一股黏稠的泥浆挟裹着巨大的石块,像山洪一般,以排山倒海之势,沿着峡谷奔泻而出,但见泥浆飞溅,山谷轰鸣。顿时,在山外堆积成一片泥浆石块的海洋。这就是泥石流突然暴发时的那种景象。泥石流常常发生在温带或半干旱地区的山区里,这种洪流最快时甚至可以每秒10米的速度前进,上千 A viscous mud was covered in huge rocks, like a mountain torrent, and rushing out along the canyon with the mountains, but seeing the mud splashing and the valley roaring.

Debris flow often occurs in the temperate or semi-arid areas of the mountainous region. When this flood is fastest, it can even proceed at a speed of 10 meters per second.
