x402
Global Hazards Mercalli Intensity Scale Lookup is a paid API for AI agents from global-hazards.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).
Returns Modified Mercalli Intensity (MMI) scale descriptions including what is felt, typical damage, and shaking characteristics for a given intensity level (I–XII), or maps a peak ground acceleration (PGA) value to its corresponding intensity band.

How this service works
Modified Mercalli intensity I to XII: what is felt and the typical damage, or the intensity band for a peak ground acceleration.
Output
Returns a structured object with the numeric intensity level, Roman numeral (e.g. VIII), shaking description, summary of what people feel, typical damage description, and a verdict. When queried by PGA, returns the matching instrumental intensity band. Optionally includes source, disclaimer, and data freshness fields.
Example use cases
Earthquake damage briefing for emergency planners
“We just had an earthquake and USGS says the max intensity was MMI VII — can you tell me exactly what that means in terms of what people felt and what kind of structural damage to expect?”
PGA to intensity conversion for engineering report
“I have a site with a design peak ground acceleration of 65 percent g — what Modified Mercalli intensity band does that correspond to?”
Public education on Mercalli scale levels
“Can you give me the full list of all Modified Mercalli intensity levels from I to XII with descriptions of what each level feels like and what damage it causes?”
Technical details
Endpoint
GEThttps://global-hazards.x402tookit.com/mercalli-scale?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative human-readable descriptions of Modified Mercalli intensity levels — what people feel, structural damage, and shaking characteristics — or when you need to convert a peak ground acceleration value to an instrumental intensity band. Prefer this over generic earthquake magnitude lookups when the user needs intensity-based impact descriptions rather than raw seismic energy metrics.
Side effects
- Invalid intensity value outside 1–12 range returns an error
- Non-numeric string passed as pgaPercentG causes a validation error
- Omitting both intensity and pgaPercentG returns all levels (may return large payload)
- Service degraded flag set to true indicates partial or cached data
