Slopes instability phenomena and mitigation techniques after october 2017 wildfires in serra da estrela region

Abstract

The probability of occurrence of slopes instability phenomena increases after wildfires, being usually triggered by periods of heavy precipitation or earthquakes. In order to minimize incidents or mitigate their effects, which can be delayed over time, various techniques of soil conservation and/or water infiltration may be used. This communication presents the geotechnical incidents registered in the region of Serra da Estrela (Portugal), as well as the slopes stabilization techniques employed after the October 2017 wildfires.
