Significant Earthquake in World: 1970-2019
This visualization maps significant earthquakes from 1970 to 2019 on a world map, with bubble size encoding focal depth and color distinguishing tsunami-generating events. Hovering a point filters the display to that event type and reveals its coordinates. The React app uses d3.geoNaturalEarth1 and d3.geoPath to render landmasses from World Atlas TopoJSON, while d3.scaleSqrt and d3.scaleOrdinal map earthquake attributes. Data comes from the NOAA Significant Earthquake Database, loaded via d3.csv.
AI-generated descriptionThis is a visualization of the dataset National Geophysical Data Center / World Data Service (NGDC/WDS): Significant Earthquake Database. National Geophysical Data Center, NOAA significant earthquake database contains information on destructive earthquakes from 1970 to the present. The world map behind the points is a Mercator type map using the World Atlas TopoJSON. The points are off by a small fraction (down and to the left) however it fits much better on the Mercator projection over the Natural Earth projection. When the user hovers over each point, they can see the latitude and logitude of that deployment.
