- Abstract:
- We calculated the energy ratio of low frequency to high frequency of ray based on the relation between ray energy and wavelet packet transform coefficients.The result shows that while decomposition scale is 1,the value 10/Ω11)is generally less than 3.0 for earthquakes,but more than 3.0 for explosions.It is suggested that wavelet transform theory can be applied to the discrimination of the earthquakes and explosions in Ningxia and neighboring areas.
