A magnitude 4.2 earthquake near Loreto, Baja California Sur, Mexico, was reported only 24 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 10 km beneath the epicenter after midnight on Wednesday 20 January 2021 at 12:48 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.2 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Loreto (pop. 14,700) located 85 km from the epicenter.
