中文摘要 泥火山的形成一般是因為泥質沈積物由地下的高壓環境伴隨液體和氣體向地表冒出,而形成泥火山的必要條件除了受壓的泥質地層加上豐沛的液體及氣體可補充,還需有裂隙提供路徑讓深部地層的高壓流體向上竄升。現今對泥火山的研究相對其他地質構造的研究少很多,而現今大部分的研究方法,如外觀的行為分析、地化的成份分析、地物的地下探勘等,這些方法都並非採用連續觀測的方式,但本研究透過架設地震儀可長時間進行連續監測,定期將資料回收並且分析整理,在確定了泥火山的主要頻段後,使用濾波的處理將泥火山的訊號與其他訊號(如背景噪音、人為噪音、地震訊號等)區分開。本研究除了提供一種新的方法來研究泥火山,可補足前人對泥火山研究缺乏的自動化連續監測,因為可以準確紀錄泥火山活動時間及持續時間,還可用於配合其他觀測方法來對泥火山進行研究,這對泥火山的研究進展有極大幫助。
  本論文研究對象為旗山斷層帶上的新養女湖泥火山,本研究在對資料進行處理後分析,得知泥火山的活動訊號在15HZ以上開始出現,到本儀器最高可信頻率域皆有能量分佈,在時間序列顯示的形狀類似於火山地震中的螺絲釘型(Tornillos)活動,而活動的週期型態則有佔大部分時間的長時間微弱活動,這種噴發型式會在一天到一個禮拜不等的時間內,有規律的間歇式噴發,一個循環大約10到30分鐘,另一種噴發型式則是無間隔的連續噴發,這種狀態可長達兩個小時以上不中斷。觀察研究時間內發生的地震,發現少部分的地震對泥火山的噴發活動狀態造成改變。本研究配合其他方法的觀測資料做比較,其中包括了溫度與排氣量的測量,兩者與經分析處理後的地動訊號皆有一定的相關性。
英文摘要 In general, the formation of mud volcanoes is the deposition of muddy sediments from the underground high-pressure environment with liquids and gases to the surface. Compared with other geological structures, the study of mud volcanoes is much less. Most of today's research methods, such as the analysis of appearance, the analysis of components of geodesic, and the underground exploration of features, are not based on continuous observation. However, this study uses seismographs to record the ground motion signals of mud volcanic activity. This method can continuously monitor for a long time. In addition to providing a new method to complement the lack of automated continuous monitoring of mud volcanic activity in the past. Because it can accurately record the time and duration of mud volcanic activity, it also cooperates with other observation methods to study mud volcanoes. This is very helpful for the study of mud volcanoes.
The research location of this paper is New Yangnyn Lake Mud Volcano in Chishan fault zone. In this study, after analyzing the data, it is found that the activity signal of the mud volcano begins to appear above 15HZ, and there is energy distribution in the highest trusted frequency domain of the instrument. The form of eruption can be divided into two types, it is mainly a weak intermittent eruption in most the time. This is a regular intermittent eruption, a cycle of about 10 to 30 minutes. Another type of eruption is a continuous eruption without gaps, which can last up to two hours without interruption. After observing the earthquakes that occurred during the study period, we found that a small number of earthquakes affected the eruption activity of the mud volcano. This study is compared with the observation data of other methods, including the measurement of temperature and exhaust volume, both of which have certain correlation with the ground motion signals after analysis.
