About Richter Center
A clear, free view of every earthquake on Earth: what is shaking now, near you and through a century of history.
Richter Center maps every earthquake of magnitude 2.5 or more minutes after seismographs record it, and keeps the history: every magnitude 4.5+ earthquake worldwide since 1900 and every 2.5+ since 2000, more than 830,000 in all.

Where the data comes from
Earthquakes come from the U.S. Geological Survey's earthquake catalog (ComCat), which combines networks around the world; places come from GeoNames. See data and methods for the details.
Not a warning service
Richter Center is for information and curiosity. It is not an early-warning or emergency service: in an emergency, follow your local authorities and official alerts.
