| Zusammenfassung |
| A hazard assessment has been performed on rock slopes impending over a
segment of the Taorminese Road, which connects two popular tourist
destinations in northeastern Sicily: the urban centers of Taormina and
Castelmola. The road crosses steep rock slopes with a complex geological
and tectonic history. The section of the road close to Castelmola is often
affected by rockfall phenomena, causing injury to people and serious damage
to buildings and traffic. The study analyzes the geostructural setting of
the unstable rock masses, by evaluating their mechanical properties and the
kinematics of potential failures. Rockfall simulations confirm that falling
rocks would involve the Taorminese Road with different kinetic energy rates
and prove useful for suggesting the most suitable mitigation technologies
for future remedial works. The modified Rockfall Hazard Rating System has
been applied to highlight the different levels of hazard along the road. The
compiled hazard map shows that portions of the slopes need urgent remedial
works, especially because Taorminese is the only access road to Castelmola
and its interruption would lead to the isolation of the village. |
