Ambient noise cross-correlation observations of fundamental and higher-mode Rayleigh wave propagation governed by basement resonance
[1] Measurement of basement seismic resonance frequencies can elucidate shallow velocity structure, an important factor in earthquake hazard estimation. Ambient noise cross correlation, which is well-suited to studying shallow earth structure, is commonly used to analyze fundamental-mode Rayleigh waves and, increasingly, Love waves. Here we show via multicomponent ambient noise cross correlatio...
متن کاملtrace reconstruction by parabolic radon transform
due to some difficulties during seismic data acquisition, like natural obstacles (high voltage electricity cable, bad coupling of geophones with the ground) some of the traces cannot be recorded. since bad traces make the final stack unclear, usually bad traces go mute while processing. the final image of the earth’s crust is highly dependent of the quality and resolution of acquired data and m...
متن کاملSurface Wave Tomography of China from Ambient Seismic Noise Correlation
We perform ambient noise tomography of China using the data from the China National Seismic Network and surrounding global and regional stations. For most of the station pairs, we retrieve good Rayleigh waveforms from ambient noise correlations using 18-months of continuous data at all distance ranges across the entire region (over 5000 km) and for periods from 70 s down to about 8 s. We obtain...
متن کاملRadon-Wigner transform for optical field analysis
The investigation of the local properties of an optical field requires its representation in phase space. Recently optical wavelet analysis has been used for the investigation of inhomogeneous fields [1, 2]. Mostly, one prefers to consider intensity distributions, which can easily be measured in optics. Unfortunately, scalograms (squared moduli of the wavelet transform) are not invertible in ge...
