Strong earthquakes occurred in the southern part of Kyushu Island twice on February 21 and once on February 22, 1968. It was reported that about 400 dwelling houses totally collapsed in Ebino-machi and its vicinity. This report describes the damage to buildings in the disaster area where the writers visited to investigate the damage during February 22 to 27. The results of the investigation are summarized as follows: 1) It was observed that most of the damaged wooden houses had small lateral resistivity such as no bracing and heavy roof with tiles. 2) Land slides caused severe damage to wooden houses in some areas where the volcanic ash was deposited and weathered. 3) Some reinforced concrete buildings in the disaster area suffered almost no structural damage, while two concrete block buildings were heavily damaged, being supposedly due to bad construction work.
