Mapping Earthquakes

Overview

• This analysis uses Leaflet and Mapbox JavaScript libraries to create an interactive map depicting earthquake data from the past 7 days.
• Accomplishing this task required using API requests to Mapbox, manipulating styles using the JavaScript Leaflet library, and using D3 to access GeoJSON data.

Results

• This analysis results in a dynamic map that toggles between 3 Mapbox styles:

  1. Streets
  2. Satellite
  3. Dark

• The map loads with all 3 layers displayed:

  1. Circles that mark the location of each earthquake from the past 7 days.
     • The color and size correspond to the magnitude, as described by the legend.
     • Data sourced from USGS.
  2. The tectonic plates.
  3. Circles that mark the the location of each earthquake with a magnitude of greater than 4.5.
     • The color and size correspond to the magnitude.
     • Data sourced from USGS

• Each layer can be toggled on or off individually:

Summary

• This analysis brings together API requests, JavaScript, and functional programming while visualizing data in a creative and attractive manner.

• Suggestions for improvement on this code:

  • The legend scale could be changed slightly to account for the earthquakes with a magnitude over 4.5.
