An earthquake of magnitude 5.0 occurred in the morning on Thursday 25 February 2021 at 9:37 am local time near Dededo Village, Dededo, Guam, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at an intermediate depth of 136 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 United States Geological Survey, which listed it as a magnitude 5.1 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.1.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Dededo Village (pop. 44,900) located 33 km from the epicenter, Tamuning-Tumon-Harmon Village (pop. 19,700) 37 km away, Hagåtña (pop. 1,100) 39 km away, and Talofofo Village (pop. 3,200) 52 km away.
