Introduction

As a new member of the United States Geological Survey (USGS), I have been tasked with building an map that allows the team to visualize their earthquake data.

Objectives

Visualize a selected earthquake dataset by:

• Picking a dataset from the USGS GeoJSON feed
• Creating a map using Leaflet the plots all earthquake locations
• Adjusting marker size using the magnitude value
• Adjusting marker color using the depth value
• Adding popups that provide magnitude, location, and depth of the earthquake
• Creating a legend that gives meaning to the marker color
• Adding layer controls

Technologies & Sources

This project uses:

• Javascript
• CSS
• HTML
• D3.json
• Leaflet

Files & Links

• Selected Data: GeoJSON data used for my map (earthquakes over last 30 days with a minimum magnitude of 4.5)
• Javascript File: file containing all javascript code used for reading in the GeoJSON data and creating the map using Leaflet
• Style File: style for map page
• Map HTML: HTML for the map page, which is created using Leaflet, D3, and Javascript dynamic coding
