Resumen
El sismo de magnitud 5.3 grados en la escala de Ritcher se convierte en el más importante después de los terremotos de abril y junio de 1983, dado que es el primero que se registra en la recién instalada Red Sismográfica Nacional, operada por el OVSICORI-UNA.
Este documento realiza una interpretación preliminar sobre las características epicentrales e ipocentrales del sismo. Así como el estudio de las intensidades del evento principal.
Se presenta el mapa de intensidades según la escala de Mercalli, combinando la información del mapa con una gira efectuada a la zona de mayores intensidades. En la gira a la zona sur del país se utilizó un cuestionario de intensidades suministrado por los reporteros sísmicos del OVSICORI-UNA, como parte del proyecto de investigación "Sistematización de reportes de intensidad sísmica (UNA-CONICIT)". Durante el trabajo de campo se utilizó una encuesta para determinar la intensidad máxima alcanzada por el sismo en los lugares visitados.

This document makes a preliminary interpretation of the epicentral and ipocentral characteristics of the earthquake. As well as the study of the intensities of the main event. The map of intensities according to the Mercalli scale is presented, combining the information of the map with a tour made to the zone of greater intensities. In the tour to the southern part of the country, a questionnaire of intensities provided by the seismic reporters of OVSICORI-UNA was used, as part of the research project “Systematization of seismic intensity reports (UNA-CONICIT)”. During the field work, a survey was used to determine the maximum intensity reached by the earthquake in the places visited.
