2 地域の延焼危険度
地域の延焼危険度(町丁目単位)
横スクロールして確認できます。

概要

町丁目内で1件の建物火災が発生した場合、6時間後に平均でどの程度燃え広がるかを危険度のランクとして評価しました。
結果
- 特別区の西部では環状7号線と環状8号線に挟まれる地域やその沿線、中央線沿線等の地域で延焼危険度が高くなっています。
- 特別区の東部では明治通り沿いや荒川沿いの地域など延焼危険度が高い地域が点在しています。
- 多摩地域では、特別区との境界付近やJR中央線沿線の市街地をはじめとした地域で延焼危険度が高くなっています。
- 木造や防火造建物が密集している地域、広幅員道路や空地が少ない地域では延焼危険度が高くなる傾向があります。
地域の延焼危険度(250mメッシュ単位)
横スクロールして確認できます。

概要
250mメッシュ内に1件の建物火災が発生した場合の6時間後の延焼面積と出火可能性を同時に考慮して危険度のランクとして評価しました。
結果
- 延焼危険度(250mメッシュ)が高い地域は、地域の延焼危険度(町丁目)と同様ですが、河川敷や公園などの空地の多い地域で危険度が低くなっています。
- 宅地開発などで住宅が短期間で増加した地域で従来よりも延焼危険度が高くなっている傾向にあります。
区市町村別延焼危険度一覧表
出火から6時間後の延焼面積の平均値を区市町村ごとに求め、延焼危険度のランクで評価しました。
また、メッシュごとの延焼危険度ランクを区市町村ごとに集計し、それぞれの割合(%)を求めました。
なお、消防署管轄別延焼危険度一覧表は、この表と同様にして消防署管轄ごとに集計したものです。

2つ以上の消防署管轄にかかるメッシュについては、代表的な管轄の集計に含めています。
割合は小数点以下第二位を四捨五入した値です。
延焼危険度の推移(250mメッシュ単位)
横スクロールして確認できます。

概要
250mメッシュごとの地域の延焼危険度を前回(第9回)と比較したものです。市街地の変化等による危険性の変化を表しています。
危険度が増加する要因としては、空地等の宅地化による住宅の増加、建替えによる密集度の増加などが挙げられます。また、GISデータの精度が向上したことによって、より実際の市街地に即した危険度の判定が可能となったことで精緻な結果が得られています。
結果
- 全体として延焼危険度に大きな変化は見られませんでしたが、一部の地域で2の増加が見られました。
- 特別区では、練馬区、世田谷区、大田区、などをはじめとした地域で延焼危険度が増加している状況がみられます。住宅の増加等で延焼が広がりやすくなったことが主な要因です。
- 多摩地区では、新しく住宅街が形成された地域などで延焼危険度が高くなっています。
