Analysis of building deformation in landslide area using multisensor PSInSAR ™ technique

View Article: PubMed Central - PubMed

ABSTRACT

We analyze ground deformation velocities of the buildings in San Fratello (Sicily, Italy).

We analyze satellite PSI data using different sensors, acquired from 1992 to 2012.

We performed a damages assessment map after the landslide occurred on the 14th February 2010.

The obtained data were compared to evaluate the residual risk.

The obtained data were compared to evaluate the residual risk.

No MeSH data available.

Mentions: The town of San Fratello is located in the northeastern sector of Sicily (Italy), along the Tyrrhenian coastline (Fig. 1), close to the boundary between the Nebrodi and Peloritani mountain chains. The study area was historically affected by landslides (Goswami et al., 2011, Mondini et al., 2011, Del Ventisette et al., 2012, Bianchini et al., 2014b). The oldest documented one occurred in 1754, destroying the north-eastern part of the town, medieval in age. The 8th of January 1922 another large landslide seriously damaged the north-western quarters, causing the town delocalization. The most recent landslide occurred on February 14th 2010 causing several damages to buildings and infrastructures. This landslide affected the eastern sector of the town, determining the evacuation of more than 2000 people. From a geomorphological point of view San Fratello is located at about 650 m a.s.l. along a N–S oriented divide on which both the west and east facing slopes are characterized by a steep gradient and creek erosion at their toe.
