Past earthquakes here. A magnitude 6.2 earthquake 287 km ne of this event struck Managua, Nicaragua on December 23, 1972 (UTC), with estimated population exposures of 264,000 at intensity VII and 311,000 at intensity VIII, resulting in a reported 11,000 fatalities.

Local buildings. Overall, the population in this region resides in structures that are highly vulnerable to earthquake shaking, though some resistant structures exist. The predominant vulnerable building types are mud wall and adobe block construction.

Population and intensity modelled by USGS PAGER. Estimates, not a count of people affected.
