... effects associated with earthquakes. Two different types of waves are usually distinguished: high power frequency (around 20 kHz) and low power frequency waves (e.g. 40 Hz). High power frequency waves have a local effect in the reservoir and are mainly applied for wellbore stimulation. Their effects...
