Album caption: Map showing the relation of segments of the Motagua and Mixco faults that moved during the earthquake of February 4, 1976 (in red) to the main shock epicenter, the larger aftershock epicenters, and major structural and volcanic features in northern Central America. Circled numbers along the Motagua fault indicate selected measured sinistral displacements in centimeters. The green lines in the western part of the map area are lineaments, some of which may have undergone minor fault displacement during the earthquake. Guatemala Earthquake 1976. Figures drafted by Susan Hunt. Photo by G. Plafker. Published as slide 1 in the U.S. Geological Survey Open-File Report 77-165. No index card.

Album caption: Wreckage of the J.C. Penney's Department Store at Fifth Avenue and D Street. Building failed after sustained seismic shaking. Most of rubble has been cleared from the streets. Anchorage, Anchorage District, Cook Inlet Region, Alaska, 1964. (Photo by George Plafker). Published as Figure 5 in U.S. Geological Survey. Professional Paper 542-A. 1965.

Album caption: Boulder estimated to weigh 1,700 pounds thrown up 88 feet above the shoreline by a local wave at the place near Shoup Bay. Valdez district, Alaska Gulf region, Alaska. n.d. (Photo by G. Plafker) Published as figure 4 in the U.S. Geological Survey Professional paper 542-G. 1969.

Album caption: Graphs showing measured horizontal displacement (below) and vertical displacement (above) along the 230 km length of the observed surface rupture of the Motagua fault. Displacement across the fault is sinistral (left-lateral) and is almost entirely horizontal with the strike-slip component ranging up to 340 cm and averaging about 110 cm. Vertical displacements are variable and less than 30 percent of the horizontal displacements. Note the large lateral variations in both horizontal and vertical slip. Guatemala Earthquake 1976. Photo by G. Plafker. Susan Hunt drafted the figures for slide 2. Published as slide 2 in the U.S. Geological Survey Open-File Report 77-165. No index card.

Peru Earthquake May 31, 1970. Up the Rio Santa from 4 miles above Caras, showing the area inundated by the flood wave that originated at the Huascaran debris avalanche. The destructive wave overflowed the banks of the Rio Santa almost continuously to the coast, a distance of about 150 kilometers. June- July 1970.

Album caption: Remains of buildings partially damaged by waves along part of Latouche waterfront. Docks, piers, and some buildings in this area were swept away. Approximately 11 feet of tectonic uplift has raised this former port above the reach of most tides. Latouche district, Alaska Gulf region, Alaska. n.d. (Photo by George Plafker). Published as Figure 13 in U.S. Geological Survey. Professional Paper 542-G. 1969.
