Questions
How many earthquakes happen in Argentina?
In the last 30 days, 14 earthquakes of magnitude 2.5 or greater were recorded in Argentina, 4 of them in the last 7 days. In the last 24 hours, 1 earthquakes of any magnitude were recorded. Most small earthquakes are not felt.
What was the largest recent earthquake in Argentina?

What is the largest earthquake recorded in Argentina since 1900?
According to the USGS catalogue, the largest was a magnitude 7.4 earthquake on 23 Nov 1977 (San Juan, Argentina). Magnitudes of early 20th-century earthquakes are less certain than modern ones.
How deep are earthquakes in Argentina?
14% of the magnitude 2.5+ earthquakes recorded in Argentina in the last 30 days were shallower than 70 km. Shallow earthquakes generally cause stronger shaking at the surface than deep ones of the same magnitude.
Where can I get official earthquake information for Argentina?
For official information, warnings and safety advice, follow your national seismological agency and civil protection authority. This site compiles agency reports and is not a warning service.
Can earthquakes be predicted?
No. Scientists can estimate how likely strong shaking is in a region over years or decades, but no method predicts the time, place and size of a specific earthquake. Aftershocks are expected after large earthquakes and become less frequent over time.
