Early Results from the 2020 M6.4 Indios, Puerto Rico Earthquake Sequence [Poster]
On January 7, 2020 a magnitude 6.4 earthquake occurred 8 km south of Indios, Puerto Rico. This earthquake is part of an ongoing sequence that started on Dec 28, 2019. The sequence includes 11 foreshocks M 4.0 and larger and numerous M 4-5 aftershocks. In the days following the mainshock, seismologists, geologists and engineers mobilized to gather data on the rapidly evolving earthquake sequence. In this session, we hope to bring together experts to discuss early results from the field. We especially encourage presentation of new results that contribute to improved understanding of the hazard posed by the poorly known and potentially tsunamigenic Muertos Trough subduction zone. Potential topics include: 1) high-quality earthquake catalogs, 2) region specific ground motion models, 3) local site amplification, 4) ground failure observations, 5) structural damage observations, 6) fault slip rates and 7) novel and creative methods and parameters that contribute to advancing probabilistic seismic hazard models for Puerto Rico.
