Fig. 5From: Development of a detection method for short-term slow slip events using GNSS data and its application to the Nankai subduction zoneExample of the duration estimation in the case of the February 7, 2007 event. a Preprocessed and stacked time series. Black dots represent preprocessed time series of EW and NS components at stations 0301 and 3102. Red dots represent stacked time series assuming a duration of seven days. b Correlation coefficients of the stacked time series with varying durations. The pink solid line represents the duration that recorded the maximum correlation coefficient. c Frequency distribution of the duration obtained by the bootstrap resampling. Orange bars, a green solid line, and a green shade represent numbers of cases for each duration, the mode of the duration, and the 70% confidence interval, respectivelyBack to article page
