震源近傍強震動の比較

中央気象台観測点での震源近傍域での最大加速度分布.(資料提供はMori先生)


中央気象台震源近傍域での最大加速度分布
最大速度分布
最大変位分布


中央気象台震源近傍域での最大加速度,最大速度の水平・上下動の比較.水平動の大きい方と上下動を比較している


震度分布(Wen教授からの情報に加えてTCU078&129の強震データから気象庁震度を計算)

Response Spectra (linear scale)



TUC129(984galの計測地点), TUC078の速度波形
及び神戸(海洋気象台),コジャエリ(SKRとの比較)

応答スペクトルの比較(神戸海洋気象台 VS SKRコジャエリ VS TUC129台湾)成分は全て東西動
台湾TCU129の情報はHP より絶対加速度応答スペク トル(Sa)(5%)で,神戸KOBとコジャエリSKRもSaを求めました.速度応答スペクトルはSaから計算された疑似速度応答スペクトル(5%)です.

Comparison between near-source ground motions

















Maximum acceleration distribution. Triangles show the station whose max. value information were released.
Max value means the maximum value of three component maximum values. Contours corrspond seismic intensity boundary.















Comparison bet. max. acc. of three components. Yellow dots show the Chelongpu fault (The earthquake occurred mainly on the active Chelongpu fault.).


















Comparison bet. max. vel. of three components. Yellow dots show the Chelongpu fault (The earthquake occurred mainly on the active Chelongpu fault.).
















Comparison bet. max. disp. of three components. Yellow dots show the Chelongpu fault (The earthquake occurred mainly on the active Chelongpu fault.).
















h Comparison bet. vertical and horizontal (larger values of EW and NS comp) components of acceleration and velocity.
