ground quiver meaning in English

地上箭筒

And as for the vague something - was it a sinister or a sorrowful , a designing or a desponding expression ? - that opened upon a careful observer , now and then , in his eye , and closed again before one could fathom the strange depth partially disclosed ; that something which used to make me fear and shrink , as if i had been wandering amongst volcanic - looking hills , and had suddenly felt the ground quiver and seen it gape : that something , i , at intervals , beheld still ; and with throbbing heart , but not with palsied nerves
至于那种令人难以捉摸的东西那种表情是阴险还是忧伤，是工于心计还是颓唐沮丧，一个细心的旁观者会看到这种表情不时从他目光中流露出来，但是没等你探测暴露部分的神秘深渊，它又再次掩盖起来了。那种神态过去曾使我畏惧和退缩，仿佛徘徊在火山似的群山之中，突然感到大地颤抖，看到地面裂开了，间或我还能见到这样的表情，我依旧怦然心动，却并未神经麻木。
