Live Earthquakes Near Japan
Map a public USGS GeoJSON feed and style earthquake points by magnitude, depth, or significance.
Workflow
Size by magnitude
The feed includes a numeric 'mag' field for earthquake magnitude. Attach magnitude to point size so stronger earthquakes stand out, then use color or opacity for another field such as depth.
Add graticules
This regional earthquake graphic benefits from visible latitude and longitude lines. Turn on graticules and set the interval to 5 degrees so readers can better understand where the quakes are located.
Label selectively
Labels should add context without cluttering the map. Turn on labels for useful place names or notable records and let collision handling keep them readable.
