Shear-wave velocity in the Seattle basin to 2 km depth characterized with the krSPAC microtremor array method: insights for urban basin-scale imaging - Data Release

The dataset for this investigation consists of microtremor array data collected at 11 sites in the Seattle basin, Washington State. Ten of the arrays consisted of seven Nanometrics Trillium Compact broadband sensors deployed in asymmetric nested triangles (sites ST01, BA02, SP04, LF05, UW06, SN07, RD08, EL09, CH10, and KG11) that recorded for up to six hours. The eleventh array, at site NW03, was supplemented with a smaller triangular array that recorded for about 1 hour before redeployment to a larger array. The inter-sensor distances varied from about 173 m to 2000 m. The data were recorded on Reftek RT-130 data loggers and converted to SAC binary format for archival. All three components were recorded from each sensor. Coordinates of each sensor location are provided in UTM zone 10N format, WGS84 datum. Field logs describing the sensor locations and instrumentation are also provided.

本研究使用的数据集为采集自华盛顿州西雅图盆地11个测点的微动台阵数据。其中10个台阵由7台Nanometrics Trillium Compact型宽带传感器（Nanometrics Trillium Compact）组成，采用非对称嵌套三角布设方式，测点编号为ST01、BA02、SP04、LF05、UW06、SN07、RD08、EL09、CH10及KG11，单台阵最长连续记录时长可达6小时。位于NW03测点的第十一个台阵，先期布设了小型三角台阵并记录约1小时，随后重新部署为大型台阵。传感器布设间距范围约为173米至2000米。数据通过Reftek RT-130数据记录仪采集，并转换为SAC二进制格式进行归档保存。每个传感器均采集三分量数据。各传感器的位置坐标采用UTM投影带10N、WGS84大地基准面格式提供。同时还附带了描述传感器布设位置与仪器配置情况的野外日志。
