Socorro has decided to heat up to an unbearable 110 these past few days. Which has made doing anything outside (included my daily cycle to NM Tech) exhausting. I have worked up quite the tan though. It really does cool down in the evenings though, so I've been waking up around 5 every morning and going on runs with Brian every other day at 7. I did my first 10K this past Sunday, which was really exciting.
My project seems to be moving along - the tools I am using include SAC to view the data and make templates of known events to be used in a cross correlator as well as subspace detector, both of which scan the year's worth of Cascadia data for events. By using both, I am hoping to catch more events, given that they don't always coincide when determining when the data best matches the templates. The cross correlator and subspace detector are both written by Charlotte Rowe who is currently at Los Alamos National Labs. I've also used GMT to map the locations of known events, and I use Matlab to analyze the output of the cross correlator and subspace detector.
Currently I am focusing on a small cluster of events just off the coast of Oregon, looking at the 4 closest land stations and another 4 OBS stations with the intent to spot smaller events. The idea is to move up the coast, hopefully catching activity occurring where the subducting plate is still shallow. Templates have been made, with between 3-6 per station, and I've started running the cross correlator and subspace detector for the closest land station. It's a long run, on the scale of days - 364 days is a lot of data to run through, and the cross correlator has to do a separate run for each template. The subspace detector runs with all of the templates and tries to match the data stream using a combination of the templates, so it's quicker. I'll then visually inspect the seismograms, noting times of earthquakes that have identifiable P and S wave arrivals.
