圖片介紹: 我第一次聽見的地鳴聲跟此影片中的有某程度相似，但此影片中的畢竟只是錄音，大家聽時要想像成自己是在現場，這種聲音當場環繞你、或朝你的方向襲來的感覺，才有可能感受為什麼我說這種聲音是 "被蒙住的、悶悶的氣勢磅礡聲"。欲看此影片，請點擊圖片。Illustration: The subterranean-rumbling sound I heard for my first time resembles the recording sound in this news clip to some extent; nevertheless, the sound in this news clip is just recording after all, so when you hear it, imagine you were on the spot, and this sound surrounds you or sweeps towards you, then chances are that you might understand why I describe the sound as "loud rumbling sound of great momentum being muffled".
