This paper presents an application of geophysical methods to evaluate the risk associated with blasting used during rock excavation at highly populated and risky urban areas. Ground penetration radar provided information related to rock mechanics such as fracture density, whilst seismographic readings helped in maintaining vibration levels below maximum limits. Results of in situ soil and rock characterization and vibration control are reported and discussed. The methodology proposed is illustrated in case study.
