For slip distributions characterized by the von Kármán-type power spectral density, we examine the dependence of the estimated energy release on the upper limit and decay rate of the power spectral density in the shorter wavelength band. Using this dependence, we quantify the potential underestimation of energy release when the wavelength band limitation is not considered or the k−2 model is incorrectly assumed. Moreover, we discuss the estimation of radiated energy with respect to high-frequency components and suggest a relationship between stress drop heterogeneity and high-frequency radiation.}, pages = {1585--1592}, title = {Dependence of seismic and radiated energy on shorter wavelength components}, volume = {209}, year = {2017}, yomi = {ヤギ, ユウジ} }
