(A) Histogram of speeds (black dots) of all eruptions from May 15, 2010 to July 12, 2014. Eruptions appear to possess a power-law distribution near that of an inverse square (solid line). (B) A polar plot of the velocity vectors shows them to be reasonably isotropic with a maximum speed of 96.2 km/s. For clarity, only speeds over 10 km/s are displayed.
