Fig. 2From: Source characteristics of moderate-to-strong earthquakes in the Nantou area, Taiwan: insight from strong ground motion simulationsObserved source spectral ratios of stations used for the source modeling (thin gray lines), the average observed source spectral ratios (thick black lines) and fitting source spectral ratio function (red lines) for a E1, b E2, c E3, d E4, e E5 and f E6 events, respectively. Solid and open triangles show stations used in the source spectral ratio analysis and forward EGF simulation for each event, respectivelyBack to article page
