Ecuador, Guayaquil: 2011-2017

Summary

The Guayaquil cluster is named for the city of Guayaquil in southern Ecuador. The cluster takes advantage of a large set of arrival time data from the permanent Ecudoran seismic network operated by the Instituto Geofisico Escuela Politechnica Nacional (IGEPN). The data covers 2016 through 2017 so the cluster is dominated by events from this period. Most events are small but a handful were recorded at teleseismic distances. These are supplemented by seven larger events prior to 2016 that have good depth control. The location calibration analysis was complicated by the fact that nearly all events in the cluster are deeper than 25 km. This leads to trade-offs between event depths and crustal velocity structure that are difficult to resolve. [...]
