The September 7 Chiapas, Mexico (M=8.1) and the September 19 Puebla, Mexico (M=7.1) earthquakes caused significant damage and loss of life. These were not the typical subduction plate boundary compressional events along the subduction interface of the Middle American Trench. Furthermore, the earthquakes were located about 640-km from each other, a far enough distance to suggest no link between them. We will investigate several questions remaining about these earthquakes by deploying seismic sensors around these two earthquakes and in between them and analyzing the data collected in coordination with our colleagues in Mexico.
