Abstract
We present the application of terrestrial laser scanning (TLS) for
the monitoring and characterization of an active landslide area in
Val Canaria (Ticino, Southern Swiss Alps). At catchment scale, the
study area is affected by a large Deep Seated Gravitational Slope
Deformation (DSGSD) area presenting, in the lower boundary, several
retrogressive landslides active since the 1990s. Due to its frequent
landslide events this area was periodically monitored by TLS since
2006. Periodic acquisitions provided new information on 3D displacements
at the bottom of slope and the detection of centimetre to decimetre
level scale changes (e.g. rockfall and pre-failure deformations).
In October 2009, a major slope collapse occured at the bottom of
the most unstable area. Based on the comparison between TLS data
before and after the collapse, we carried out a detailed failure
mechanism analysis and volume calculation.
