甘肃省古浪县1927年5月23日Ms8.0地震滑坡数据分布图

1927年5月23日古浪M8.0地震触发了大量滑坡。全面客观地获取地震滑坡发生全景，对于理解地震滑坡宏观机制、发育强度、分布样式与规律，灾区恢复重建与滑坡防灾减灾具有重要意义。利用天、空、地相结合的手段，获取本次地震触发滑坡全景。   数据采用WGS-84地...

On May 23, 1927, the M8.0 earthquake in Gulang triggered numerous landslides. Comprehensively and objectively obtaining the full panorama of this earthquake-triggered landslide event is of critical significance for understanding the macroscopic mechanisms, development intensity, distribution patterns and regularity of earthquake-induced landslides, as well as for post-disaster recovery and reconstruction and landslide disaster prevention and mitigation in the affected region. By integrating space-based, air-based and ground-based observation means, the full panorama of landslides triggered by this earthquake was acquired. The data adopts the WGS-84 geodetic coordinate system...
