An earthquake of magnitude 5.0 occurred early morning on Thursday 21 January 2021 at 5:15 am local time near Duran, Durán, Provincia del Guayas, Ecuador, as reported by the Institute of Geophysics of the National Polytechnic School in Quito (IGEPN).
According to preliminary data, the quake was located at a moderately shallow depth of 46 km. 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.
