本論文は，2016年4月14日の熊本地震の前震と4月16日の本震による液状化発生地点の分布と被害状況を示すと共に，液状化の発生と地震マグニチュード，地震動強さ，微地形区分，土地条件との関係について検討している．液状化の発生は，熊本県下の18市町村に及び，熊本平野と阿蘇カルデラ内の低地に集中していた．本震の震央から最も遠い液状化地点の震央距離42.6kmであり，過去の地震における液状化と比較して小さめの震央距離だった．250mメッシュ単位の推定震度分布との関係を調べた結果，前震・本震共に液状化が発生したメッシュの99.9%以上が推定震度5強以上の地域であった．液状化発生地点の微地形区分は，熊本平野では後背湿地・自然堤防などの河川の氾濫原のほか干拓地で多かった．阿蘇地域では，後背湿地と阿蘇火山山麓に広がる扇状地で多かった．液状化発生が集中した地域における土地条件を調べた結果，河川の氾濫，地形改変履歴，埋土・盛土とその材料，砂利採掘履歴，地下水条件が液状化の発生に大きく影響していたと推察された．

Our investigation revealed that the earthquake induced liquefaction at a significant number of locations in a 80-km long zone extending along the earthquake source faults. This paper presents distribution of the liquefied sites and their effects on buildings and infrastructures during the earthquake. Additionally, the distance from the epicenter to the farthest liquefied site is compared with previous Japanese earthquakes, and intensities of ground motion that caused liquefaction are discussed. Finally, land conditions where severe and widespread liquefaction occurred are investigated.
