3) plates.ps

B/W map of plate boundaries (lines) and volcanoes that have
been active in the Quaternary

The above reference to Mueller et al. would be appropriate.

This map needs a lot of work:
- add the hatchures to the subduction boundaries
- add some plate boundaries that are missing
- add names of plates and important plate boundaries.
A good example to follow is figure 2.2 of Fowler's book.
