Figure 2From: Crustal structure in the northwestern part of the Izu collision zone in central JapanSeismic records of SP1 (top), SP3 (middle), and SP5 (bottom). Each trace is normalized by its maximum amplitude. Reduction velocity is 6 km/s. A 1- to 15-Hz band-pass filter is applied for SP1 and SP3. A 10- to 20-Hz band-pass filter is applied for SP5.Back to article page
