Tutorial 4 - Geophysics (Seismology): Ideas and basic concept

[yvonnefroehlich]

Within the pre-workshop we plan to have a tutorial covering topics regarding geophysics / seismology (see Tutorial 4 in the schedule table at https://hackmd.io/JtJP8TyNQBiEUNGHZwfhhg#Schedule). This issue should help to bundel ideas for topics and the basic structure before starting to work on a JN in PR to avoid double work 🙂. Feel free to edit this issue and add your own ideas 🚀.

Possible topics

• focal mechanisms (beach balls): Figure.meca
  -> https://www.pygmt.org/dev/gallery/seismology/meca.html
  -> WIP: Add tutorial showing how to plot focal mechanisms (beachballs) pygmt#2550
• geology (faults): Figure.plot (line fronts)
  -> https://www.pygmt.org/dev/gallery/lines/linefronts.html
• anisotropy (bars): Figure.plot (orientated bars), Figur.velo (so far not used by @yvonnefroehlich )
  -> https://www.pygmt.org/dev/gallery/seismology/velo_arrow_ellipse.html (actuall on velocity arrows)

I think "seismic anisotropy" might not be simple for non-seismologists.

I have some ideas:

1. profile, seismicity, and focal mechanisms (maybe Mw>6)
2. relative plate motion(velo) ?
3. lithosphere thickness (xyz2grd/grdimage/grdcontour) https://ds.iris.edu/ds/products/emc-cam2016/
4. geology(faults and volcanos)

I think it is better NOT to explain about focal mechanisms. It is a specific module just for that. For those who are not interested, it will not bring them anything. For those who are interested, I think they can learn it on their own. It is a simple module. I would mention that it exists.
