ANÁLISIS DE FOTOLINEAMIENTOS DE LA REPUBLICA DOMINICANA

Abstract

With the aim of implementing an instrumental network for monitoring the micro-seismicity ofthe whole territory of the Dominican Republic, a remote sensing study was performed.This study was based on georeferenced black/white images LANDSAT TM (Thematic Mapper) at a scale1:250.000. The aim of the study was the recognition and analysis of lineaments of the entire territory of Dominican Republic. The term “lineament” corresponds to all linear elements, generally rectilinear or slightly curvi-linear, that intersect topographic surface and are connected with geological phenomena that concern bedrock.All lineaments recognized (17.300 for a total lenght of 26.000 km) were plotted on a map at a 1:500.000 scale.Furthermore, a statistic analysis of the lineament radial distribution and of their persistence was done. Lineaments recognized can be compared with bibliographic data and are compatible with cinematic models presentlyapplied to explain the recent history of Dominican Republic.
