Land surface waves (MASW and MicroTremor DCOS) applied to cavities detections
For the maintenance of the road showing a risk of underground quarries, gypsum dissolution, a seismic campaign has been performed.
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.
Passive (microtremor) measurements have been performed.
MASW and DCOS analyses have been used to investigate the underground
Depth investigation about 20 meters
- Onshore seismic surface wave (MASW)
- Passive acquisition (microtremor measurements)
- Geological anomaly detection
- DCOS analysis
