Strong magnitude 5.0 earthquake at unknown depth2 May 05:09 UTC: First to report: VolcanoDiscovery after 4 minutes.2 May 05:09: Now using data updates from GFZ2 May 05:23: Now using data updates from EMSC2 May 05:23: Now using data updates from USGSUpdate Sat, 2 May 2026, 05:18Moderate 4.7 quake hits near La Rioja, Departamento de Capital, La Rioja Province, ArgentinaAn earthquake of magnitude 4.7 occurred early morning on Saturday, May 2nd, 2026, at 2:05 am local time near La Rioja, Departamento de Capital, La Rioja Province, Argentina, as reported by the German Research Centre for Geosciences (GFZ).According to preliminary data, the quake was located at an intermediate depth of 79.20 km. 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 citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.7 earthquake as well.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Chamical (pop. 13,400) located 39 km from the epicenter, Villa San Agustin (pop. 6,900) 86 km away, and La Rioja (pop. 178,900) 94 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)I: Not felt1613–613 km (381–381 mi)613 km (381 mi)II: Very weak shaking3133–248 km (83–154 mi)172 km (107 mi)III: Weak shaking420–100 km (12.6–62 mi)60 km (37 mi)IV: Light shaking371–76 km (44–47 mi)74 km (46 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (13 in total) could be used for geographic statistics.Get the Android appI didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 10 km2 (4 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 5 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)May 2, 2026 02:04 am (GMT -3)28 minutes ago - felt5.010 km0 km - This quake74 km SE of La Rioja, Departamento de Capital, La Rioja Province, ArgentinaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquakeStrongest in 8 yearsThe earthquake was the strongest to hit this part of Argentina in over 8 years.
