The Global Seismology and Tectonics Group is located in a complex of offices and laboratories in the northwestern corner of the fifth floor of the Gould-Simpson Building on the University of Arizona campus in Tucson, Arizona. When we are not in the field, we are fortunate to reside in the Sonoran Desert, a region of fascinating geology and tectonics that includes a view through our windows of the Catalina Mountains, a famous “core-complex”. The Global Seismology and Tectonics Lab (GSAT) consists of a computer lab that is in the process of being upgraded from Sun Sparc workstations to 12 Imac and PowerMac workstations (networked together) and a Dell server with 14 SCSI disk drives in a RAID 5 configuration that will provide approximately 3.6 terabytes of disk storage for seismic data. The GSAT lab also operates (jointly with the USGS and Incorporated Research Institute for Seismology (IRIS)) the Global Seismic Network station TUC. The seismic data from the TUC stations goes to the Data Management Center at IRIS and is distributed to hundreds of users for Earth structure and earthquake hazard studies around the world.
