Figure 1

From: Erratum to: S-wave attenuation in northeastern Sonora, Mexico, near the faults that ruptured during the earthquake of 3 May 1887 Mw 7.5

Figure 1

Examples of nonparametric attenuation functions obtained for 10 different frequencies. Black circles are observed horizontal S-wave spectral amplitudes for all magnitudes, open circles are observed vertical S-wave spectral amplitudes for all magnitudes. Black continuous line corresponds to the attenuation function found for the horizontal spectral amplitudes (cm/s2) and dashed line corresponds to the attenuation function found for the vertical component of the acceleration spectral amplitudes (cm/s2). This is the corrected Figure 6 in Villalobos-Escobar and Castro (2014).
