█ 概要

2007年3月25日9時41分に，能登半島沖を震源とするマグニチュード（Mw）6.7 の地震が発生し，石川県七尾市，輪島市，穴水町で震度6強を観測したほか，広い範囲で震度5弱以上を観測しました。この地震の深さは約10km，発震機構解は西北西―東南東方向に圧縮軸をもつ横ずれ成分を含む逆断層型であり，地殻内で発生した地震です。能登半島周辺では，1993年2月7日に珠洲市の北方沖でM6.6の地震が発生しましたが，その地震の発生機構解は北西―南東方向の圧縮軸による逆断層型¹⁾であり，今回の地震とほぼ同様のメカニズム解を示しています。

（深さは防災科研Hi-netシステムによる暫定処理結果，マグニチュード及びメカニズム解は防災科研F-netによる手動解析処理結果に基づく。また1993年能登地震の震源パラメーターは， YCU地震学レポートNo.20より引用）
