KH+Earthquake+Identification+11-15-06




 * Earth Quake Information
 * The distance from Hanford, WA to the quake at latitude 46°35'31.20"N, longitude 153°15'57.60"E is aproximately 3,625 km.
 * The traveled primarily over water there for the P Waves of the earthquake were recorded by LIGO, which travel around 5km/sec.
 * The quake was recorded to have started at 11:14:13.57 GMT with a magnitude of 8.30 by [|NCEDC].


 * Procedure
 * First I looked through data at [|NCEDC] and found a quake on 11/15/2006 with a magnitude of 8.30. Next I used the [|Bluestone] tool to look at the data for LIGO on 11/15/2006. The above graph is what I got and it looks like the large earth quake may of been identified around 11:35:00 GMT. Next I found the distance between LIGO and the earthquake using Google Earth. After I found the distance to be 3,625 km I used the know speed of P Waves to be 5 km/sec and proceeded to use conversion factors to change the distance into minutes. 3,625 km x 1 sec/5 km = 725 sec 725 sec x 1 min/60 sec = 12.083 min Using the information I have found, I know that the earthquake would arrive at aproximately 11:26:00 GMT.


 * Conclusion
 * Using the graph above, LIGO observed a large incident at 11:30:00 GMT which is close to 11:26:00 GMT. The margin of error makes this incident confirmed to be the earthquake that took place at 11:14:13.57 GMT.
