Summary of the result of MDC analysis. The location of preferred point source is shown in (a), accompanying with USGS PDE location (red star) on the base of ETOPO2 topography. The red focal mechanism shows the preferred MDC solution and the blue arrow denotes the strike of the inferred low angle fault plane. The azimuthal variation of ln(As/Ad) is shown in (b) with red triangles and green circles for vertical and transverse components. The station locations are summarized in (c) as black triangles. The dashed contours denote 60° and 120° iso-distances. The values of inverted parameters are summarized in (b) as well as the average variance reduction (VR) and number of traces.
