WebAlthough there have been numerous earthquakes with two or even three primary shocks of such similar magnitude that picking one as the main shock can be somewhat arbitrary, it was not until the 1970s and 1980s that studies of seismograms showed that some of these were not simply unusually large foreshocks and aftershocks.

In seismology, doublet earthquakes – and more generally, multiplet earthquakes – were originally identified as multiple earthquakes with nearly identical waveforms originating from the same location. They are now characterized as single earthquakes having two (or more) main shocks of similar magnitude, sometimes occurring within tens of seconds, but sometimes separated by years. The similarity of magnitude – often within 0.4 magnitude – distinguishes multiplet events … WebFeb 24, 2024 · a, Acceleration spectrogram for entire sol (top) and zoom around the event (bottom) with event start and end times ( utc) marked. b, Three component seismic channels in m/s (VBB, 20 sps) with MQS... nyt crossword band aid
