The Supposed Connection between Distant Earthquake Shocks

Abstract

IT is very commonly assumed, whenever seismic disturbances at different localities occur synchronously, that, however remotely they may be situated, there is necessarily a connection of some kind between the shocks, originating in a common cause. A forcible illustration of this fallacy, as I think, having recently appeared in your columns, I beg to take this opportunity of questioning the position so generally adopted, and of testing the validity of the involved theory of earthquake causation by the light of the evidence furnished in the concrete case which has been presented in support of it.
