SILVA, R.F., MARQUES, R. (2023) - Monitorização geodésica e inclinométrica de um movimento de vertente: um caso de estudo no lugar da Maia (ilha de Santa Maria, Açores). Livro de Resumos do XI Congresso Nacional de Geologia, Coimbra, Portugal, 53-54.​

​In March 2010, a landslide with 18,500 m² caused several damages at Maia (Santa Maria Island). In order to evaluate the kinematic behaviour and the geometry of the unstable mass, it was architected and implemented a permanent geodetic and inclinometric monitoring network. The results of the geodetic network demonstrates a heterogeneous spatial deformation pattern in the unstable mass. The planimetric and altimetric displacement is higher in the central sector of the landslide, along the topfoot axis of the deposit, with maximum accumulated displacement since 2012 of 0.05 m and 0.01 m, respectively. The failure surface is located between 18.0 m and 18.5 m in depth in the FSM1 borehole and between 15.5 m and 16.0 m in the FSM2 borehole. The maximum accumulated displacement in depth is 18.5 mm and 20.5 mm in the FSM1 and FSM2 boreholes, respectively
