●市街地近くに富士山噴火口　

富士吉田・雁ノ穴　専門家「避難エリア見直しを」

　富士吉田市の北富士演習場内にある「雁ノ穴（がんのあな）」で、国土交通省富士砂防事務所が富士山噴火で溶岩が噴出した形跡を確認していたことが２９日、分かった。同事務所の調査に助言した静岡大の小山真人教授が同日、富士吉田市内で開かれた火山災害をテーマにした研究会で明らかにした。雁ノ穴は道の駅富士吉田の約２キロ南西で市街地に近接しているが、富士山噴火に備えたハザードマップでは火口ができるエリアとして想定されていない。火山専門家からは「噴火の際は雁ノ穴周辺が火口になる可能性がある」として、避難エリアの見直しを求める声が上がっている。



・雁ノ穴　（富士吉田市）　溶岩が作った巨大洞穴

富士山噴火の名残をとどめる雁ノ穴の「崩れ穴」。ハイキングコースだが、訪れる人は少ない＝富士吉田市上吉田 　北富士演習場西側にあるアカマツ林の一角。約４ヘクタールの入会地に散らばる、２つの溶岩洞穴と１６カ所の溶岩樹型群を総称して「雁ノ穴（がんのあな）」と呼ぶ。１９３２（昭和７）年、国の天然記念物に指定されたが、同じ年には富士山頂で富士山測候所が通年観測を開始した。

　「市がハイキングコースの１つに挙げているけど、地元でも立ち寄る人は少ないですよ」とは、登山ガイドの近藤光一さん。溶岩樹型は縦穴が多いのが大きな特徴。１０メートル近い深さの穴もあるので、訪れる際には足場に注意が必要だ。

　「崩れ穴」は、溶岩洞穴（長さ５７メートル）の中央が崩落し、両端の洞穴が残ったもの。崩れた部分（溶岩溝）は、周囲よりも空気が冷たい。洞穴に入ると、天井部にぽっかりと穴が開き、差し込む陽光がまぶしい。穴は「噴火時にガスが噴出した痕跡」（近藤さん）という。

　演習場内にあるため、雁ノ穴周辺の散策は立ち入り日に限られる。地元住民以外は、富士吉田市外二ケ村恩賜県有財産保護組合（吉田恩組）で入山申請が必要。電話０５５５（２２）３３５５。

●富士山噴火　３０センチ超で避難呼び掛け　
降灰で初の基準　山静神３県

　富士山噴火に備えて広域的な防災対策を検討している山梨、静岡、神奈川の３県は７日までに、広域避難計画の骨子案をまとめた。溶岩流や降灰、土石流など４災害に分類し、避難対象エリアや避難開始の目安を示した。住民に加え、富士山が世界文化遺産に登録されたことで増加が見込まれる、登山者や観光客への対応も盛り込んだ。火山防災で降灰の避難基準を設けるのは全国で初めてで、火山灰が３０センチ以上積もると予想されるエリアで避難を呼び掛ける。
