Data Sources

QuakeScout aggregates data from authoritative scientific institutions. All earthquake data is sourced from publicly available government and academic datasets.

USGS Earthquake Hazards Program ↗

Primary source for all real-time and recent earthquake data. The USGS monitors seismic activity globally through a network of 2,000+ stations. Data includes magnitude, depth, location, tsunami warnings, and felt reports.

Data Used

Real-time earthquakes, historical events, magnitude data, depth measurements, felt reports, tsunami alerts

Update Frequency

Real-time (every 60 seconds)

USGS FDSNWS Event API ↗

The Federation of Digital Seismograph Networks (FDSN) web service API provides programmatic access to the USGS earthquake catalog.

Data Used

Earthquake search by location, time, magnitude; event details; nearby earthquakes

Update Frequency

Real-time

Global Earthquake Model (GEM) Foundation ↗

International collaborative effort to develop tools and resources for earthquake risk assessment. Provides country-level hazard and risk data.

Data Used

Country risk levels, tectonic plate boundaries, fault line data

Update Frequency

Annually

NOAA National Centers for Environmental Information ↗

NOAA maintains historical records of significant earthquakes dating back to 2150 BC, including damage reports, fatalities, and tsunami generation data.

Data Used

Historical earthquake records, fatality counts, damage assessments

Update Frequency

Periodically

OpenStreetMap / CARTO ↗

Map tiles and geographic data used for interactive earthquake maps throughout the site.

Data Used

Map tiles (Voyager style), geographic boundaries

Update Frequency

Continuous

Data Accuracy Disclaimer

While we strive to present data as accurately as possible, earthquake measurements (particularly magnitude and depth) may be revised by the USGS after initial reporting. QuakeScout reflects the most recent data available from our sources. This site should not be used as an emergency alert system — always follow official guidance from local authorities during seismic events.
