Earth movement

planned

Magnitude, epicentre, depth, and shaking actually experienced at a location.

Authoritative sources exist and publish continuously. Adapter not built.

What this lane covers

Magnitude, epicentre and depth

The located event and its size.

event areal analysis

Peak ground acceleration

Acceleration recorded at an instrument.

measurement station instrument

Shaking intensity at a location

Modelled intensity at a place from the located event.

model areal analysis

How to read this page

event

Someone recorded that a thing happened. An observation, not a reading.

measurement

An instrument read a value at a place and a time.

model

An analyst or a model produced this from other data. It is a product, not a sensor.

areal

Covers an area, not a point. There is no nearest station, and we will not invent one.

station

Measured at a fixed station. The record discloses which one and how far it is from you.

analysis

An authoritative body's analytical product. Its uncertainty is the source's own.

instrument

Published by an authoritative operator of the instrument.

What we cannot compare

Magnitude is a property of the event; shaking is a property of your address. Parametric triggers are written against the second and argued using the first, which is exactly where the money is.

Sources

Not named here yet. Candidate sources for this lane exist and are identified internally, but they have not been verified against the primary documentation — and an unverified source attribution on a public page is the exact mistake this company exists to avoid. They appear here when they have been checked, not before.

Where the answer is worth money

Structural damage attributed to an event. Induced seismicity near injection wells. A parametric policy triggering on ground motion at the insured site rather than at the epicentre.

That framing is our analysis of where disputes arise, not a claim of fact about any matter.

Not captured yet

What would you need from earth movement?

We are not capturing this lane today, so there is nothing here to sell you and we are not going to pretend otherwise. What we do want is to know what you would actually ask it. Requests decide what gets built next — that is not a courtesy, it is how the order is set.
