Abstract

Wavelet maxima method as a kind of data mining method has been applied to earthquake study, which gives us a direct way to identify singularities of different time and frequencies in long term of observations. This paper introduces how to identify electromagnetic anomalies using the wavelet maxima, i.e. the wavelet coefficients are calculated by using continuous wavelet transform and then calculate the maximum value of wavelet coefficients in each scale and identify the singularities associated with the earthquake.
