The 1931 Nicaragua earthquake devastated Nicaragua's capital city Managua on 31 March. It had a moment magnitude of 6.1 and a maximum MSK intensity of VI (Strong). Between 1,000 and 2,450 people were killed. A major fire started and destroyed thousands of structures, burning into the next day.

Nicaragua Country in Central America

Nicaragua, officially the Republic of Nicaragua, is the largest country in the Central American isthmus, bordered by Honduras to the northwest, the Caribbean to the east, Costa Rica to the south, and the Pacific Ocean to the southwest. Managua is the country's capital and largest city and is also the third-largest city in Central America, behind Tegucigalpa and Guatemala City. The multi-ethnic population of six million includes people of indigenous, European, African, and Asian heritage. The main language is Spanish. Indigenous tribes on the Mosquito Coast speak their own languages and English.

Managua Place in Nicaragua

Managua is the capital and largest city of Nicaragua, and the center of an eponymous department. Located on the southwestern shore of Lake Managua, it had an estimated population 1,042,641 in 2016 within the city's administrative limits and a population of 1,401,687 in the metropolitan area, which additionally includes the municipalities of Ciudad Sandino, El Crucero, Nindirí, Ticuantepe and Tipitapa.

The Medvedev–Sponheuer–Karnik scale, also known as the MSK or MSK-64, is a macroseismic intensity scale used to evaluate the severity of ground shaking on the basis of observed effects in an area of the earthquake occurrence.

International Seismological Centre organization

The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depositary of global earthquake parameter data."
