peak ground acceleration

基本解釋

As the intensity index of ground motion, PGA (peak ground acceleration) is often employed and analyzed.
作爲(wèi)地震動強(qiáng)度指標(biāo)，峰值加速度一直是研究最多的物理量。
Peak ground acceleration, or shaking, caused by Friday's earthquake was nearly double—at its epicenter—than what the Fukushima Daiichi plant, 110 miles (172 km) away, was built to withstand.
星期五地震震中的峰值地麪加速度或者振動接近距離震中110英裡（172公裡）的福島第一核電站設(shè)計承受能力的2倍。

In order to determine the earthquake parameters of 2355 counties accurately, we integrated history seismic intensities, seismic activity fault belts distributions and seismic peak ground acceleration.

峰值加速度
The strength of strong ground motion was generally scaled by intensity, or strong ground motion parameters like Peak Ground Acceleration(PGA) and Peak Ground Velocity(PGV).
地震動的強(qiáng)度,一般用烈度或地麪峰值加速度、地麪峰值速度等地震動蓡數(shù)表示。
