This patent describes a seismic detector for high resolution reverse vertical seismic profile measurements when placed in a shallow borehole in a geological formation of interest that contains a seismic source and connected to a seismograph. It comprises a framework; accelerometer sensors for X, Y, and Z axis, means for electrically connecting the accelerometers to the seismograph to record seismic waves received by the accelerometer sensors form the seismic source; heating elements secured to, but electrically insulated from, the framework; power means for supplying power to the heating elements; and meltable substance encapsulating the seismic detector.
