high resolution seismograph seismic instrument seismic refraction

  • Reflection seismology

    Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves.The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator, commonly known by the trademark name Vibroseis.

  • High Resolution Seismic Refraction Tomography for

    High resolution seismic refraction tomography has proved to be a useful tool to effectively estimate depth of blast induced damage in a mine face. Excavation blast . damage can be as shallow as 1 to 2m and requires resolution at a fraction of a meter . for effective imaging. We used an accelerometer with lat frequency response to
