4.2 quake 59 Km Al Suroeste De La Libertad, El Salvador, 29 Oct 2020 21:40
A magnitude 4.2 earthquake was reported only 10 minutes ago by the Nicaraguan Institute of Territorial Studies (INETER), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a shallow depth of 25 km beneath the epicenter early afternoon on Thursday 29 October 2020 at 3.40 pm local time. The magnitude, exact epicenter location and depth of the quake are likely to be revised within the next few hours as seismologists review data and refine their calculations, or as other agencies issue their report.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Towns or cities near the epicenter where the quake might have been felt, based on preliminary calculations, include La Libertad (pop. 16,900) at a distance of 60 km with weak shaking, Zaragoza (pop. 11,700) at a distance of 72 km with weak shaking, San Salvador (pop. 526,000) at a distance of 87 km with very weak shaking, and Soyapango (pop. 329,700) at a distance of 91 km with very weak shaking.
