This movie shows two animated representations of earthquakes in The Geysers geothermal reservoir. In the first, seismic data has been turned to sound, with bigger, deeper earthquakes registering as louder and duller. The sizes of dots and their colors represent the magnitude and depth of each quake. In the second,, the frequency content of the original seismic data has been analyzed with machine learning algorithms. The algorithms clustered the earthquakes into similar types, which the researchers related to fluid injection rates into the reservoir. Each color represents a cluster type and its associated tone, which was synthetically produced. The tone of the clicks represents the relative fluid injection rate, and the music, the temporal transitions between clusters and their relation to injection rate.
