Don't relax! In the past, landslides occurred hours after the rain stopped.

Even if the rain stops or weakens, it is forbidden to immediately relax your alertness to disasters.

In the past, there were cases where landslides occurred several hours after the rain had weakened or stopped, causing casualties, and river flooding occurred after the heavy rain special warning was lifted. In some cases, it was damaged.

Sediment disaster after a few hours

In 1997, about 4 hours after the rain stopped, a large-scale debris flow suddenly occurred in the Harihara district of Izumi City, Kagoshima Prefecture, killing 21 people.

Some of the dead were evacuated during the rain, but stopped and returned home.

In the heavy rains in western Japan three years ago, debris flow occurred upstream of the Eno River, which flows through Fuchu Town, Hiroshima Prefecture, as the weather recovered and restoration work proceeded, causing debris flow into the houses.

Due to the rain so far, the ground has become loose with a large amount of water on mountain slopes and cliffs.

Recognize that the risk of sediment-related disasters remains extremely high, as water in the soil does not drain immediately.

If you live near a slope, never force yourself to go home.

The river overflows after the special warning is lifted

In some cases, the river overflowed after the heavy rain special warning was lifted.

After the heavy rain special warning was lifted, the Ototoshi Typhoon No. 19 flooded several rivers, including the Chikuma River in Nagano Prefecture and the Yoshida River in Miyagi Prefecture.

According to NHK's interview, several people have been confirmed to have been inundated due to flooding after returning to their homes after the heavy rain special warning was lifted.

Earlier, in prefectures where the special warning was canceled, there are rivers that exceed the "flooding danger water level", which has a high risk of flooding. Since there is a time lag between the rain falling on mountains and the like flowing into the river and the water level changing, the water level of the nearby river may rise in the future. Do not judge the danger of a disaster only by the intensity of rain, but check the water level carefully by referring to the website of the Ministry of Land, Infrastructure, Transport and Tourism and local governments at a place away from the river.

The effects of heavy rain will last for a long time. Please follow the evacuation information of the local government and spend a while in a safe place.
