利用美国国家和海洋大气管理局(NOAA)的大气温度数据,分析陆地地震和海洋地震震前震中上空的大气温度变化,研究其作为地震短临前兆的可能性.地震样本包括2014年2月12日于田Ms7.3地震、2008年5月12日汶川Ms8.0地震、2011年3月11日日本Ms9.0地震、2014年4月1日智利Ms8.1海洋地震、2013年3月27日台湾南投县Ms6.1地震和2014年5月30日云南盈江Ms6.1地震.结果表明:(1)震前,震中位置300~1 000hPa大气温度有较为一致的变化趋势;(2)200hPa与400hPa处(根据不同地点可选择其他,诸如350hPa、300hPa等高度数据)温度折线图在震前趋近或者相交,出现类似蝴蝶翅膀的“蝴蝶形”特殊曲线形状;(3)200hPa与400hPa温度差等值线图在(震前数月、数周或数天不等)震中附近区域的数值减小,温度差等值线图的塌陷最低点对应震中位置.以上规律有望应用于地震短临预测的时间与震中的确定.
Based on the atmospheric temperature data of the NOAA, the atmospheric temperature changes over the epicenter before and after the epicenter of the earthquakes and oceanic earthquakes are analyzed to investigate their potential as precursors to earthquakes, including 12 February 2014 Earthquake in Rizhao Day Ms7.0, May 12, 2008 Wenchuan Ms8.0 Earthquake in March 11, 2011 in Japan Ms9.0 Earthquake in April 1, 2014 Chile Ms8.1 Oceanquake in March 2013, March 27 Taiwan Nantou County Ms6.1 earthquake and Yunnan Yingjiang Ms6.1 earthquake on May 30, 2014. The results show that: (1) there is a consistent trend of atmospheric temperature between 300-1000 hPa before and after the epicenter; (2) 200hPa and 400hPa (according to different locations can choose other, such as 350hPa, 300hPa and other height data) temperature line diagram approaching or intersecting before the earthquake, similar to the “butterfly” butterfly wings "special curve shape; (3) 200hPa And 400hPa temperature difference contour map in the epicenter (ranging from several months before the earthquake, a few weeks or days) the value of the region decreases, the temperature difference contours of the collapse of the lowest point corresponding to the epicenter location.The above law is expected to be applied to Determination of the time and epicenter of the short-term earthquake prediction.
