A 300-500 meter array of 15-30 Texans will leapfrog along a 15-km E-W transect across the Reno metropolitan area. The arrays will record several 1-minute microtremor records at each layout. Records will be analyzed with a p-f transormation for Rayleigh dispersion curves. Dispersion curves will be modeled for Vs to 150 meter depths, and the scales of lateral variation in shallow shear velocity assessed.
