Guatemala Earthquake 1976. A Mayan stele at Quirigua in the Motagua Valley that cracked near the base as a result of rocking during the February 4, 1976, earthquake. The wooden braces were installed to protect the stele from further damage by seismic shaking during the aftershock sequence. 1976. Slide 50, U.S. Geological Survey Open-File Report 77-165.

Guatemala Earthquake 1976. Pacaya volcano 25 kilometers south of Guatemala City during an ash eruption shortly after the February 4, 1976, earthquake. Although the amount of ash erupted from the volcano may have increased slightly as a result of the earthquake, the apparent increase is well within the limits of the variation in the volcano's activity that had been observed for roughly a year prior to the earthquake. 1976.

Guatemala Earthquake 1976. Map showing the Motagua faulted in relation to the boundaries of the Cocos and Caribbean plates. Large arrows indicate the relative plate movement directions, and numbers in parentheses indicate the inferred annual rate of movement in centimeters. The Motagua fault is part of the transform fault system that comprises the northern boundary of the Caribbean plate. Plate boundaries and motions from Jordan, T.H., 1976: Journal of Geophysical Research, v.80, p.4433-4439. Susan Hunt drafted this figure. 1976.

Guatemala Earthquake 1976. A suggested model showing combined relative movement between the North American (green), Cocos (blue), and Caribbean (yellow and orange) plates and within the Caribbean plate to account for the complex tectonics of northern Middle America. Predominantly extensional faulting (blue zones) has caused fragmentation of the western part of the Caribbean plate. As a consequence, the northern part of the plate (yellow) may be decoupling from the southern part (orange) along the major northwest- southeast trending system of graben that follows the volcanoes (black dots) of the Middle America arc. White arrows show directions and relative amounts of long term movements of the plates and plate fragments; black arrows, relative movements along the Motagua fault system. Susan Hunt drafted this figure. 1976. Slide 53, U.S. Geological Survey Open-File Report 77-165.

Guatemala Earthquake 1976. Block diagram showing the relation of the Motagua fault zone and the inferred zone of decoupling within the Caribbean plate to major tectonic and volcanic elements in Guatemala and contiguous countries. Guatemala is subject to earthquakes that are generated by movement on 1.) the transform fault system between the North American and Caribbean plates (which includes the toe of the Motagua fault), 2) the mega thrust zone between the Cocos and Caribbean plates, 3) extensional faults within the Caribbean plate, and by 4) earthquakes associated with volcanism along the Middle America volcanic chain. Susan Hunt drafted this figure. Slide 54, U.S. Geological Survey Open-File Report 77-165.
