甘肃地区“十五”数字化水温观测及其地震前兆监测效能评估
|
摘要
对甘肃地区已建成的"十五"数字化水温观测点的年、月、日动态特征以及主要影响数字化学温资料的干扰因素进行了分析,结果发现,多数井点的资料比较连续可靠,多数井水温观测年动态正常稳定。数字化水温观测中目前较为突出的问题是,个别井点水温动态中存在较大幅度的脉冲、突变,个别井点还有断记。根据以往的震例总结,多数井点有可能识别出破年变为标志的中期前兆异常,月动态规律清楚的井点,有可能在短期前兆监测中发挥效能。部分井点有可能在阶变和脉冲为特征的短临异常识别中发挥作用。并提出了进一步发挥井水温度观测监测效能的若干建议。
This paper analyzed the digital observation data of water temperature from "The Tenth-Five-Year" stations,including the yearly,monthly and daily dyn amic characteristics of the digital water temperature and some main influence fa ctors to water temperature in the digital observation.The results showed that t he data from most well points were reliable,and annual variation of digital wat er temperature observation were regular and stable.Currently,the main problem in digital water temperature observation was that there was a big pulse-amplitud e,abrupt shifts and interrupt logging in dividual point.According to earthquak e cases before,we can distinguish the mid-term precursor of earthquake in most well points with the symbol of broken annual variation and the short-term precur sor of earthquake in some well points with clear monthly dynamic feature.Some w ell points with step variation and pulse may act on identification of short-impe nding.The paper also gave some suggestions on well water temperature monitoring in order to exert efficiency more in this paper.
