Abstract

Comparison between ZnBZ, WnC, and TMC clustering methods for NEIC catalog. Upper rows in each panel show map views of the seismicity (M≥5.0) with background events (gray) that occurred prior to the mainshock (triangles) or after (circles). The identified foreshocks are plotted in blue (triangles) and aftershocks in red (circles). The magenta circles represent the effective radius of the mainshock (see Eq. 1). Focal mechanism solution of the mainshock is from the GCMT catalog.  Time lines, with nonlinear scale are shown for the seismicity in each map as functions of magnitude (middle row of each panel) and epicentral distance from the mainshock* (lower row of each panel), with the same color scheme.</p
