Epicenters from the SSN catalog are plotted for September to October 2017, highlighting seismicity immediately following the Tehuantepec earthquake. The different colors represent different depths of the earthquakes. Aftershocks were generally shallow closer to the main shock location and deeper inland, following the subduction interface. However, north of the Tehuantepec ridge a region of shallow inland aftershocks shows that there is additional complexity in the faults beneath the surface.
