California Earthquakes, Rockfalls, and Lichens

这项研究遵循了新西兰正在进行的工作， 地衣的生长速度要准确地校准使用 历史同震落石 这是一个很好的方式， 了解地衣生长因子和史前地震。 这项技术在地震多发的加州的应用 这些地区将在不同的地理区域测试这项技术， 地震设置，并为研究添加额外的工具， 地震风险评估。 这项研究是 国家地震减灾计划。

This research follows ongoing work in New Zealand that shows growth rates of lichen to be calibrated accurately by using historical coseismic rockfalls. This is an excellent way to learn about lichen growth factors and prehistorical earthquakes. Application of this technique to earthquake-prone California areas will test the technique in a different geographical and seismic setting and add an additional tool to the study and estimation of earthquake risk. This research is a component of the National Earthquake Hazard Reduction Program.
