Does seismic amplitude have a constant regular attenuation in synthetic seismograms simulation with ideal conditions (on rock and 1-D velocity model)?

This is a question about earthquake amplitude attenuation. With your experience of observing earthquake waveforms or simulating ones, I hope you will give us some insight on that matter. I'm...

Is there an open code that can convert SAC data into SAF ?

Good morning, I tried converting seismic SAC data into SAF using Geopsy, but the results were not satisfactory. Is there any other way to do that conversion from SAC to SAF? Thank you

What is the tolerance misfit between seismic observed and synthetic data in the frequency domain?

Good morning, I'm trying to generate synthetic seismograms for an observed seismic event. I did compare the amplitude in the time domain, and applied the FFT for both observed and synthetic...

How to fix a proper velocity model for earthquake localisation using hypoinverse when several models give a good solution?

Good morning. I'm trying to fix a proper velocity model for waveform inversion. I thought that if I get a good "rms" with the localisation I can start the inversion with that velocity model. The...
