Chris;

I'm using the NEIC topo map. Triangular symbols, 3 different sizes based on mag. Quakes before are white, after are yellow.

I can't change the size of the map.

Send me your address. Can't post here without Canie.

I'll separate before and after on different maps because they overlay one another too much.

There were 18 quakes of 7+ in 2001 and the time between them is frequently less than 10 days. I can delete one of them for the plot or I can plot both ring sets, but that can be confusing too.
