Geological framework of earthquakes occurrence in Nicaragua, Central America

Abstract

An assessment of earthquakes occurrence in Nicaragua was conducted by reviewing regional and local active tectonic structures, historic and some instrumentally recorded earthquakes as well as other pertinent available geologic data. Most of the seismic energy released results from earthquakes generated along the steeply dipping Benioff-Wadati Subduction Zone. Other main sources are the active tectonic structures and the volcanic front. In the viewpoint of seismic hazard, earthquakes from active tectonic structures, although small to moderate size are more dangerous as they tend to occur in densely populated areas. -from Authors
