Waveforms
We've selected the two events we used for investigating velocity models for waveform comparisons. Those events are:
- A M8.15 northern SAF event (source 39, rupture 5, rupture variation 311, hypocenter just offshore about 60 km south of Eureka)
- A M7.75 southern SAF event (source 59, rupture 0, rupture variation 0, hypocenter near Bombay Beach)
