Out of curiosity I decided to examine the inversion of the 20090423151408 earthquake in different frequency bands. I performed a search for the best solution in the depth range of 1 - 9 km. However I also considered different upper limits to the frequency range. I wish to know the highest usable frequency and I would also liek to know how well the model can predict peak motions at high frequencies, even though the waveform fit may not be as good.
Frequency Band | H(km) | STK | DIP | RAKE | Mw | FIT | Waveforms |
0.02-0.10 | 7.0 | 345 | 30 | -50 | 3.82 | 0.5566 | Predictions for 0.10 Hz |
0.02-0.20 | 6.0 | 330 | 30 | -60 | 3.82 | 0.4953 | Predictions for 0.20 Hz |
0.02-0.25 | 6.0 | 325 | 30 | -65 | 3.83 | 0.4585 | Predictions for 0.25 Hz |
0.02-0.30 | 6.0 | 330 | 30 | -65 | 3.83 | 0.4081 | Predictions for 0.30 Hz |
0.02-0.40 | 6.0 | 325 | 30 | -65 | 3.82 | 0.22867 | Predictions for 0.40 Hz |
0.02-0.50 | 5.0 | 105 | 60 | -65 | 3.79 | 0.1934 | Predictions for 0.50 Hz |
