Abstract
At 22:55 on June 17, 2019, an earthquake of magnitude 6.0 occurred in Shuanghe Town, Changning County, Yibin City, Sichuan Province. In Shaanxi Province, the obvious earthquake sense appeared in some places which are 600 km to 800 km away from the epicenter. Based on the collection, collation and analysis of the data about Weihe Basin, Hanzhong Basin and Ankang Basin in Shaanxi Province, and the analysis of representative seismic network records and seismic wave propagation distance in each basin, the mechanism of the long-period disaster induced by the Changning Ms6.0 earthquake in Shaanxi Province is revealed. This study has a positive significance for the seismic fortification of long-period structures in this area, the scientific popularization of long-term ground motion effect, and the avoidance of earthquake panic.
Highlights
With the development of economy, there will be more and more long-period structures

Summary
With the development of economy, there will be more and more long-period structures (high-rise buildings, long-span bridges, large-scale liquid storage tanks, etc.). The Wenchuan earthquake on May 12, 2008 caused severe long-term earthquake damage in Weihe Basin, Hanzhong Basin and Ankang Basin in Shaanxi Province. Hanzhong Basin and Ankang Basin in Shaanxi Province, as well as the analysis of representative seismic network records and seismic wave propagation distance in each basin, the mechanism of long-period earthquake sense in these basins caused by the Sichuan Changning MS6.0 earthquake is revealed. The phenomenon that the earthquake with only magnitude 6.0 caused such a strong earthquake senses in Weihe Basin, Hanzhong Basin and Ankang Basin 600 km to 800 km away, is unprecedented.There is no doubt that long distance played an important role. The long-period earthquake senses of the high-rise buildings which are located in Weihe Basin, Hanzhong Basin and Ankang Basin, and are 600 km to 800 km away from the epicenter, are obviously felt in Shaanxi Province. The earthqiake senses of the high-rise buildings in Xi'an, which is far away from the epicenter, are strongly felt, while those in Hanzhong and Ankang near the epicenter are relatively weak
