A magnitude 4.2 earthquake near Matias Romero, Matías Romero Avendaño, Oaxaca, Mexico, was reported 35 minutes ago by Mexico's National Seismological Service (SSN), considered the main national agency that monitors seismic activity in Mexico. The earthquake occurred at a shallow depth of 27 km beneath the epicenter early morning on Thursday 29 April 2021 at 3:22 am local time. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
