Volcanic Information and Response of Local Authorities in Case of the 2006 Sakurajima Eruption

Abstract

2006年6月に桜島の中腹の昭和火口から突如噴火がはじまり，約1ヶ月間噴火活動が続いた。火砕流の発生が懸念されたが，ごく小規模なものであった。本稿は，この活動に関連した火山情報と地元関係機関の防災対応について解説している。関係機関の連携のもと円滑な防災対応がなされた背景には，桜島のハザードマップ作成等の共同作業を通じて得られた火山活動に関する知識の共有がある。

In June 2006, eruption abruptly occurred on the eastern slope of Sakurajima volcano, and activity continued for a month. It was anxious that the activity might be accompanied with pyroclastic flows, but the actual flows were minor. This manuscript describes volcanic information and countermeasures done by local authorities related to this short-term volcano crisis. Quick response of local governments and sooth decision of countermeasures among several organizations were achieved under common understanding on volcanic activity.
