This project is a part of my exploration of visualizing data with code through Processing, with this data-set I have tried to represent ~25000 entries over the years 1965 - 2016 in a Mercator projection world map for easy comprehension of the scale and time of said earthquake occurrences.
Part of the data-set used for visualizing the earthquakes; containing year, GPS coordinates, depth, magnitude and the USGS ID
Top 8 earthquakes with the highest magnitude have been illustrated with helping text for more information
Writing the code proved to be a challenge as the Richter scale is used for measuring earthquake magnitudes, and mapping those values to a dot leads to dots with indistinguishable sizes because of the Richter scale being logarithmic. After writing a function to convert the logarithmic scale to a linear scale it looks much more distinguishable.
The code I used for plotting the data on the map; written in Processing (Java)
Legend on the map showing the year of occurrence and magnitude represented by color and size respectively
