1. A method for seismic event mapping, comprising: adaptively velocity filtering seismic signals recorded by seismic sensors disposed at selected positions proximate an area of the Earth's subsurface being evaluated, the seismic sensors generating at least one of optical and electrical signals, the at least one of electrical and optical signals conducted to a computer for processing; transforming the velocity filtered signals into a domain of possible spatial positions of a source of seismic events, the transforming comprising causing the recorded seismic signals to correspond to signals that would be detected by a seismic sensor at each selected position if a seismic event had originated at each position in the domain; and determining an origin in spatial position and time of at least one seismic event from space and time distribution of at least one attribute of the transformed seismic data.
