This map visualizes global earthquake activity from the past week, highlighting that most events cluster along tectonic plate boundaries, particularly around the Pacific Ocean. Circle size corresponds to magnitude, while color indicates depth category (shallow, intermediate, deep). The visualization uses D3’s geoEquirectangular projection, fetch and json for loading data from the USGS earthquake feed and tectonic plate GeoJSON, and includes dropdown menus to filter by depth and magnitude. Users can click circles to open earthquake detail pages, drag to rotate the globe, and zoom via D3’s zoom and drag interactions.
