Earthquake location

The little red circle is the P-wave for AYURT and it was very hard to find

This figure shows the move out of an earthquake across our array. "Move out" refers to the way an earthquake signal arrives at different times, so it looks like it moves across the screen. This earthquake hit the station called CROAD first, then BHIKE, and lastly the station by our camp called AYURT.

Using the good old pencil and paper method I approximated the location of the earthquake.
The pencil and paper method works as follows; first, I found the time between the P- and S-waves. Then, I got a distance from each station using a universal seismic wave travel time chart and drew a circle on a map centered at each site. The place where all the circles intersect is the approximated location of the earthquake. Then, I looked at the AEIC database and found the actual location of the earthquake and found out that my guess was awesome.
