Abstract

This paper used two-dimensional Principal Component Analysis (2DPCA) to determine total electron content (TEC) respond in the ionosphere for the huge gas explosion in Kaohsiung, Taiwan at 15: 59 (UT) on 31 July 2014. Results have shown that at a TEC anomaly over Kaohsiung and Taiwan from 16:00 to 16:05 (UTC) with the duration time of 5 minutes. Potential causes of the results were discussed with emphasis given to acoustic shock waves with the speed of 2500m/s and caused a TEC anomaly. Supposedly, it is possible to predict this explosion time due to the gas release just short time before this explosion if such explosion is very huge to reduce the number of dead people.
