Abstract
Analysis of seimsic background noise is found to provide interpretable data for geothermal exploration, if proper samplign and processing methods are used. Noise characteristics are seen to be stable over times of months, when smapled at quiet (early morning) times. Continued noise power anomalies can be due to think low relief surface material. Frequency was number (F-K) processing allows mapping of wave propagation direction and velocity, providing information on sturctural variations and/or local noise sources.
