KH+Earthquake+02-02-2006




 * Earth Quake Information
 * The distance from Hanford, WA to the quake at latitude 35°38'27.60"N, longitude 139°48'43.26"E is aproximately 10, 326.76 km.
 * The traveled primarily over water there for the P Waves of the earthquake were recorded by LIGO, which travel around 5-8km/sec.
 * The quake was recorded to have started at 07:13:11.44 GMT with a magnitude of 5.60 by [|NCEDC].


 * Procedure
 * First I looked through data at [|NCEDC] and found a quake on 02/02/2006 with a magnitude of 5.60. Next I used the [|Bluestone] tool to look at the data for LIGO on 02/02/2006. The above graph is what I got and it looks like the large earth quake may of been identified around 07:35:00 GMT. Next I found the distance between LIGO and the earthquake using Google Earth. After I found the distance to be 10, 326.76 km I used the know speed of P Waves to be 8 km/sec and proceeded to use conversion factors to change the distance into minutes. 10, 326.76 km x 1 sec/8 km = 1290.845 sec, then 1290.845 sec x 1 min/60 sec = 21.514 min Using the information I have found, I know that the earthquake would arrive at aproximately 07:34:00 GMT.


 * Conclusion
 * Using the graph above, LIGO observed a large incident at 07:35:00 GMT which is close to 07:34:00 GMT. The margin of error makes this incident confirmed to be the earthquake that took place at 07:13:11.44 GMT.
