This book is the outcome of a careful and detailed study of earthquakes in Central America. It combines information from felt effects and instrumental recordings to reassess the location and size of events since the beginning of the instrumental era. Early sections describe the techniques used, with particular emphasis on the determination of earthquake magnitude. The largest section comprises detailed descriptions of more than 700 of the more significant earthquakes, many accompanied by maps of the felt effects. The main catalogue gives details of the location and size of more than 1800 events, with references to associated phenomena such as surface faulting, volcanism and tsunami generation.
