乌恰7.4级地震前气象异常征象

1985年8月23日乌恰7.4级大震前某些气象要素有比较明显的异常变化,用乌恰及邻近地区的震前气象资料与历年资料进行对比分析,发现震中区震前的降水、气压、气温和地温的变化比邻近地区大,说明气象与地震之间确实存在某些内在的联系。

ANOMALOUS METEOROLOGICAL PHENOMENON AND FEATURE BEFORE THE EARTHQUAKE OF M=7.4 IN MUQIA

Anomalous change of some meteorological factors had taken place before the great earthquake of M_s=7.4 Occurred in Wuqia at 20 o''clock on August 23, 1985. Doing a statistical calculation of the meteorological data accumnlated over the years in Wugia and the neighbonring zones and comparing the obtained results, We discovered that the anomalies of the rainfall, and temperature, atmospheric pressure and temperature which had occurred before the earthquake in the central zone of earthquake were very apparent, and the earthquake epicentre is corresponding to the anomalous centre. This declares that some internal relations between meteorological phenomenons and earthquake exist really, so we think that the moterological factors can play a part in the earthquake forecast with a method of combining the meteorolocal factors with other measures.
