Mexico's National Seismological Service (SSN) reported a magnitude 4.6 quake in Mexico near Tonala, Tonalá, Chiapas, only 19 minutes ago. The earthquake hit early morning on Monday 8 February 2021 at 2:56 am local time at a shallow depth of 23 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.6 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Cachimbo (pop. 120) located 75 km from the epicenter, Doctor Belisario Dominguez (La Barra) (pop. 1000) 78 km away, Manuel Avila Camacho (Ponte Duro) (pop. 1,800) 81 km away, Paredon (pop. 6,100) 83 km away, La Linea (pop. 1,500) 85 km away, La Gloria (pop. 1,800) 86 km away, Tonala (pop. 35,300) 92 km away, and Arriaga (pop. 24,400) 100 km away.
