Sliding windows RQA for station KAIK. The sliding window is 100Â days wide with an overlap between windows of 50Â days. The main displacement event occcurs in the 50Â day window following the red star. For an RQA measure to be a useful precursor it should depart by a factor of two or more from the mean of that measure 100Â days (two black dots) before the main event. a Mean. b Standard deviation. c %REC. d %DET. e DMAX. f ENT. g TREND. h %LAM. i VMAX. j TTIME
