Large-scale poster describing USGS work.

The USGS, in cooperation with the UK Institute of Oceanographic Sciences (IOS) and others, took images of the seafloor 200 miles around the Hawaiian Islands using GLORIA. GLORIA is a long-range sonar that gives a bird’s-eye view of the seafloor.

Sea Beam bathymetric map of southern Escanaba Trough study area. Contour interval is 10m and is noted by color change. Locations of single- channel water-gun reflection profiles 4 to 12, cruise L1-86-NC, are shown.

Photo shows the side of an actively venting massive sulfide chimney colonized by tube worms and palm worms.

Sea Beam bathymetric map of Escanaba Trough from 1985. A, Northern half. B, Southern half. Contour interval is 50 m; each color change represents 100 m. Yellow indicates areas of no data.

Photo shows tube worms and anemones colonizing massive sulfide talus where diffuse hydrothermal venting is occurring.

Photo shows side of sulfide mound showing cluster of tube worms, anemones, and bacterial mats.

Hydrothermal deposits (primarily barite) adjacent to site of active venting. Shiny black material is possibly pyrobitumen.

Older, oxidized sulfide deposit colonized by sponges at SESCA site, southern half of Escanaba Trough.

Sulfide mound and talus at NESCA site, northern half of Escanaba Trough. Rectangular marker at center of photograph is 15 by 30 cm.

Dynaphot photomicrographs of foraminifers from Escanaba Trough. A-D, Rhabdammina sp.

Glassy, fresh pillow basalt flow at the NESCA site, northern half of Escanaba Trough.

George Tate playfully brandishes a grappling hook in a boat in Cook Inlet, Alaska, 1978. The driver (not shown) and George are about to motor away from the research vessel Sea Sounder to drag for the large tripod dubbed the Geoprobe. The apparatus had not deployed its recovery float and line, so the scientists had to try to hook it up off the seafloor.

Photograph taken in 1964 of the main part of the Chenega village site in Alaska. Pilings in the ground mark the former locations of homes swept away by tsunami waves. The schoolhouse on high ground was undamaged.

Aftermath of the 1960 Chilean tsunami in Hilo, Hawaii, where the tsunami caused 61 deaths.

In 1932, the U.S. Coast Guard commissioned the construction of a 165-foot, 1,500-horsepower ship in Bay City, Michigan. This was the U.S. Coast Guard Cutter (USCGC) Escanaba.

The Escanaba was built by Western Pipe and Steel Company in San Pedro, California, and began sailing in 1946. This 255-foot gunboat operated from its homeport in Alameda, California, until it was decommissioned in 1954. 

View of John Muir School on Pacific Avenue in Long Beach, California, showing damage from the March 10, 1933 Long Beach earthquake. Photo taken 8 days after the earthquake, on March 18, 1933. Photo by W.L. Huber, USGS.

One of the most well-known photographs by George R. Lawrence, taken May 28, 1906, about 6 weeks after the Great San Francisco earthquake which occurred on April 18. The 160-degree panorama was taken from a camera suspended from a kite 2,000 feet in the air. The view looks up Market Street with the waterfront and Union Ferry Building in the foreground.
