A house made of sandwich panels was damaged as if crumpled.

The sediment collapsed in the heavy rain hit the house under the mountain.

Earlier on the 3rd, an old couple disappeared in Asan, Chungcheongnam-do, as they were swept away by a landslide.

Due to the record rainy season, damage is increasing as the entire country, except Jeju, enters areas at risk of landslides.

The problem is the occurrence of landslides where the soil can no longer absorb rainwater and the soil layer collapses.

As a result of the experiment, when only the soil collapses, 2 tons of force acts, whereas when the stones are mixed, 5 tons of destructive power is more than doubled.

This is why landslides, aka'soil and pomegranate,' where soil and stones are mixed and flowing down are dangerous.

[Seo Jeong-il/Professor, Department of Forest Science, Gongju University (Landslide Investigation Director): The speed of the earth and stone flows is 20 to 40 km/h, and if the earth and stone flows occur and I am in a valley, it is almost impossible to avoid... .]

If the house is built of a weak material, such as a sandwich panel, there is a greater likelihood of human damage from earth and stone flow.

mountains It is recommended that nearby residents do not approach down the slope at all, and check emergency letters and disaster broadcasts regularly and evacuate to a nearby shelter immediately if an evacuation order is issued.
