Steve Roecker's Current Research Activities

	I'm in the process of trying to assemble information about my current research in a Web page format, but it's taking a bit of time and effort. Some of the pages are in good shape, others are dismal, some don't even exist yet. Please check in at a later date and more of the following items will lead you somewhere interesting.

Structure and evolution of the Tien Shan in central Asia.

The Tien Shan are one of the few examples of active intracontinental mountain building. My colleagues and I have been using seismological techniques to produce pictures of the structure of the crust and upper mantle beneath these mountains in order to understand their dynamics and something about how they evolved. The Tien Shan is a beautiful mountain range and a fascinating place to do field work. In the summer of 1995 I conducted a seismic reconnaissance field trip, and I have put all my notes and photos on line, so that you can take the TS95 virtual field trip to the Tien Shan. Arthur Chen and I went back to do another recon trip in October, 1996. You can find out what we did by embarking on the TS96 virtual field trip . I recently came back from another trip the Tien Shan in September and October of 1997, where I was part of a team that installed 6 seismic stations in the mountains. See the TS97 virtual field trip page , currently being constructed, for some pictures an discussion of this trip.

Here's one of my favorite pictures from the 1995 Tien Shan trip (click to get a full scale image):

Structure of the Upper Mantle investigated by reflected phases.

Studying effects of 3D Global Heterogeneity on Bounce Points of Reflected Phases.

Determining the motion of the Philippine Sea Plate through Geodetic Monitoring.

Investigating the Dynamics and Kinematics of the Adirondacks through a Combined GPS/Seismology project.

John Beavan and I put together a project to see if we can detect the uplift rate of the Adirondacks, and also try to understand what might be making them uplift. We remeasured some benchmarks installed in the Adirondacks more than 100 years ago by Verplank Colvin using modern GPS techniques. We also operated an array of four broad band seismic stations with the Adirondacks for a period of about one year.

Some pictures and descriptions of the field work are shown here

Looking for Structural Irregularities in the San Andreas Fault Zone.

RPI and UW Madison conducted active and passive seismic investigations of the San Andreas Fault zone in the Hollister, CA area in 1994 and 1995. You can view a few pictures from the field work here

Tomographic Imaging of the Yucca Mountain region.

Using P-SV converted phases to determine the structure of the crust beneath the Kola Peninsula.

Determining the depth of Mantle discontinuities beneath Central Asia.
