Paper presented at the SEG/AAPG International Meeting for Applied Geoscience & Energy, August 26–29, 2024
Paper Number: SEG-2024-4092022
... Timely identification, prevention, and mitigation of disasters in urban settlement is nonnegotiable. Lives, properties, and civilization are under serious threats if cavities form unnoticed because natural lakes, ponds and sinkholes may ensue. Some researchers have proposed methods...

... Hazardous cavities may develop beneath road surface as a result of underground constructions and leaking pipelines. Road surface may suddenly collapse if a cavity keeps growing without being noticed and treated. Therefore, monitoring and forecasting are essential in the prevention of geo-hazard...
