Easy for YOU to say!

As you probably know, finding crossings is not that easy. Each ring is 360 pairs of points and there are 18 per quake. To outline the area you need to look at pairs of rings crossing pairs of other rings to somehow get the area corners.

You can see them easier than that!

It's easy for us to see a crossing, not easy for the program.

Michael wants seismicity, that's more clutter and confusion.
