USGS scientists collect sediment samples in a gas hydrates area during a cruise on the U.S. Atlantic margin in 2015.

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Oregon Inlet, North Carolina. View looking west along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beach and inundated the low area in the backshore at Oregon Inlet (A, green box, blue arrows).

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Hatteras, North Carolina. View looking north along the North Carolina shore. Waves and surge from Hurricane Joaquin eroded the beach, causing significant shoreline retreat and a narrower beach at the location of the Hurricane Isabel breach in 2003 (green arrow).

CalVO's Stuart Wilkinson skis out to a remote seismic instrument in the Long Valley volcanic region to perform routine maintenance.

Eruptions between 1064 and 1067 AD produced three lava flows that covered 8 km² (3 mi²) and a field of scoria and spatter that covers 2300 km² (890 mi²). Archeological evidence shows that there were communities of people living in the area who were impacted by the eruption.

USGS scientists Kate Allstadt and Cynthia Gardner tell the story of the May 18, 1980 eruption of Mount St. Helens and how the catastrophic landslide, lateral blast, and lahar changed the landscape.

Study region along the Queen Charlotte-Fairweather fault offshore southeastern Alaska. Rectangles show locations of the two USGS-led marine geophysical surveys in May and August 2015. The third cruise was offshore Haida Gwaii, British Columbia, and southern Alaska in September 2015.

Enlarged from previous figure, this map shows a string of basins along the fault and offset of the south wall of the Yakobi Sea Valley. Line A–B marks the location of multichannel seismic-reflection profile.

Multichannel seismic-reflection profile showing sediment layers beneath the seafloor disrupted by the Queen Charlotte-Fairweather fault near Cross Sound. The profile is approximately 16 kilometers across, and it extends approximately 370 meters beneath the seafloor. See related multimedia below, for the location of this profile.
