1942 Guatemala Earthquake
The earthquake caused widespread damage in the west-central highlands of Guatemala. Thirty-eight people died in the earthquake. Landslides caused by the combination of the earthquake and the heavy seasonal rains destroyed roads, the Inter-American Highway, and telegraph lines. In Tecpán, in the department of Chimaltenango, more than 60% of the houses were demolished. Damage was reported in some buildings in Antigua Guatemala, including the Palacio de Los Capitanes Generales and some catholic churches. The earthquake could also be felt strongly in Mexico and El Salvador.
This earthquake was a lower crustal intraplate earthquake with a compressional focal mechanism. Tensional activity has been dominant along the down-dip edge along the 1942 rupture zone. It was estimated that earthquakes near the Middle America Trench with magnitudes of about 7.5~8.0 occurred at intervals of 94 ± 54 yrs in southwestern Guatemala. Such historical earthquakes included the earthquakes in 1765, 1902, and 1942.
