Finally some results


So after spending this morning struggling with Unix, I finally got some results! Doug had to help me a bit but after the few speed bumps it was only a slightly bumpy road and I got my list of earthquakes, the data extracted, and run through the splitting program. I started with 13 earthquakes, 2 didn't extract and the N-S component wasn't working in 3 of the ones that did, so I am down to... 8 that I ran. One of them is all funky looking, so I have 7 to average.

A quick explanation of what I am doing:
I am looking at earthquakes that are M5.7 or greater that are 85-110 degrees away from my station, and looking at the S waves that traveled through the core as P waves and came back out as S waves. These waves have nice arrivals in this back azimuth range and show the alignment of the olivine (mostly) in the mantle, (Mantle lithosphere and asthenosphere) this gives you a flow direction in the mantle or at least a shearing direction. There is a station in my main set that is on a schist belt. The mantle has about 5% anisotropy and the schist has 30% so I am looking at this other station that is like 10 miles away and not on the schist to see if the schist actually shows up in the results.

so yeah
thats what I am doing
tomorrow I am going to look at what I got
right now I am just glad it all went through the program
and I have results TO look at!
