Map view, fault perpendicular, and fault longitudinal cross sections of real-time double-difference locations of the mainshock and its aftershocks (colored dots and circles). Gray dots and circles represent high-res background seismicity. Circle size in B-B` is proportional to magntiude for 3 MPa stress drop source. Squares in map view show routine network locations for comparison. Green lines in map view are fault traces. Click on figure to zoom in.
