中文摘要 | 臺灣地區地震活動頻繁,嘉南地區更是有多次災害性地震發生,而近來更預測嘉 南地區即將發生強烈地震其言之鑿鑿而造成大眾恐慌。本研究乃是利用由國立中正大學地震 研究所,中央氣象局地震測報中心與中央研究院地球科學研究所合作建立之嘉南地區地震監 測網在1994年6月至1995年2月間所得之地震資料,在地震震央分佈、每月地震個數及每季地 震規模型態等三方面進行統計分析,以期探討嘉南地區近期之地震活動。其結果顯示在地震 震央分佈方面未有明顯持續聚集之群震產生,每月地震個數亦無顯著大量增加或減少的情況 ,而各種規模之地震所佔比例也沒有明顯消長情形。故綜合以上三項而言,嘉南地區近期地 震活動並未有異常現象。 |
英文摘要 | Taiwan is located in the area where is risk of earthquake. In the past, Chia-Nan area, south-western part of Taiwan, experienced many strong earthquakes, resulting in a large number of lives and properties loss. Recently, the public panic has seemed to be got into due to the prediction that there will be strong earthquake happened in the Chia-Nan area. This study is to understand the recent earthquake activity in the area. This research mainly utilizes the seismic data form June 1994 to February 1995 of Chia-Nan area earthquake observation network, which was set up by Chung-Cheng University, supported by Central Weather Bureau Seismic Network (CWBSN) and the Institute of Earth Science, Sinica. The data were then interpreted in terms of distribution of epicenters, number of events per month and patterns of magnitude in every three months. The results show that there was no obviously continuing earthquake swarm happened in Chia-Nan area. There was no significant variation in the number of events per month. The magnitude of earthquakes remains in normal situation. Therefore, concluding all the above, there is no abnormal phenomenon of recent earthquake activity in Chia-Nan Area. |
