Where can I get official earthquake information for Chile?
For official information, warnings and safety advice, follow Centro Sismológico Nacional (https://www.sismologia.cl/) and your local 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.
