MVSMMP Maps 25-27: Long Period Amplification Hazard (2475-year-Return-Period equivalent)

This is a package of MVSMMP Maps 25, 26, and 27 displaying shaking amplification hazard of western Metro Vancouver, British Columbia, Canada, corresponding to long spectral periods (spectral acceleration of 1, 2, and 5 seconds) equivalent to a 2% probability of exceedance in 50 years hazard level or mean 2475-year return period.

本数据集包包含编号为25、26、27的MVSMMP地图，用于展示加拿大不列颠哥伦比亚省大温哥华西部地区的地震动放大危险性。该数据集对应长谱周期（long spectral periods）场景，其谱加速度（spectral acceleration）分别为1秒、2秒与5秒，对应的危险性水准等效于50年超越概率（probability of exceedance）2%的地震危险性水准，或平均2475年重现期（return period）的地震危险性水准。
