976 Alea landslide

Landslide is one of two types of land movements considered and mapped at Mayotte. It is a gravitary movement of a volume of movable soil on a slope and can mobilise a few m³ to several hundred thousand m³. These phenomena can be rapid or slow, earthworks, the presence of water and earthquakes can be triggers of these slips.滑坡是马约特岛被纳入研究与制图范畴的两类地表运动之一。其本质为斜坡上可移动土体的重力驱动运动，滑移体积可从数立方米延伸至数十万立方米。此类现象可分为高速与低速两类，土方作业、水体赋存以及地震均可作为此类滑坡的诱发因素。
