Fig. 14

Same as Fig. 8 for the wave speed models and waveforms for the extra shallow event (Feb. 19, 2012; M _W 4.9). a Source and receiver. b Vertical cross section of V _s for m ₀₀ and m ₁₆. c Vertical cross section of the difference between the V _s values for m ₀₀ and m ₁₆. d Waveform comparisons. The gray areas in (b) and (c) indicate areas of low data coverage. The crosses and inverted triangles in (b) and (c) show the location of the earthquake and station in (a), respectively. The black, blue, and red lines in (d) indicate the observed, m ₀₀, and m ₁₆ waveforms, respectively
