The United States Geological Survey (USGS), is responsible for providing scientific data about natural hazards, the health of ecosystems and environment and the impacts of climate and land-use change. Their scientists develop new methods and tools to supply timely, relevant and useful information about the Earth and its processes.
The USGS is interested in building a new set of tools that will allow them to visualize their earthquake data. They collect a massive amount of data from all over the world each day, but they lack a meaningful way of displaying it.
In this challenge, I was tasked with developing a way to visualize USGS data that will allow the USGS to better educate the public and other government organizations (and hopefully secure more funding) on issues facing our planet.

Part 1: Create the Earthquake Visualization
The first task is to visualize an earthquake dataset. The following steps were completed:
-
Obtained the 'All Month' earthquake data set. A JSON representation was provided to pull the data for the visualization. The following image is a sampling of earthquake data in JSON format:
-
Import and visualize the data by completing the following:
- Using Leaflet, create a map that plots all the earthquakes from the dataset based on logitude and latitude
- Data markers should reflect the magnitude of the earthquake by size and depth of the earthquake by colour
- Earthquakes with higher magnitudes should appear larger
- Earthquakes with greater depth should appear darker
- Popups with additional information about the earthquake when the associated marker is lcikced
- Created a legend that provided context for the map data
Below is an example:
Part 2: Gather and Plot More Data
Performed the following tasks:
- Plot the tectonic plates dataset on the map in addition to the earthquakes.
- Added other base maps to choose from.
- Put each dataset into separate overlays that can be turned on and off independently.
- Added layer controls to the map.
Below is an example:
Dataset created by the United States Geological Survey.
- Dataset provided by edX UofT Data Analytics, which had been generated by Trilogy Education Services, LLC.
