Interests
My current projects are related to building a very large collection of seismic data, collaborating with others interested in using that data in their research, and creating unique data products from the data collection. The data collection is called ADEPT and currently contains more than 52 million 2-hour seismic data files from 25 data centers worldwide. Data are available for all events greater than M5.9 since 1/1/1995. Using the data from ADEPT, I have created a set of 2-hour three component record sections and maps for every M5.9 or larger earthquake since 1/1/1995. These are freely available on the SWAT web site. I am currently working on a system to measure travel times and arrival pulse spreading for each event and station in the ADEPT data set. This should be available soon. Jonathan Wolf has used the ADEPT dataset to create a large collection of shear-wave splitting measurements, available HERE. I have also created a web site using the broadband seismometer installed in the basement of the Bateman Physical Sciences Center on the ASU campus. This automated system (HERE) determines whether earthquakes are sufficiently above the seismic noise level (which is high on campus due to being in a major metropolitan area), plots those earthquakes determined to be "good", and alerts users to newly plotted earthquakes via email. I also have a broadband seismometer installed near my home in southern New Mexico. A plot of the most recent 24 hours of activity can be viewed HERE. |
