4.6 quake ANTOFAGASTA, CHILE, Apr 21, 2022 3:27 pm (GMT -4)
A magnitude 4.6 earthquake near San Cristobal de Lipez, Departamento de Potosi, Bolivia, was reported only 12 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate depth of 80 km beneath the epicenter early afternoon on Thursday, April 21st, 2022, at 3:27 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 German Research Centre for Geosciences (GFZ), which listed it as a magnitude 4.7 earthquake. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.7.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include San Cristobal de Lipez (pop. 75) located 99 km from the epicenter.
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.
