Fig. 3From: Fault extent of the largest aftershock of the 1968 Tokachi-Oki, Japan, earthquake and an interpretation of the normal faulting focal mechanismCumulative power curves of 5 to 10 Hz band-pass filtered accelerograms. The arrows show the time when the cumulative power is 0.1 and/or 0.9. Strong motion duration is defined as the time interval for the cumulative power to increase from 0.1 to 0.9.Back to article page
