Magnitude 4.9 earthquake strikes near Managua, Departamento de Managua, Nicaragua

4.9 quake 23 May 4:37 pm (GMT -6)
4.9 quake 23 May 4:37 pm (GMT -6)
A magnitude 4.9 earthquake near Managua, Departamento de Managua, Nicaragua, was reported only 13 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a moderately shallow depth of 58 km beneath the epicenter in the afternoon on Sunday 23 May 2021 at 4:37 pm 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.2.
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 Masachapa (pop. 5,000) located 30 km from the epicenter, San Rafael del Sur (pop. 29,800) 40 km away, Diriamba (pop. 35,000) 58 km away, San Marcos (pop. 23,300) 65 km away, Ciudad Sandino (pop. 50,000) 74 km away, Managua (pop. 973,100) 78 km away, and Granada (pop. 89,400) 89 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tipitapa (pop. 50,000) located 94 km from the epicenter, Leon (pop. 144,500) 96 km away, and Nicaragua (pop. 30,000) 97 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
