Update Wed, 31 Mar 2021, 09:03
Moderate tremor of magnitude 4.2 just reported 34 km southeast of Mexicali, Mexico
4.2 quake 31 Mar 1:56 am (GMT -7)
4.2 quake 31 Mar 1:56 am (GMT -7)
A magnitude 4.2 earthquake near Mexicali, Mexicali Municipality, Baja California, Mexico, was reported only 7 minutes ago by the United States Geological Survey, considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 19.4 km beneath the epicenter early morning on Wednesday 31 March 2021 at 1:56 am local time. 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 4.2 earthquake as well.
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.
Weak shaking might have been felt in Delta (pop. 5,200) located 6 km from the epicenter, Nuevo Leon (pop. 3,700) 6 km away, Guadalupe Victoria (pop. 17,100) 17 km away, Doctor Alberto Oviedo Mota (pop. 8,100) 19 km away, Puebla (pop. 15,200) 23 km away, and Mexicali (pop. 689,800) 34 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Calexico (pop. 40,100) located 41 km from the epicenter, Santa Isabel (pop. 29,300) 42 km away, San Luis (pop. 31,500) 45 km away, and San Luis Rio Colorado (pop. 158,100) 45 km away.
