Thanks Alan - I'll fetch it from work where we have a better Internet connection - it looks like a 8MB file for download !

We saw those aftershocks over here Friday - we were a bit nervous, but like you say, we can't tell if they were aftershocks or just a small swarm out in the desert.

The only unusual thing might be that there hadn't been any 'swarms' in that area for a while - There had been a Magnitude 5+ in that area within the last 6 months or so - I saw the swarms and figured they were aftershocks to that set of quakes we had out there. - So maybe those slightly larger quakes earlier this year were also 'foreshocks'
