作为地震短期预报系统中的环节之一,在阿拉木图周围地区建立了由一批生物实验站和生物观测点组成的生物观测网。注意力主要集中在对蛇、家鼠、鸽子、鹦鹉、鱼、晰蜴、蜘蛛等动物习性的观测研究上。结果发现,这些动物对10≤K≤13.5的地震有反应,对1992年8月19日苏萨梅尔7.4级地震的异常反应距离可达345km。对90年代4次强震前的资料研究表明,动物行为异常时间和异常量级随震级增大而增大。M≥6级地震前生物前兆的时空分布模型表明,强震前生物前兆出现的时间从1.5个月到几分钟,可分为3个阶段;距离从300km到10km,也分为3个阶段;动物异常行为从I型(烦躁、抑郁或侵犯型)变为Ⅱ型(逃避型)。文中还指出,要注意区分动物季节因素和气象变化有关的行为,地震生物学应与地球物理、形变、地区水地球化学等资料综合研究,将其用于地震的短期预报。
As one of the links in short-term earthquakes prediction system, a biological observation network composed of a group of biological experiment stations and biological observation points was established around Almaty. Attention is mainly focused on the observational studies of the habits of animals such as snakes, house mice, pigeons, parrots, fish, beaks, and spiders. As a result, they found that these animals responded to earthquakes of 10 ≤ K ≤ 13.5, and the anomalous reaction distance to the MS 7.4 Ms 7.0 earthquake on July 19, 1992, reached 345 km. Data from 4 pre-strong earthquakes in the 1990s showed that time and magnitude of anomalous animal behavior increased with magnitude. The temporal-spatial distribution model of biological precursors before M≥6 earthquakes shows that the biological precursors before strong earthquakes occur from 1.5 months to several minutes and can be divided into three stages; the distances from 300 km to 10 km are also divided into three Stage; animal anomalies changed from type I (irritability, depression or aggressive type) to type II (escape type). The article also pointed out that we should pay attention to distinguish animal seasonal factors and meteorological changes in behavior, seismic biology and geophysics, deformation, regional water geochemistry and other data comprehensive study, it will be used for short-term earthquake prediction.
