  • Although several real-time earthquake detection and recorder systems exist, few address the problem of continuously measuring the amplitude of seismic signals during volcano-crisis conditions, when individual events are difficult to recognize. We developed a real-time seismic-amplitude measurement system (RSAM) that uses an inexpensive eight-bit analog-to-digital converter controlled by a laptop computer to provide 1-minute-averaged, absolute-amplitude information for eight seismic stations… CONTINUE READING
