The coastline of Guatemala lies above the convergent boundary where the Cocos Plate is being subducted beneath the North American Plate or Caribbean Plate along the line of the Middle America Trench. The northern part of the country hosts the Motagua Fault and Chixoy-Polochic Fault, The Motagua Fault was the source of many destructive earthquakes in Northern Guatemala, most notably the 1976 Guatemala earthquake with a magnitude of 7.5.[4][5]
