AL's+Week+of+April+28

__4/28/08__ - Started my post-assessment for the LIGO interpretation assignment. I've created the page where my google map, assessment and arguments will be, and I've looked at the seismic graphs from bluestone to see what I have to do.

__4/29/08__ - Went to the lab at Notre Dame since it's Tuesday and I further discussed my new project on DNA necklacing which I will hope to continue over the summer but which I'm starting this week.

__4/30/08__ - I outlined my post-assessment and made my google map complete with the entry of the location of the earthquake according to the coordinates given. I also analyzed the y seismic graphs where I found the time at which I approximated that the earthquake started. Also found the distance from Hanford, Washington to the earthquake site from over the Pacific. According to the Z seismic graph, the detection time was 4:05 while on the y seismic graph it was 4:15. According to the bluestone program, the earthquake happened at 3:50.

__5/1/08__ - According to my hypothesis that the difference in detection times is due to different routes the earthquake waves took to reach Hanford, I measured, on Google maps, the distance over Eurasia and the Atlantic.

__5/2/08__ - Today I calculated the speeds based on the times and distances, so here are my reasonings that I have and posted on the post-assessment page.

__**Y Seismic Graph**__: From the graph, we can see where the detection begins at 4:15 while the earthquake happened at 3:50:40:80. The speed for the //**distance over the Pacific would be 7.27 km/sec**//, because 10,904.53/1500 sec (time between earthquake happening and detection) = 7.27. //**The speed over Eurasia and Atlantic would be 15,006.45 km/1500 sec = 10.0043 km/sec**//.


 * __Z Seismic Graph__**: In this graph, the earthquake is detected around 4:05 given from the same earthquake at 3:50:40:80. We see there is a 15 minute difference between the detection and the happening for the z-seismic graph. //**The speed of the quake over the Pacific would be 10,904.53/900 sec = 12.12 km/sec. The speed over Eurasia and the Atlantic would be 15,006.45 km/900 sec = 16.67 km/sec for the earthquake detection to happen over this route.**//
