Another reason is that kids are notoriously bad at shoring up the sides of deep holes, resulting in inevitable cave-ins once they reach a depth of six inches.

另外，小孩子在挖坑洞时，不会稳固洞旁的土，所以差不多15公分深时，凹洞免不了就塌陷了。

The plane shapes of ground collapse hazard mostly appear as round, ellipse, rectangle and irregular shape etc.

其中人为塌陷包括抽排水塌陷及采空区塌陷。
