Auditory sonification for ELF band signal of seismic electromagnetic radiation

A signal sonification method appropriate for detecting electromagnetic radiation due to the earthquake activities is developed. The radiation is usually accompanied by a background noise that is mainly caused by atmospheric discharges in the tropical regions. Data representing the seismic radiation is presented as sound via the concept of sonification. This is useful to immediately find out anomalous seismic radiation, which are often followed by a disastrous earthquake. from massive data collected from over forty observation stations. It is illustrated that the auditory display is north for the future earthquake prediction system
