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.

If you felt this quake (or if you were near the epicenter), please share your experience and submit a short "I felt it" report! Other users would love to hear about it!
If you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
