4.4 quake 158 km southwest of La Paz, Bolivia, Sep 7, 2021 9:22 am (GMT -4)
An earthquake of magnitude 4.4 occurred in the morning on Tuesday, September 7th, 2021, at 9:22 am local time near Chuquitira, Provincia de Tarata, Tacna, Peru, as reported by the German Research Centre for Geosciences (GFZ).
According to preliminary data, the quake was located at an intermediate to considerable depth of 165 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.4 as well.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Chuquitira (pop. 4,200, 76 km away), and Desaguadero (pop. 5,300, 94 km away), the quake was probably not felt.
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.
