This paper describes investigation results on damage to building structures in/around Tacloban, Leyte, Philippines due to Typhoon Haiyan which occurred off the eastern coast of Leyte on 4/November/2013. Wind speeds at the investigated area are estimated from several damage samples, because the peak gust released by Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) seemed to be lower because of damage to meteorological instruments. Consequently, the wind speed estimated at Tanauan, Leyte attained to about 70 m/s. Moreover, typical constructions and damage observed at the investigated area are summarized to suggest a strategy to mitigate future disasters. Damage to structures might become more severe due to existences of jalousie window and/or ventilating louver which were commonly implemented in buildings in Philippines. Progressive collapses also seemed to happen in several damaged structures.
