About this data

Earthquake data comes from the USGS real-time feeds and is checked every 5 minutes. Early magnitudes, locations and depths are automatic and can change when seismologists review the event. Nearest towns are calculated from GeoNames places with 15,000 or more people; an earthquake is listed under a country or state when the nearest such town within 300 km (186 mi) is there, or when USGS names that place.
