Shallow seismic reflection method is a commonly used technique in urban active fault detection,however,special geotectonic environment may sometimes make reflection survey inapplicable.

The shallow seismic detection method for the urban active fault control;

Exemplified by some results obtained from the electric imaging detection of active faults in Zibo City,this paper described the method for geological interpretation and analysis of images from the electric imaging technique,and studied the input impedance range of the instrument for urban active fault detection as well as some problems which deserve attention in data processing and inversion.

Seismic refraction method is tentatively used in the exploration of urban active faults where strong interference of surface waves exists and it is difficult to use seismic reflection survey.

The paper introduces aim and meaning of exploring urban active faults; researches the examples of exploring earthquake active faults at home and abroad.

To study canonical acquisition and processing technique of ultra-shallow seismic data for detecting urban active faults in Urumqi is provided with great typicality and applied value, and can support vital reference for detecting urban active faults in Urumqi and other areas of all the country i.

Application of exploring methods on urban active faults and some common key technical problems;
