Design, Evaluation, and Construction of TEXESS and LUXESS, and Research in Mini-Array Technology and Use of Data from Single Stations and Sparse Networks
Abstract
Objectives are: (1) conduct research in seismic mini-array technology and use of data from single stations and sparse networks, and (2) design, evaluate and construct 2 mini-arrays - TEXESS (Texas Experimental Seismic System) in southwest Texas and LUXESS (Luxor Experimental Seismic System) which is northeast of Luxor, Egypt. TEXESS was installed by SMU personnel in August 1993. The array consists of 9 sensor sites, which include a central 3 component, short-period seismometer installation in a vault at the hub, and 8 vertical short-period seismometer installations in boreholes. In addition to the short- period instrumentation at the hub, a posthole KS 54000 long-period seismometer, owned by SMU, was installed in a shallow borehole. Advancements include: (1) placement of seismometers and electronics in boreholes to reduce pier and vault construction costs; (2) solar power at each site rather than a central-power source; (3) GPS receivers for time data at each seismometer site to replace central timing from the Hub; (4) radio links from seismometer sites to the Hub to replace cable links and associated construction costs; (5) modular equipment to facilitate the installation and maintenance of the array.
