“…Microtremor or ambient vibrations are de ned as vibrations with a displacement amplitude of roughly 0.1 to 1 micron and a velocity amplitude of 0.001 to 0.01 cm/s ( Okada & Suto, 2003;Choobbasti et al, 2015;Rezaei & Choobbasti, 2017) induced by both naturally occurring phenomena such as sea waves, earth's rotation and anthropogenic phenomena such as tra c movement and manufacturing machinery. By the measurement of such vibration one can predict ground response (Pandey, 2000;Paudyal et al, 2012), site ampli cation factor (Lu et al, 1992;Molnar et al, 2017), site classi cations (Kanlı et al, 2006;Sulistiawan et al, 2018), liquefaction (Choobbasti et al, 2015b;Huang & Tseng, 2002), and soil pro les (Cho et al, 2021;Karagoz et al, 2015;Ozep et al, 2004;Ridwan et al, 2014).…”
