Look what I can Do

All of my earthquake locations

This is my GMT creation for today. It depicts all of the events I've spent the last 2.5 weeks locating. Because It's such a small area, there are no degree scales.it's between 19 and 20 lat, and -102 and -104 long.

Close up of cluster

Creation number two. Look at the gradient, as it goes from really shallow quakes to deeper ones. I don't know what that means yet...

 

The entire area, with stations

This is a station map, with my events on there. See how there aren't that many near my site

 

I don't think this is my image, at least not by my standards, as it doesn't really explain what's going on. Hopefully in the next couple of weeks things will work out.

Those look darn cool! I

Those look darn cool! I think the -B tag will let you put markes smaller than normal on your figures -B15m will do it every 15 minutes, for instance(pretty sure about that, I was messing around with it the other day). Still, gotta admit that the grayscale color maps look really slick with your depth colors, nice!

Those look great,

Those look great, Tiffany!!!!  Well Done!!  I would suggest, though, that you do put markers on the first two.  You can use markers smaller than degrees to show location

Thanks for posting these

Thanks for posting these slick figures! I find the middle one quite interesting. It appears that you are resolving southwesterly migration of the earthquake foci as they shallow. I have seen this inclined zone of seismicity in a paper by Brian Wernicke looking at dike injection near Lake Tahoe. The idea of that paper was that magma moves most easily along the plane of least principal stress. I don't know the particulars of your field area, or purport to call myself a volcano seismologist, but it might be worth pondering.

My other question relates to the station coverage map. There isn't great coverage to the SE. Do you think that may perturb your quake locations? It's nothing to fret over, no one has the "perfect" dataset, but how data distribution effects results is an important consideration, and something reviewers always want to know when they comment on papers!

Overall, nice initial results!

Yeah, we discussed the lack

Yeah, we discussed the lack of stations in that area. After I made these figures, we used hypoDD to diminish uncertainty in path length from the events. The result fo this was a smaller cluster with not as big a range in depths. I made some cross sections, and it appears there are two clusters within that new set, at two distinctly different depths. I'm still working on that.
