Magnitude 4.2 earthquake strikes near Guayaquil, Ecuador

4.2 quake Ecuador - Guayas, A 10.90km De Bucay, 15 Nov 5.52 pm (GMT -5)

An earthquake of magnitude 4.2 occurred in the afternoon on Sunday 15 November 2020 at 5.52 pm local time near the town of La Troncal, 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 very shallow depth of 5 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.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc. Weak shaking might have been felt in La Troncal (pop. 36,400) located 19 km from the epicenter, Coronel Marcelino Maridueña (pop. 7,300) 24 km away, Naranjito (pop. 34,200) 30 km away, Alausí (pop. 14,300) 44 km away, Milagro (pop. 133,500) 44 km away, Eloy Alfaro (pop. 167,800) 71 km away, Cuenca (pop. 277,000) 72 km away, and Guayaquil (pop. 1,952,000) 74 km away.
