KH+LIGO+Post+Assignment


 * 1.** The distance from the quake's epicenter to LIGO is 10,940.03 km.


 * 2.** The sesmic waves have to go through water which means that the sesmic waves have to be P Waves. P Waves travel at 5-8 km/sec.

The distance between LIGO and the quake is 10,940.03 km. The first plot shows a distrurance 15 mins after the quake. The second plot shows a disturbance 10 mins after the quake.

So we use conversion factors to get the speed.

First Plot

15 mins x 60 sec/1min = 900 sec 10,940.03 km / 900 sec is appoximately 12 km/sec.

10 mins x 60 sec/1 min = 600 sec 10,940.03 km / 600 sec is approximately 18 km/sec.


 * 3.** Since my estimated speed wavesare way off from the actual speed of P waves (5-8 km) I assume that what LIGO detected was not the specified earthquake. I hypothesis that the LIGO detected another large energy disturbance such as a different earthquake closer to LIGO. Since it would of took the P Waves 12-18 km/sec to reach LIGO by 4:00-4:05 GMT these plots are not the specified quake.
