This is the sort of picture that you find to learn about seismograms that gives you the basics but doesn't really help much when you look at the real ones:

Thanks for posting that video! I had no idea that tidal stress influences earthquakes.

Ah, so you really wanna go down the rabbit hole. I'll see if I can find a seismology 101-type text that's low on the crazy math...but honestly, seismology isn't the most complicated thing the world. When you start getting into the math to describe how to model guided waves or the wave equation or using structure tensors or other assorted minutia it gets wild, but that's true of most science disciplines. On its face, its simple stuff. There are other geophysical techniques like EM, GPR, remote sensing and gravity that are equally fascinating.

This is a decent 101 lecture series. I skimmed through the first two videos and it covers a lot of stuff:

Oh, and this video is much better if you want to focus on earthquake waveforms:

That NBC guy needs to lay off the zoom.

It doesn't want to embed, but this is some awesome video.
