Kaisei Town in Kanagawa Prefecture, where up to 1,8500 people of the town's entire population will be evacuated in the event of a large-scale eruption of Mt. Fuji, was the first in the prefecture to formulate an evacuation plan for residents and announced it on the 1st. However, the specific evacuation destination has not yet been decided, and we would like to secure them in cooperation with the prefecture.

The hazard map assuming the eruption of Mt. Fuji has been revised and it is estimated that about 3,80 people live in the target areas in the three prefectures of Shizuoka, Yamanashi, and Kanagawa.

In Kaisei Town, Kanagawa Prefecture, where up to 1,8500 people are evacuated, lava flows may reach the entire town along the Sakakawa River over 6 to 18 days after the eruption, and volcanic ash may accumulate more than 30 centimeters.

Therefore, the town formulated an evacuation plan for the first time in the prefecture and announced its contents on January 1.

The plan states that evacuation will proceed in stages in each district based on the characteristics of lava flows reaching relatively slowly, and when the lava flows reach the national highway passing through Gotemba City, Shizuoka Prefecture, residents will be notified of the start time of evacuation, and evacuation instructions will be given when they reach the neighboring town of Yamakita.

In the northern part of the town, evacuation is expected to begin 3 days after the eruption, and in the southern part, evacuation is expected to begin 12 days after the eruption.

On the other hand, the evacuation destination has not been specifically decided, and depending on the scale of the eruption, coordination will be made with neighboring and local governments outside the prefecture.

A woman in her 50s from Kaisei Town said, "I have thought about what would happen if the river flooded, but I had never thought about the eruption of Mt. Fuji.

A woman in her 80s said, "I would like to see the evacuation plan."

Norinori Kasai, a specialist at the Kaisei Town Disaster Prevention and Safety Division, said, "Lava flows involve not only Kaisei Town but also other cities and towns, so it is necessary to cooperate and coordinate with neighboring municipalities. I also want you to prepare goggles and masks in case of ashfall."

If Mt. Fuji erupts and lava flows out, it is expected to reach three cities and four towns in Kanagawa Prefecture: Sagamihara City, Odawara City, Minamiashigara City, Kaisei Town, Matsuda Town, Oi Town, and Yamakita Town.

Kaisei Town has formulated an evacuation plan for the first time, but Matsuda Town is in the process of formulating it and hopes to announce it by the end of this fiscal year, and Minamiashigara City aims to formulate it by the end of this fiscal year.

For Yamakita Town and Oi Town, the specific timing of the formulation has not been decided.

Sagamihara City says that only a part of the area where the lava flow reaches will be reached, and that it will respond by setting up evacuation centers in the city, and there are no plans to formulate it.

Odawara City says that it is necessary to take into account the response of the prefecture, and has not decided whether or not to formulate it at this time.

On the other hand, specific evacuation destinations are a major issue, and even Kaisei Town, which announced an evacuation plan on January 3, may cross the prefectural border, so specific locations are not included.

In Yamanashi Prefecture, the prefecture and 4 municipalities in the prefecture signed an agreement in May last year, and in the event of a large-scale disaster such as an eruption, the prefecture will coordinate evacuation sites.

Many people in charge of cities and towns in Kanagawa Prefecture, where lava flows may reach, asked the prefecture to take the lead in coordination, saying, "In the case of wide-area evacuation across local governments, it is difficult for cities and towns alone to coordinate to secure evacuation sites."

Kanagawa Prefecture hopes to proceed with consultations with cities and towns to indicate the direction of wide-area evacuation as soon as possible.
