## Overview

This repository is a Japanese-prefecture earthquake-risk web application: users choose a prefecture or enter coordinates, request a prediction, and view risk insights. The documented runtime pairs a static browser interface with an R Plumber API and a trained Random Forest model; the map also consumes USGS events and uses OpenStreetMap tiles. The README documents these capabilities and connections, but no source excerpts were available to verify finer-grained frontend or API behavior.
