Photogrammetric point cloud of La Rouviere fault, France

Point cloud extracted from 2007 stereo aerial imagery (IGN) covers the area of La Rouviere fault, near Montelimar, SE France. La Rouviere fault, an old tectonic feature with an approximate strike of NE-SW, was re-activated and ruptured during the November 11 2019 Mw 4.9 shallow earthquake. First results from SAR Interferometry and field surveys confirm surface ruptures that follow La Rouviere fault trace as mapped in BRGM geological maps.

自2007年立体航空影像（IGN）提取的点云覆盖了法国东南部蒙蒂利马尔附近的La Rouviere断层区域。La Rouviere断层，这是一处古老的构造特征，其走向大致为东北-西南，在2019年11月11日发生的Mw 4.9级浅源地震中重新激活并发生断裂。SAR干涉ometry和地面调查的初步结果表明，地表破裂沿La Rouviere断层线分布，与BRGM地质图所绘制的断层线一致。数据经过开源的MicMac摄影测量软件处理。
