abigkahuna, you got me mixed up with someone else. I didn’t mention harmonic tremors. But you definately spark my interest: What are harmonic tremors and why are we in deep kimshi with them?
Because harmonic tremors ARE an indication of moving magma. Moving magma, especially under pressure, is not a good thing. Is the magma moving and filling cracks and casuing more cracks in its upward movment toward the surface? Or, is something less ominous happening? That’s why I wanted to know about where the supposed information regarding harmonic tremors. came from... From blogs, posts or opinions, or from something more credible like USGS? Make a bit of difference.
