Аннотация: Air temperature variation over the epicenter before terrestrial and marine earthquakes is analyzed and its possibility being applied in short-term and impending earthquake prediction is examined. The data obtained from the National Oceanic and Atmospheric Administration (NOAA) in different height scales with hPa unit are analyzed. Показать полностьюEarthquake samples include the earthquakes in Yutian (Ms7.3, February 12th, 2014), Wenchuan (Ms 8.0, May 12th, 2008), Japan (Ms9.0, March 11th, 2011), Chile marine earthquake (Ms 8.0, April 1st, 2014), (Nantou Ms 6.1, March 27th, 2013), and Yingjiang (Ms 6.1, May 30th, 2014). The results show: (1) atmospheric temperature has more consistent trends at 300-1 000 hPa in the epicenter before earthquake; (2) the line charts of 200 hPa and 400 hPa temperature exhibit a graph with approaching and intersection (we can choose other height data such as 350 hPa, 300 hPa, etc. according to various locations) approaching earthquake occurring time. This special curve shape is similar to butterfly wings and be called as “butterfly pattern”; (3) the values of the air temperature difference between 200 hPa and 400 hPa are reduced in contour map near the epicenter area (a few months, weeks or several days before the earthquake). The lowest point of collapse in the contour map of air temperature difference corresponds to epicenter. The regularity is expected to be applied to predict on time and epicenter in short-term and impending earthquake. ©, 2014, China University of Geosciences. All right reserved.
