AP's+Earthquake+2

AP's Earthquakes Tabular Data First I entered my first day into the Bluestone analysis tool, Jan 8th, 2005. I noticed the large spike at about 6:00 GMT time. I then looked at my second week of data from LIGO and found that all of the earthquake readings in the morning and most of the day are in the 4.0 to 4.9 range. At 5:31 GMT an earthquake with a magnitude of 5.1 occurs which I believe is the one depicted on the graph.

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 a P wave to travel in one sec which is 5-8 km/sec. Doing this I found out that it took about 30 minutes to reach Hanford.

12,944.20 km / 7 km/sec = 1,849.17 km/sec 1,849.17 sec / 60 sec = 30.82 min.

Looking at the LIGO data, the spike occurs 6:00 GMT. It took about 30 minutes to reach Hanford so it should have reached Hanford at about 6:00 as the data shows.

With this evidence, I think that the same earthquake NCEDC recorded is the earthquake that LIGO recorded at 6:00.
