ISC locations: 1960 to present

What we do

The main purpose of the ISC is to compile the ISC Bulletin; regarded as the definitive record of the Earth's seismicity. Data is collected from over 130 agencies worldwide and is available online soon after being received. The Reviewed ISC Bulletin is typically available 24 months behind real-time and is manually checked by ISC analysts. With sufficient data events in the Reviewed ISC Bulletin are relocated using the ISC location algorithm (ISCloc).
