Developed at NASA Ames Research Center
with the WorldWind Development Team.
Powered by the USGS Earthquake API.
This is an earthquake visualization app built in NASA Web World Wind with support from the
Center for Earth Science. Given the wealth of USGS information on historic earthquakes, we designed
and built an app that can aggregate and display nearly 100 years of seismic data dynamically.
Quake Hunter is a valuable tool for understanding how tectonic plates interact with one another. Quake
Hunter visualizes any range of earthquake data from the USGS, in 3D, either on the whole planet or in a
user-defined geographically constrained area.
With powerful querying tools, this application provids exactly what the user wants to see in terms of
earthquake event data around the world.
Tour the events using the bottom two arrow buttons. Change how you tour the
earthquakes, either by magnitude or time by selecting the color mode in the controls menu.
Use the 'from' and 'to' calendar fill-ins to change the date range of the
earthquakes visualized (this can be done all the way back to 1925).
The magnitude slider allows you to filter how large the earthquakes being
Use the 'draw' function to draw rectangles or circles to geographically
constrain the query on earthquake events.
Search a radius of a specific location. Try Kodiak, Alaska! (57.7900,
The app should automatically generate a visualization of earthquake event
The reset button reverts the earthquakes displayed to the initial query.
Try a geographically constrained query along a subduction zone or fault line
(These are represented by the brown lines).
Set a specific sector of the planet to query earthquakes within.
Visualize a longer period of earthquakes (>20 years) and within the magnitude
Use the canvas controls (in the bottom left-hand corner) to change the angle of
viewing. This should provide a great visualization of how the tectonic plates interact with one another,
whether in a subduction zone, transform fault,
rift zone, or a hotspot.
Browse through the statistics of your query in the right hand side information
and graphs panel. Magnitude and depth histograms, as well an earthquake activity time series graphs are
all automatically generated from your query.
You can download these graphs by clicking the camera button in the upper right
hand corner of the graph plot area.
If the earthquakes are not loading immediately after you enter search parameters, it may be loading.
Look in the "Globe Options" to see if the "earthquakes" layer is loading. If the search involves in
excess of 5000 earthquakes, the load may take a while.
If you continually run into performance issues, consider using Google Chrome or Apple Safari to run the
Try removing the tectonic plate layer for improved browsing speeds in the app.
Consider limiting the earthquake event search to less than 2000 events for quicker load times
For larger queries, the performance greatly improves if searches are geographically constrained. To do
this, use the drawing tool to limit where earthquakes are shown.
