Blog Post Image: Mine Landslide Triggered Quakes

This spectrogram of a seismic recording shows four peaks in red and orange. The first, wider peak represents the low rumbling of the second rock avalanche in the massive Bingham Canyon Mine landslide in Utah on April 10, 2013. The three sharper peaks are from three of the small earthquakes that were triggered by the slide, which likely was the largest nonvolcanic landslide in modern North American history.
