Seismite • SeismologySeismologists sometimes refer to a a pair of similarly sized earthquake shocks that occur relatively closely spaced in time and location as an earthquake "doublet." [1] This is distinct from the normal pattern of earthquake aftershocks.
The first earthquake can be some considerable distance and time away from the second.[2]
