MacroseismicIntensity, Subduction tectonic Models, Ecuadorian CoastalAbstract
A seismic risk assessment study relative to the Ecuadorian coasts is presented in this report. The likely maximum magnitude and the maximum offset for each active and capable fault are calculated using empiric regression law between magnitude and offset/rupture(Well & Coppersmith,1994). Seismic spatial distribution and subduction tectonic models allowed identifyingseismogenic structures in the crustal and mega thrust earthquake areas. Based on 129 historical earthquakes, 985 maximum felt intensity data (MSK-1956 and ESI-2007 scales) and 5997 instrumental seismicity data among Mw 4,0 and 8,8, they seismicity level for the Ecuadorians coasts has been evaluated. Secondary geological effects that could be generated during an crustal earthquake in the Guayaquil city area were also hypotized in this study
