2016年5月21日，澳大利亚中部彼得曼山脉沿线发生了里氏6.1级地震。由于受影响地区处于印澳板块的中心，地震活动性较低，可归类为罕见的板内地震。此外，彼得曼造山带剪切带的构造和运动学在很大程度上是未知的。我们使用Sentinel-1 c波段下降数据和ALOS-2 l波段上升数据来约束原因故障。我们的分析表明，地震沿该地区主要特征的未绘制的次级逆冲构造成核，即伍德洛夫逆冲构造。
On 21 May 2016, an Mwp 6.1 earthquake occurred along the Petermann Ranges in Central Australia. Such a seismic event can be classified as a rare intraplate earthquake because the affected area presents low seismicity, being at the center of the Indo-Australian plate. Also, the architecture and kinematics of shear zones in the Petermann Orogen are largely unknown. We used Sentinel-1 C-band descending data and ALOS-2 L-band ascending data to constrain the causative fault. Our analysis revealed that the earthquake nucleated along an unmapped secondary back-thrust of the main feature of the area, namely the Woodroffe thrust.
