of San Francisco. They are sharing their information with California Department of Transportation (Caltrans) engineers assessing the slide. Preliminary calculations indicate that the landslide moved approximately 2 million cubic meters of material, enough to fill 800 Olympic-sized swimming pools. It buried State Highway 1 more than 20 meters (65 feet) deep and added more than 50,000 square meters (about 13 acres) of new land to the coast. USGS scientists shot air photos of the Big Sur coast in March and May 2017. Using “structure-from-motion” software, they transformed these and earlier photos into 3D maps that allow them to precisely measure areas and changes in ground elevation. They plan to keep monitoring the slide area via weekly airplane flights and, starting in June, drone flights.

Watch an animation of USGS computer-generated "before" and "after" images at Big Sur landslide. Red areas are lower, blue/purple higher.
