QuakeScan is a global earthquake database and exploration platform that organizes records from the USGS Earthquake Hazards Program into a searchable resource. It helps users explore seismic activity worldwide, from recent tremors to historical events, with filters for location, date, magnitude, and depth. Visitors can browse current and significant earthquakes, review event details such as coordinates and time, and investigate earthquake histories for particular regions or fault zones.

The site also offers a recent-earthquakes map, records organized by year, magnitude-based categories, and statistics on earthquake activity and active countries. Its listings include both minor events and major earthquakes, with information such as location, magnitude, and depth where available. QuakeScan publishes educational articles about earthquake maps, public seismic data, and offshore earthquakes, and provides a section for tsunami alerts.

The platform states that its data comes from the USGS but that QuakeScan is not affiliated with the agency. By bringing searchable records, browsing tools, statistics, and explanatory content together, QuakeScan makes public earthquake data easier to explore and understand
