According to Mexico's National Seismological Service (SSN), the quake hit on Tuesday 12 January 2021 at 2:52 pm local time at a very shallow depth of 4 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
