Bringing New Tools and Techniques to Bear on Earthquake Hazard Analysis and Mitigation

As part of Advanced Studies Institute, 30 students from the U.S. and the Americas will acquire examples of data that can be used in site characterization for earthquake hazard analysis. Data will be collected at a few, geologically diverse sites within the city of Santo Domingo. Broadband data collected with IRIS portable instruments will be analyzed by the students using Horizontal to Vertical Spectral Ratio (HVSR) and Spatially Averaged Coherency (SPAC) methods. The students will analyze short period data collected with other instruments using Multi-channel Spectral Analysis of Surface Waves (MASW) and Refraction Microtremor (ReMi) methods.

作为高级研究学院（Advanced Studies Institute）相关项目的组成部分，来自美国及美洲地区的30名学员将获取可用于地震危险性分析场地特征表征的数据样本。相关数据将在圣多明各市内数个地质多样性丰富的场地采集。学员将使用IRIS便携仪器采集的宽带数据，通过水平向-竖向谱比（Horizontal to Vertical Spectral Ratio，HVSR）与空间平均相干性（Spatially Averaged Coherency，SPAC）方法开展分析。此外，学员还将针对其他仪器采集的短周期数据，采用多道面波分析（Multi-channel Spectral Analysis of Surface Waves，MASW）与微动折射法（Refraction Microtremor，ReMi）进行相关分析。
