Data backbone · Earthquake shakemap
How hard the ground shook, everywhere at once.
A magnitude number is one figure for an event felt across hundreds of kilometers. A shakemap turns it into what actually matters — ground-shaking intensity at every point — so within minutes of an event you know where to look first.

What's inside
- Intensity (MMI)Modeled shaking severity from the epicenter outward, on the felt-intensity scale.
- Peak ground accelerationThe engineering measure that structures actually respond to.
- Epicenter & fault contextLocation, depth, and the fault geometry behind the event.
- Rapid post-event updateGenerated fast, then refined as observations arrive.
Where it's used
- Insurance loss estimation
Exposure crossed with shaking gives a first loss picture in minutes.
- Emergency response
Triage the map — the worst-shaken areas get eyes and resources first.
- Structural risk
Which assets saw accelerations they were never designed for.
Minutes matter — so this runs on the backbone.
Because it's part of an engine we operate ourselves, a shakemap isn't a report you wait for — it's a layer that's ready the moment the ground moves.
