Trouble Matching Synthetics with Observed data #8

Open Rinku-274 opened 8 months ago

Rinku-274 commented 8 months ago

I want to make the green's functions for 1D local velocity model with these parameters: freqmin = 0.025 freqmax = 1.0 npts = int(2048) dt = 0.02 The synthetics have been generated. But it is difficult to match the waveforms. The output parameters looks like this.

Deviatoric Moment Tensor Inversion Depth = 5.0000 km Mw = -0.42 Percent DC/CLVD/ISO = 28/72/0 VR = 0.00%

Deviatoric Moment Tensor Inversion Depth = 15.0000 km Mw = -0.25 Percent DC/CLVD/ISO = 79/21/0 VR = 0.01%

Additionally, I have attached the waveform fits. Please inform me if any errors are present in my approach. bbwaves d15 0000 00

Looks like you cut off the data right before the earthquake signal (the black lines), try increasing the data length in the input parameter file first.
