Land surface waves (MASW and MicroTremor) applied to cavities detections


DCOS analysis is a processing developed and patented by SismOcean to detect and localize every kind of geological anomalies (voids, karts, break of layer horizontality, outcrop …) using the properties of propagation of the surface wave.
This site known by SNCF has been chosen to test the DCOS/MASW processing in a karst conditions

  • Onshore seismic surface wave (MASW)
  • Passive acquisition (microtremor measurements)
  • Geological anomaly detection
  • DCOS analysis
