- The purpose of this project is to visually show the differences between the magnitudes of earthquakes all over the world for the last seven days.
- It use a URL for GeoJSON earthquake data from the USGS website and retrieve geographical coordinates and the magnitudes of earthquakes for the last seven days. Then add the data to a map.
- In this project we use the JavaScript and the D3.js library to retrieve the coordinates and magnitudes of the earthquakes from the GeoJSON data. We then use the Leaflet library to plot the data on a Mapbox map through an API request and create interactivity for the earthquake data.
The display below shows the map of earthquakes of varying magnitude around the world in the past 7 days along with the tectonic plate. The color and the size of the circles indicate the magnitude and the depth of the earthquake, respectively. The legend in the bottom right side of the map corresponds to the earthquakes magnitude. The orange lines indicate the tectonic plates. The earthquake GeoJSON data was taken from, https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_week.geojson and the tectonic plate GeoJSON data was taken from, https://raw.githubusercontent.com/fraxen/tectonicplates/master/GeoJSON/PB2002_boundaries.json
The display below shows the map of major earthquakes with a magnitude greater than 4.5 around the world in the past 7 days. The major earthquake GeoJSON data was taken from, https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/4.5_week.geojson
The display below shows a third map style (Dark) added to the above map.
