Hello Richard;

Thank you so much.
I tried to retrieve this info from the USGS but for some
reason was unable to find it.

According to this info I have read my gram all wrong.
I did not get my P and S phases right.

It was more like some kind of bizaaro Pn to Pg wave.

According to this new info the event might have been a blast
in the Ml range of 2.1 just downstream of Roosevelt
Dam. It seems very close to a roadway and this makes
me wonder if construction of some kind was going
on what used to be a dirt road.

If it was a real EQ it is the first of its kind that I have ever seen.
And being so close to the DAM is quite interesting.

Thank you for your reply.

When I re-read the seismic chart I get the same reading
which the USGS has posted.

This gram I will send to anyone interested.
Simply email me with a request and I will
send you the data to whatever degree you desire.
Like:
Image file or PSN file or RAW data as it was collected.

If my reading had been right it would have been a
bigger event by one magnitude except 80
miles away instead of 25 miles.

I guess I shall never learn to read these things right all the time.

Best regards,
geoff
