Depth and geographical distribution of deep-focus earthquakes

Abstract

Early in the history of seismology it was occasionally suggested that, in addition to earthquakes with foci comparatively near the surface of the earth, shocks might also originate at depths of the order of several hundred kilometers. However, down to a comparatively recent date, all such conclusions were either purely speculative or were based on inadequate or misinterpreted data.
