- Abstract:
- The strong motion records obtained by the Japan K-net and Kik-net strong motion network during the 2016 MW 7.0 Kumamoto earthquake were collected and processed. The characteristics of peak ground acceleration(PGA)and peak ground velocity(PGV)were analyzed. Then,the observation results were compared with three attenuation relationship formulas commonly used in Japan. Finally,the characteristics of significant duration and of frequency spectrum were analyzed. The results show that:(1)The PGA of EW,NS,UD component is 1 156.95 gal,-786.60 gal,874.40 gal,respectively. The observed PGA and PGV consistent well with the PGA and PGV attenuation formulas commonly used in Japan.(2)The 5% ～ 75% significant duration and 5% ～ 95% significant duration were calculated,the significant duration grow with the epicenter distance in the whole.(3)The acceleration response spectrum of KMMH16 station exceeded those obtained by the JR Takatori station trigged during the 1995 Kobe earthquake in the 0.5～1.2 s period range. It will cause server damage to wooden houses and low to mid-rise reinforced concrete buildings.
