This repository demonstrates basic Modified Mercalli Intensity (MMI) calculations in Go. The mmi package implements several empirical intensity prediction equations (IPEs) based on published studies, and main.go provides a small example that prints the predicted intensity for a given magnitude and distance.

The mmi package contains Go implementations of the following MMI models:

• Bakun & Wentworth (1997) – calibrated for Californian events
• Atkinson & Wald (2007) – recommended for near‑source distances
• Allen & Wald (2012) – global active‑crust model

A helper function BestEstimate chooses between these equations based on simple distance heuristics.

Go modules are used, so Go automatically resolves dependencies. To build the example program run:

go build

This creates an executable named goeew in the current directory. You can then run it directly:

./goeew

Alternatively, you can run the example without building a binary using:

go run .

The program prints the predicted MMI values for each model and a best estimate for the magnitude and distance hard‑coded in main.go.
