2017年5月11日新疆塔什库尔干M_S 5.5地震震害特征分析
|
摘要
2017年5月11日新疆塔什库尔干发生MS 5.5地震,该地震的发震构造为塔什库尔干断裂带,属于全新世发震构造,且为浅源型张性中强地震。此地区受欧亚板块和印度洋板块的挤压碰撞,构造活动剧烈。极震区位于地震断裂上方,灾害破坏较集中,地震对震中附近的库孜滚村造成了毁灭性破坏,与同级别地震相比,灾情较重。灾区位于帕米尔高原,自然条件恶劣,资源匮乏,经济落后,自建房屋质量差,抗震能力低,这也是本次地震震级不大、震害较重的重要原因。
On May 11, 2017, a MS 5.5 earthquake occurred in Taxkorgan of Xinjiang. The earthquake is in the Taxkorgan fault belts, which belongs to the Holocene seismogenic structure and is characterized by the shallow source and medium-strong earthquake. Thectonically, this region is effected by the Eurasian plate and the Indian plate together, so the regional tectonic activity is relatively strong. The most damaged zone is located above the earthquake fault, and the disaster damage is more concentrated, causing devastating damage to Kuzigun village near the epicenter. Compared to the earthquake with same scale, the degree of disaster is relatively high. The possible reasons for such "heavy damage with mediate scale of earthquake" are because of the poor natural conditions, lack of resources, economic backwardness, poor quality of self-built housing and low anti-seismic capacity.
