Descr: Short description of project: 45 Texans in a 2-km array will collect 1-6 hours of microtremor data over a natural-gas reservoir in the Sacramento Valley of California. The array will cross producing and non-producing wells. Rayleigh-wave dispersions from the two wells will be examined for any evidence that surface-wave data can distinguish the two sites. This experiment will use only the PASSCAL equipment currently on loan to UNR.
