Plot of earthquake epicentre depths in the map area, projected onto the latitude of 48°15'.
Red dots are events from the subducting slab of the Juan de Fuca Plate, white dots are from crustal events in the North American Plate.

Histogram showing the distribution of earthquake magnitudes for crustal events in the eastern Juan de Fuca Strait.
