Earthquake off the Coast of Andaman and Nicobar Islands


The earthquake taking place a little after 8 o'clock is an earthquake off the coast of the Andaman and Nicobar Islands.

Here is the location of this earthquake: media type="googlemap" key="http://maps.google.com/maps?f=q&geocode=&hl=en&jsv=107&q=12.1550+92.4600&safe=active&ie=UTF8&s=AARTsJrnqDntujSsIyt6qHX_SqUQkcE9fg&ll=43.580391,167.34375&spn=143.80149,298.828125&z=1&iwloc=addr&output=embed" width="425" height="350"

The earthquake originally started at 7:39:30.51 and according to the graph the earthquake would have to reach LIGO at around 8:10. The earthquake wave would be a p-wave because the wave would be traveling mostly through water. A p-wave takes between 5-8km/s. The distance between the Islands to Washington is roughly about 12,575km.

(Note: I determined the distance of this earthquake by using the ruler tool in Google Maps. On Google Earth the total distance would be 12,779.82 km. Using this distance still gives you the time of about 35 minutes for the earthquake to travel to LIGO as shown below.)

Here are the details of the earthquake taking place in the Islands, once again taken from the [|Earthquake Catalog Search and Map].



Here is the math I did to figure out how long the wave takes to travel to Washington.

The wave takes about 35 minutes to reach Washington. Depending on the math and how many kilometers one might use per second, the wave would reach Washington around 8:15. Looking at the graph, you can see that the earthquake did hit LIGO around the time of 8:15. The earthquake matches the LIGO data! :]
