Moderate 4.4 quake hits near Llallagua, Rafael Bustillo, Departamento de Potosi, Bolivia

4.4 quake 18 Jul 5:59 pm (GMT -4)
4.4 quake 18 Jul 5:59 pm (GMT -4)
A magnitude 4.4 earthquake near Llallagua, Rafael Bustillo, Departamento de Potosi, Bolivia, was reported only 9 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 an intermediate to considerable depth of 258 km beneath the epicenter in the afternoon on Sunday 18 July 2021 at 5:59 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.4 earthquake 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 Challapata (pop. 8,000, 11 km away), Llallagua (pop. 28,100, 65 km away), and Huanuni (pop. 15,500, 74 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.
