Figure 12From: Seismic activity near the Moriyoshi-zan volcano in Akita Prefecture, northeastern Japan: implications for geofluid migration and a midcrustal geofluid reservoirExample fitting of single isotropic scattering model to seismogram envelopes. The raw three-component seismograms are shown at the top. Lower panels show band-pass filtered seismograms and theoretical envelopes (red lines) for five frequency bands: 1, 2, 4, 8, and 16Â Hz.Back to article page
