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: 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.
