McIntosh, and T. Pratt (USGS, Seattle). Downtown Managua in the background was completely destroyed by an earthquake in 1972 that was produced by a fault that extends from from Lake Managua through the city. This hotel was one of the few highrise buildings in the downtown area that was left standing. A former resident of the hotel was billionaire Howard Hughes who hastily departed to the US by private jet following the earthquake.
