Land surface waves (MASW and MicroTremor) applied to cavities detections. Development of an urban area
For a project of an urban extension over an area where underground marl pit quarries were suspected a geophysical campaign have been defined. A test area has been defined in order to select the different geophysical approaches.
SismOcean performed a passive seismic campaign based on the MASW and DCOS processing. These two approaches have been validated and selected to be applied over all the area defined by the project.
- Onshore seismic surface wave (MASW)
- Passive acquisition (microtremor measurements)
- Geological anomaly detection
- DCOS analysis
- Karst detection for an urban extension
