These influences are calculated by dividing the spectrum of the horizontal component by the spectrum of the vertical component (i.e., horizontal‐to‐vertical [H/V] spectral ratio [HVSR]) of microtremors or earthquake motions. Each element of the method had originated in Japanese publications (e.g., Nakamura and Saito, 1983), and then summarized in English articles (Nakamura, 1989, 2000, 2008, 2009). Although the applicably of the Nakamura method has been widely cited, there still exists a fundamental misconception...
