Wells, Nevada Aftershock Recording

We propose to record aftershocks of the 2/21/2008 M6.0 normal-faulting earthquake that occurred near Wells, Nevada. Wells is about 280 miles east of Reno, and not far from the Utah border. The town was damaged, locally severely. This earthquake is of scientific interest for several reasons,it occurred in the middle of the active TA deployment,well-recorded normal faulting earthquakes are rare even in the global data set,regressions for attenuation, peak acceleration, and peak velocity are poorly known in the Basin and Range,it occurred in a region of very slow secular extension.

本研究拟记录2008年2月21日发生于美国内华达州韦尔斯（Wells）附近的M6.0正断层型地震的余震。韦尔斯地处里诺（Reno）以东约280英里，距离犹他州（Utah）边境不远。该城镇在此次地震中遭受破坏，局部区域损毁严重。此次地震具备多项科学研究价值，具体原因如下：其一，其发生于活跃TA台阵布设的核心区域；其二，即便在全球地震数据集当中，记录完整的正断层型地震亦较为罕见；其三，在盆地与山脉省（Basin and Range）区域内，地震衰减、峰值加速度与峰值速度的回归分析模型尚缺乏充分研究；其四，该地震发生在长期构造伸展速率极慢的区域。
