A few years ago, ESRI's Raluca Nicola created a stunning 3D visualization titled Earthquakes with Exaggerated Depth, illustrating how far below the surface earthquake ruptures (hypocenters) occur. Her interactive globe visualizes one year's worth of earthquake activity worldwide (from July 2017 to July 2018).
The map was created using data from the USGS. On the 3D interactive globe, each earthquake is represented by a colored circular marker, with color and size indicating the earthquake's magnitude. The depth of each earthquake is visualized with an exaggerated scale, magnified by a factor of eight.
Now, you can explore a near real-time 3D map displaying the locations and depths of the most recent earthquakes worldwide. The 3D Earthquake Globe Visualization was developed using Three.js to render an interactive, transparent Earth model with exaggerated depth markers.
The map fetches real-time earthquake data from an API endpoint, plotting each quake as a colored line -where hue represents magnitude and length signifies depth. Detailed information on each earthquake is displayed on hover. The visualization features a main globe view with auto-rotation controls and a secondary, Japan-focused seismic view. Both views depict Earth's internal layers, from the crust to the core.
The user interface includes interactive controls for rotation, depth scaling, layer visibility, and globe opacity, providing an intuitive and immersive experience.
