peak ground acceleration

基本解释

As the intensity index of ground motion, PGA (peak ground acceleration) is often employed and analyzed.
作为地震动强度指标，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面加速度或者振动接近距离震中110英里（172公里）的福岛第一核电站设计承受能力的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.
具体综合历史地震综合烈度、地震活动断裂带分布、地震动峰值加速度三方面来确定全国2355个县域单元的地震发生参数；

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).
地震动的强度,一般用烈度或地面峰值加速度、地面峰值速度等地震动参数表示。
