From: ‘Negative repeating doublets’ in an aftershock sequence
Earthquake doublets recorded at the WCH station. Blue circles indicate the doublets with positive correlation coefficients, while red dots indicate the ‘negative doublets’. Red circles show the 2 events which have both ‘positive repeater/s’ and ‘negative repeater/s’. Parameters (as registered in the seismological network bulletins) of these 2 events and their ‘positive repeaters’ and ‘negative repeaters’ are:
