Seismic Community Gathers for SITS

The 2013 Seismic Instrumentation Technology Symposium (SITS) was held in Albuquerque, NM on June 10th and 11th, 2013.  The well-attended symposium provided a splendid opportunity for members of the seismic community to exchange knowledge on instrumentation, as well as on novel approaches for improving the usefulness of data.

Here are some informal moments from the symposium, which was capped by a Tuesday afternoon tour of the Albuquerque Seismological Laboratory (ASL).  Copies of symposium presentations are posted for perusal at the conference agenda page.




Srikanth Saripalli (Arizona State, at left) talks shop with Allan Sauter (IRIS PASSCAL).





Albuquerque Seismic Laboratory Scientist-in-Charge Lind Gee visits with IRIS PASSCAL Program Manager James Gridley.




John Hole of Virginia Tech talks about IRIS's Large N initiative. He emphasized that, in regard to enhancement of tomographic data, geographical density of arrayed sensors (Large N) is critical to the avoidance of spatial aliasing.



Raffaella Montelli (Geophysics Program Director, National Science Foundation) and Bob Woodward (Director of Instrumentation Services, IRIS) get in some networking between presentations. Raffaella spoke on "NSF's Innovation Call: A Suite of Relatively Untapped Opportunities for GEO PIs."



Rob Woolley(Director of Program Support and Special Projects at IRIS) and David Simpson (President of IRIS) pose for a picture in the foyer.




Bob Woodward and Kent Anderson (GSN Program Manager for IRIS) compare notes after a presentation.




Conference organizer Andrew Frassetto did a splendid job of overseeing the symposium.

Sridhar Anandakrishnan (Penn State) talks to the audience about Active and Passive Source Glacial Seismology.




After the conference, Charles R. "Bob" Hutt (center, wearing hat) led a tour of the the Albuquerque Seismic Laboratory (ASL) facility, located south of Kirtland Airforce Base, in Isleta Pueblo. Hutt was formerly Scientist-in-Charge at ASL for 17 years, and currently serves as a Senior Scientist at the lab.

Bob Hutt demonstrates one of the many historical artifacts and museum pieces stored at ASL. This device, the "Falling Pin" seismometer, advised users that it "Provides Valuable Evidence in Court Cases."



This GPS station at ASL is anchored to bedrock several meters below the surface.  It is part of the Plate Boundary Observatory (PBO) network.




During the ASL tour, Albuquerque was experiencing a 100oF+ heat wave. That made this shady tree an attractive spot for resting between tour stops.




IRIS/PASSCAL summer intern Kasey Aderhold is shown holding an original ASL measurement of the huge 1964 Anchorage, Alaska earthquake.

The ANMO station of the Global Seismographic Network (GSN) was one of the stops on the ASL tour.  This station turns out to have one of the lowest noise floors of the GSN and other networks, and was key in defining the Peterson New Low Noise Model.

The symposium and tour provided many opportunities for the exchange of ideas and enthusiasm.  The next symposium is expected to be held in the summer of 2015.
