Earthquake off the Coast of Indonesia
The earthquake taking place at about 4 o'clock is an earthquake off of the far southwest coast of Indonesia.

Here is the location of this earthquake: media type="googlemap" key="http://maps.google.com/maps?f=q&geocode=&hl=en&jsv=107&q=-5.3700+130.4770&safe=active&ie=UTF8&s=AARTsJoB-ypMhJr2wO0ssbKc5Rcq2foG_A&ll=46.073231,164.53125&spn=142.311988,298.828125&z=1&output=embed" width="425" height="350"

The earthquake would be traveling through water, meaning the waves will be p-waves. P-waves travel about 5-8 km/s. The wave traveled for about 12,000km before it reached LIGO in Washington.

(Note: I determined my distant roughly for this earthquake from Google Maps. The actual distant is 11,977.02 going from Google Earth. The change in the distance does not change the actual time by much. It is still roughly 33 minutes as seen below.)

Here is the details of the earthquake taken from the [|Earthquake Catalog Search and Map].



Here is the math I did to determine the distance and how long it took to reach LIGO. (Note: the 6 in the equation is 6km/s for the speed of the p-wave) From the math we can conclude it would take about 33 min for the earthquake to reach LIGO depending on how fast the speed of the wave would travel. The earthquake started at 03:28:15.53 off the coast of Indonesia. If we added 33 minutes it would be 03:58:15.53. This would be roughly the time, because the p-wave could be traveling between 5-8km/s and I only determined for 6km/s. In looking at the graph, you can see that the earthquake was registered a little before 4 o'clock. The earthquake matches!
