Fig. 5From: Seismic velocity decrease and recovery related to earthquake swarms in a geothermal area(a) Cross section showing hypocenters of earthquakes along line A–B in Fig. 1 with isochronal curves for backscattered P-waves (dash-dotted line) and S-waves (solid line) from the OITA2 station at lag times of 6, 8, and 10 s. (b) A schematic illustration of the proposed model of the velocity change mechanism.Back to article page
