Leaflet Earthquake Magnitude Map
A seismic-events map where each earthquake is a circle whose radius scales with magnitude (Richter scale, exponential) and whose color encodes depth (shallow → red, deep → blue) — the standard format used by USGS, EMSC, and seismology dashboards everywhere. Hover any circle for a

When to use this template
This visualization helps identify patterns in the spatial distribution, intensity, and subsurface characteristics of discrete events. Analysts use it to quickly discern areas of high activity, compare event magnitudes, and understand how a secondary quantitative dimension, like depth, correlates with location and primary intensity.
- Geospatial point data with latitude and longitude coordinates.
- Datasets where each point has a primary quantitative value for magnitude scaling.
- Datasets where each point has a secondary quantitative value for color encoding.
- Event-based data, representing distinct incidents rather than continuous fields.
- Data requiring visual differentiation of event intensity and a secondary attribute.
- Suitable for monitoring dynamic event streams or analyzing historical archives.
