Moderate magnitude 4.9 earthquake strikes in the evening 15 km southeast of Pijijiapan, Mexico
4.9 earthquake 23 September 20:59 (GMT -5)
According to preliminary data, the earthquake was located at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deep ones because they are closer to the surface. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes, as seismologists review the data and refine their calculations, or when other agencies release their report.
Our monitoring service identified a second report from the Euro-Mediterranean Seismological Center (EMSC) which also listed the 4.9 magnitude earthquake.
Based on preliminary seismic data, the quake should have been widely felt by almost everyone in the epicenter area. It could have caused slight to moderate damage.
Moderate tremors probably occurred in Ceniceros (350 inhabitants) located 1 km from the epicenter.
In El Carmen (1,400 inhabitants) located 6 km from the epicenter, Joaquin Miguel Gutiérrez (Margaritas) (1,600 inhabitants) 9 km away, Pijijiapan (16,900 inhabitants) 15 km and Mapastepec (17,900 inhabitants) .) at 33 km, the earthquake should have been felt as a slight tremor.
Weak tremors could be felt in Villaflores (37,200 inhabitants) located 77 km from the epicenter, Tonala (35,300 inhabitants) 86 km and Huixtla (32,000 inhabitants) 89 km.
