Our risk score combines geological and seismic data to give you a realistic snapshot of earthquake danger in
your area.
First, we determine your location and measure the distance to the nearest known fault line, using official
U.S. Geological Survey (USGS) fault maps.
Faults that are classified as active—particularly those with movement in the Holocene epoch (within roughly
the last 11,700 years)—carry higher weight in the score.
Next, we analyze recent earthquake activity from live USGS seismic feeds, looking at events within 500
kilometers of your location over the past week.
Larger and more frequent earthquakes in this radius increase your score.
The final number, scaled from 0 (lowest) to 100 (highest), is a weighted blend of proximity to active faults
and recent seismic activity, providing a balanced, data-driven assessment of earthquake risk.
This risk score is just a rough guide, not a guarantee. Earthquakes are unpredictable, and we’re not
responsible for how you use this info.
Think of it as a helpful snapshot, not a crystal ball.
