Note, colors represent earthquake depths. Red is shallow (0-10km), yellow/green is mid-range (10-30km) and blue is deep (>30km). Most quakes are approximately 10km below the seafloor. Circles in the map are sized by earthquake magnitude, which range from 2.5-7.0. The box denotes the regions where earthquakes are available for plotting.
