Late Quaternary Paleomagnetic Intensity Record in Taipei Basin, Taiwan

The Central Weather Bureau has implemented the Taiwan StrongMotion Instrumentation Program(TSMIP)to collect high-quality instrumentalrecordings of strong earthquake shaking.Deployment of theaccelerographs started in August 1992.By June 1997,629 stations hadbeen deployed.Each operating free-field station includes triaxial accelerometers,a digital recording sub-unit,a power supply and a timing system.Since the first installation in August 1992,this network has recorded 2482earthquakes.The local magnitudes of these earthquakes ranged from 1.7to 7.1 and thousands of high-quality digital accelerograms were collected.The quality of 16-bit data is shown to be much better than the conventionalstrong-motion data(either analog or 12-bit digital recordings).These newrecordings provide an excellent database for making various earthquakeengineering and seismological studies.
