Harper Lake Fault Slip Distribution, Central Mojave, CA

NCALM Project. PI: Jacob Selander, University of California, Davis. The original Seed project requested survey area of 40 km² was defined by two irregular polygons located along the Harper Lake Fault in the areas adjacent Gravel and Waterman Hills. Additional funding was secured to add two additional areas also located along the faults and between the original two polygons. The combined area of all the four polygons totaled 75.875 km². The final data collection has an area of 246 km² The Harper lake fault is aligned between the towns of Barstow and Ridgecrest, California. Two flights were required to collect the data. Both flights took place on Sunday June 17, 2012. It was collected on a Sunday because part of the survey area are underneath Restricted airspace controlled by the Edwards Air Force Base and access to it is preferably granted on Sundays. Also due to airspace restrictions the flying height above average ground was 900m rather than the preferred 600m. The plan consisted of 16 project lines running NW-SE along the fault center line.<p><br>Publications associated with this dataset can be found at <a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM's Data Tracking Center</a></p>

NCALM项目，项目负责人为加州大学戴维斯分校的Jacob Selander教授。原始Seed项目所要求的40 km²调查区域由两个不规则多边形界定，位于Harper湖断层附近的Gravel和Waterman Hills地区。通过额外资金的支持，成功添加了两个新的区域，这两个区域同样位于断层线上且介于原始两个多边形之间。四个多边形的总面积达到75.875 km²。最终的数据收集区域面积为246 km²。Harper湖断层位于加利福尼亚州Barstow和Ridgecrest两镇之间。收集数据共需两架次飞行，这两次飞行均于2012年6月17日星期日进行。选择在星期日进行数据收集的原因之一是因为部分调查区域位于由爱德华兹空军基地控制的限制空域之下，而对该空域的访问在星期日更为适宜。此外，由于空域限制，飞行高度被调整至平均地面上方900米，而非首选的600米。飞行计划包括16条项目航线，沿断层中心线从西北-东南方向延伸。<p><br>与该数据集相关的出版物可于<a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM数据追踪中心</a>找到。
