技術說明:

海底地震儀(Ocean Bottom Seismograph,簡稱為 OBS)顧名思義就是架設在海底的地震觀測系統。為了因應海底特殊環境條件及其使用特性,海底地震儀在設計上有許多的考量與挑戰。需考量其電力來源、感應器水平架設以及水下環境考量等三大關鍵核心技術,故全世界僅有極少數國家有能力製造海底地震儀。
國家實驗研究院台灣海洋科技研究中心結合中央研究院地球科學研究所及中山大學海下科技研究所,自2008年起合作研發海底地震儀,至今已多次成功於外海長期佈放,且順利取得海底地震資訊,提高外海地震定位的準確度。
台灣自製之海底地震儀為品質穩定且優良的科研儀器,不但幫助國內學研界擺脫過去只能依賴進口昂貴的海底地震儀進行大地構造的相關研究,更重要的是後續地震儀的維護與整備自主性的建置,相信對於我國海底地震潛勢評估以及孕震構造關係等研究,都將有具體的效益與貢獻。

The Ocean bottom seismograph has designed to record earth motion under oceans, such as the seismic waves caused by tectonic activities. Ocean bottom seismograph deployments enable us to locate earthquakes and map the fault-geometry beneath the seafloor which are not well constrained by data recorded by land-based seismometers. However, there are lots of challenges (e.g. power consumption, size and weight, timing, unpredictable seabed environment) being faced to design a suitable Ocean bottom seismograph for the practical usage, so only a very small number of countries around the world are capable of manufacturing Ocean bottom seismograph.
Beginning from 2008, the ongoing Ocean bottom seismograph project has been leading by TORI, Academic Sinica, and National Sun Yat-sen University from designing, testing to success. Ocean bottom seismograph have been deployed and recovered in several research cruises and obtained the great results.
Taiwan-designed Ocean bottom seismograph units less expensive and weight (200 kilograms) than comparable foreign-made devices, not only long-term monitoring seismic activities but also anticipating to assess the potential hazards triggered by earthquakes and submarine volcanic activities. Auto sensor levelling mechanism in titanium housing for rugged environment. Compact size, light weight, ultra-low power consumption for year-long operation on seafloor up to 6000 m depth.
