Signal processing and sonification of seismic electromagnetic radiation inthe ELF band

We have developed a signal processing method that is appropriate for detect ing electromagnetic radiation due to earthquake activities. The radiation i s usually accompanied by a background noise that is mainly caused by atmosp heric discharges ill the tropical regions. Data representing the seismic ra diation is presented as sound via the concept of sonification. This is usef ul for immediately finding out anomalous seismic radiations, which are ofte n followed by a disastrous earthquake. from the massive data collected from over forty observation stations. It is illustrated that tile auditory disp lay is valuable for future earthquake prediction systems.
