1972 Nicaragua earthquake

The 1972 Nicaragua earthquake occurred at 12:29:44 a.m. local time (06:29:44 UTC) on December 23 near Managua, the capital of Nicaragua. It had a moment magnitude of 6.3 and a maximum MSK intensity of IX (Destructive). The epicenter was 28 km (17 mi) northeast of the city centre and a depth of about 10 km (6.2 mi). The earthquake caused widespread casualties among Managua's residents: 4,000–11,000 were killed, 20,000 were injured and over 300,000 were left homeless.[5]

Surface faulting[edit]

One of the most significant geological effects of the 1972 Nicaragua earthquake quake was surface faulting. Examination of the fault lines indicated a lateral motion moving in a northeasterly direction and aftershock data has revealed at least one of the faults extends from the surface to a depth of 8 to 10 kilometers beneath the city of Managua.

Aftershocks[edit]

Within an hour after the main shock, two aftershocks, one of magnitude 5.0 and the other 5.2, occurred at 1:18 a.m. and 1:20 a.m.[7]

Aftermath[edit]

The earthquake changed the face of Managua during its decades of recovery. The city center is no longer clearly defined, as buildings have been constructed away from the city center. During the massive evacuations, the displaced residents set up camp around water resources and areas that remained somewhat unaffected. Although Managua remains Central America's second largest capital and metropolitan area, the bulk of its residents reside in barrios or neighborhoods that are of considerable distance from the city center. Today, in place of the large buildings that used to exist in the center, the government set up the "Plaza de la Fe" (Faith Square) in honor of Pope John Paul II.
