Abstract
During monitoring since 2005 to 2008 at the Astrakhan gas-field it has been recorded three technogenic earthquakes. Results of geodetic levelling for the given period allow to approve that seismic event is preceded by raisings of a surface and its subsequent subsidence as a its result of unloading. That allows to use geodetic levelling for the forecast of technogenic seismic phenomena for oil and gas fields.
