AP's Earthquakes Tabular Data

First I entered my first day into the Bluestone analysis tool, Jan 1 st, 2005. I noticed the large spike at about 7:00 GMT time. I then looked at my first week of data from LIGO and found that all of the earthquake readings in the morning and most of the day are around 5.0. At 6:25 there was a reading with a magnitude of 6.7 at Bluestone. I put the longitude and latitude coordinates in Google Earth and found the location of the proposed earthquake. I found the distance between the origin of the earthquake and Hanford. I took the distance in km and divided it by how long it takes an S wave to travel in one sec which is 3-5 km/sec. Doing this I found out that it took a little over 44 min to reach Hanford.

13,454.81 km / 5 km/sec = 2690.962 2690.962 sec / 60 sec = 44.85 min. Looking at the LIGO data, the spike occurs just after 7 GMT. If it took about 45 min to reach Hanford, it should have reached Hanford at about 7:10. I think that this is very solid proof that the data at LIGO is the same data from NCEDC.
