Nope, I'm not a seismologist so any opinion I express is just an informed opinion, so you'll have to look that up yourself and form your own conclusions. I've been doing this shit for decades but nobody would call me an expert. Just an enthusiast. So anything I say someone will dispute. Better to read some articles and study some waveforms yourself until you feel comfortable that there is a difference and you can tell the difference.
