Fig. 9.

Temporal evolution of high-semblance data on average apparent slowness and back azimuth derived from the array analysis of vertical components. Circles show the average apparent slownesses or back azimuths that are calculated from two horizontal slowness values within 1-min time windows. Averages are calculated only for windows in which slowness values with semblance greater than or equal to 0.7 occurred 30 times or more. The gray scale inside the circles shows the average semblance value. Other symbols are the same as in Fig. 8.
