(a) Spectrogram for waveforms from all stations in the network. The spectrogram amplitudes have been converted to decibels. (b) Power spectral density of waveforms from all the stations. Grey curves indicate the global New High Noise Model (NHNM) and New Low Noise Models (NLNM)59. (c) Heat map of all the Rayleigh wave dispersion curves using ZZ cross-correlations. (d) Heatmap of all the Love wave dispersion curves using TT cross-correlations. The plots in this figure were generated using Python-v3.8.18 scripts with Obspy-v1.4.060 and Matplotlib-v3.7.361, and combined using Inkscape-v1.2.212, please see Data Availability section for more details.
