The Idaho National Engineering and Environmental Laboratory (INEEL) operates 26 seismic stations remotely located in southeastern Idaho and 25 strong-motion accelerographs located at critical facilities at the INEEL site. The INEEL seismic network has recently upgraded standard analog instrumentation at all of its seismic stations to digital recording systems. Seismic data are transmitted to a central recording laboratory in Idaho Falls, Idaho using 900 MHz wireless modems. INEEL has also chosen digital recording systems to replace the 25 analog film-recording strong-motion accelerographs. INEEL chose to field-test the Applied MEMS, Inc. model SF1500A tri-axial accelerometer1 with the digital recording system...
