LIGO Main Page

[|Seismic Waves] - This site helps you know the differences between P waves and S waves. It also gives you more information on all the different waves.

For my earthquakes, I used the website http://quake.usgs.gov/recenteqs/Quakes/quakes0.htm which told me of earthquakes in California and Nevada. I'd plug in the time for an earthquake and find it in the LIGO data. I also used another website, after I found it on the first, because this site mainly contains UTC time. http://earthquake.usgs.gov/

[|Earthquake Presentation.ppt] - my powerpoint with my earthquakes

These three graphs, show that there was an earthquake between the time of 2:30-3:00 and there was also another one around 6:00. There shows a difference between seismic x and seismic y graphs. With the the seismic x it shows a higher intensity level with the first earthquake, but in the seismic y it shows a higher intensity level with the second earthquake. In the seismic z the first earthquake has the lowest intensity of the three and the second earthquake has the highest intensity of the three. Earthquake 1 Time: 2:14:52 Date: 9/30/07 Magnitude: 3.0 Latitude Degree: 32.689N Longitude Degree: 117.148W Depth (km): 10.4 Location: 3 km (2 mi) ENE of Coronado, CA

An earthquake takes 2km/sec. From Coronada, CA to Hanford, WA it is a total distance of 2057.911km. You would divide that by 2 to get 1028.96 seconds. Then divide it by 60 to get 17.15 minutes. It would take 17.15 minutes for the earthquake to reach Hanford, WA. The time the earthquake to travel from Coronada, CA to Hanford, WA was about 20 minutes.

Earthquake 2 Time: 6:04:51 Date: 9/30/07 Magnitude: 1.7 Latitude Degree: 37.861N Longitude Degree: 122.243W Depth (km): 9.8 Location: 3 km (2mi) ESE of Berkeley, CA

From these graphs, it states the possibility that there was an earthquake between the times of 13:30 to 13:50 (1:30-1:50). Also, there could have possibly been one around the time of 16:30 (4:30). These four different graphs are all for seismic x, but have a change in filter for each one. Earthquake (1) Time: 13:37:43 Date: 9/27/07 Magnitude: 1.7 Latitude Degree: 33.852N Longitude Degree: 117.485W Location: 8 km (5 mi) ESE of Corona, CA Depth (km): 0.0

Earthquake (2) Time: 16:21:14 Date: 9/27/07 Magnitude: 0.9 Latitude Degree: 33.480N Longitude Degree: 116.477W Depth (km): 15.2 Location: 20 km (12 mi) ESE of Anza, CA
