中央氣象局地震測報中心自1990年起，推動建立全省的強地動觀測計畫。預定設置1000部加速度型強震儀來收集強地動資料，以進行地震災害分析。到目前為止，已經有六百多部自由場的強震儀於全省監測地動情形。為維護儀器正常運作及資料蒐集方便，強地動觀測計畫將全省分成七個區域，分別由不同的大學與研究單位負責資料收集的工作。本所負責的中部地區（面積約150公里＊140公里）原包括147個強震站及12座結構物地震監測系統。自88年九月初起，另加入了17個IDS的儀器來觀測地震，計有龍潭的核研所；苗栗的建功、啟文國小；台中縣市的大勇、鎮平、外埔、神岡、白冷等國小；彰化縣市的湳雅、永靖、草湖、水尾、海埔、新寶與大同等國小；南投的北山、中寮國小；另有於89年新加入了台中梧棲氣象站與四個軍方營區以及南投的暨南國際大學，共計有153個觀測地震站，其後儀器更新，龍潭的核研所、苗栗的建功國小及啟文國小、台中縣的外埔國小皆更新為A900A的機種。強震站涵蓋桃園縣19站、新竹縣21站、苗栗縣24站、台中縣42站、彰化縣26站、及南投縣21站；而結構物系統則包括桃園縣3站、新竹縣5站、苗栗縣3站、及台中市1站。計畫主要的工作包含下列幾項：1）儀器維護 2）資料收集 3）背景雜訊分析 4）基本分析與資料整理。其目的是希望能夠收集高品質的強震資料，並使整個系統運作更為順利，以提高可信度。 The earthquake center of Central Weather Bureau has set up a program to promote the observation of earthquake strong motion over Taiwan island since 1992. The purpose is to establish a 1000-acceleragraph system to collect reliable strong motion data for earthquake hazard analysis. Among them, 600 instruments are deployed on the free field to monitor the ground motion. In order to maintain the instrument and to collect the data, the system has been divided into 7 areas, and distributed among the universities and research institutes to share the load of data acquisition. Our research group is in charge of area of Central Taiwan which has 153 stations and 12 building arrays including the counties of Taoyuan (19), Hsinchu (21), Miaoli (24), Taichung (42), Nantou (21), and Changhua (26), a total area of 150 km x 140 km. The task of this project includes 1) instrument maintenance, 2) data acquisition, 3) background noise analysis, and 4) documentation and basic signal analysis. All of these efforts will direct toward collecting high quality strong motion records and making the system operate smoothly and reliably. 研究期間：9101 ~ 9112
