The seismic zoning map was worked out separately by use of earthquake intensity and peak value of horizontal acceleration of bedrock.
区划图是分别用地震烈度和基岩水平加速度峰值来编制区划的。

Mercury observation technology is used to explore underlying faults in basins coordinating with seismogeology and intensityzoning.
本文主要根据测汞技术在震区配合地震地质、烈度区划等项工作，目的是探测盆地内的隐伏断层。

It is discovered that the Basic intensity offered by the Zoning Map is roughly equivalent to an average intensity level with exceeding probability of 0.14 in 50 years.
