Event narrative

Managua, the capital city of Nicaragua, was struck by an earthquake of magnitude 6.2 (Mw) at 00:29 local time on the early morning of December 23rd 1972. Severe damage was experienced due to the combination of a shallow focal depth (6.2 km) and the extensive faulting through the city. Within an hour after the main shock, two aftershocks that exceeded magnitude 5 occurred. The earthquake caused widespread damage, among Managua's residents, 5,000 were killed, 20,000 were injured and over 250,000 were left homeless. 27 km² of the city (residential areas) were severely damaged and 13 km² of the downtown area were nearly totally destroyed, making this the most affected area due to the earthquake. Most of the buildings sustained significant structural damage from the seismic ground movement. Older houses constructed in taquezal (architectural construction made of a timber frame with stone filling, finished with plaster, and topped by unmortared clay tiles) were completely damaged. At the same time an estimated 53,000 homes in the city were affected and approximately 2000 people injured
