Background

This site pulls data from the usgs Earthquake Hazards Program. Using global earthquake data from the past 7 days, each earthquake is mapped using Leaflet.

The Map

• The "default" map layer is from OpenStreetMap, the Topographic layer is from OpenTopoMap and the grayscale layer is from Stamen
• Marker size corresponds to the earthquake's magnitude.
• Marker color corresponds to the earthquake's depth - shallow quakes are yellow, and deep quakes are red, with colors interpolated sequentially in between.
• Each marker has a popup box with the following info:
  • Magnitude
  • Depth
  • Location Description (EG "24 km ENE of Krasnogorsk, Russia")
  • Coordinates
