See the three questions below for the following quake:

 * =Date= || =Time= || =Lat= || =Lon= || =Depth= || =Mag= ||
 * 2005/10/08 || 03:50:40.80 || 34.5390 || 73.5880 || 26.00 || 7.60 ||

and the following plots derived from LIGO environmental sensing data:



 * 1. Use Google Maps (or Google Earth—your pick) to calculate the distance from the quake’s epicenter to LIGO.**


 * 2. Calculate the seismic wave speed twice, once for each of the LIGO plots shown.**


 * 3. Comment on any difference you see between the LIGO plots, and between the wave speed estimates obtained using each plot.**
