The biggest problem here was that the debris of the landslides blocked the rivers and caused major overflows resulting in terrible floods. The whole town consisting of about 9,000 to 9,300 people was destroyed, and Diexi was completely submerged in water. The landslide exposed the dacite magma in St. Helens neck to much lower pressure, causing the gas-charged, partially molten rock and high-pressure steam above it to explode a few seconds after the landslide started. The gravitational pull that facilitates a collective movement of soil, rock, and debris down a steep slope is called a landslide. The mushrooming of hydroelectric dams in Uttarakhand was also another important factor held responsible for the environmental damage.

When newly built in 1963, the Vajont Dam in Italy was the tallest in the world but building the dam proved fatal as it activated strong seismic activity. The flow broadened as it reached the main Obi-Kabud River valley, sweeping through part of Khait, crossing the river, before climbing a 25 m high terrace on the river's western bank and continuing a further 700 m, overwhelming the village of Khisorak. The volcanic flow melted the glaciers in the mountain sending devastating lahars concentrated with volcanic debris of ice, snow, and mud.
