INVESTIGATION AND ANALYSIS OF MACROSCOPIC ANOMALIES BEFORE AND AFTER PISHAN MS5.1 EARTHQUAKE 0N JULY.2,2022

  • 摘要: 本文以地震宏观异常现象的历史发展过程为出发点,具体描述和田地区皮山县震中周围动物震前、震后异常变化现象和特征。阐述了新疆和田地区皮山 5.1级地震现场震中西南方向6~15 km村庄农户圈养的牛、羊等不同动物反常现象,并针对在地震前后动物发生异常变化的18个调查点、98次异常进行详细统计。其中,皮山县乔达乡8个调查点7种动物宏观异常显著,异常数量总计46次;昆泉镇10个调查点4种动物宏观异常显著,异常数量总计32次。经统计,临近地震发生前 24~36小时左右,狗、鸡、鸽、鸭反应异常显著,总宏观异常次数占比较高,动物主要表现为动物躁动不安、狂吠不止。由此分析得出:临震前,在不同时间段的11个调查点附近7种动物具有较明显的异常反应,时间尺度上来看,离震中越近的地方,动物异常越早,异常动物数量、种类越多;反之越少。宏观异常现象方面,具有向震中区域靠拢的趋势,空间分布较为集中。

     

    Abstract: Based on the development history of earthquake macroscopic anomalies, this paper briefly describes the characteristics of earthquake macroscopic anomalies, and describes the abnormal behavior of different animals, such as sheep, cattle, ducks, pigeons, pheasants and dogs, raised by rural farmers around the site of the Pishan Ms5.1 earthquake in Hotan, Xinjiang Uygur Autonomous Region, and makes statistics and analysis. It is believed that the macroscopic anomalies of the earthquake have certain characteristics of short-term and imminent anomalies in time, and are uneven in distribution, and are generally concentrated in villages relatively close to the epicenter.
