Etna discrete geodetic networks

Main inner network
The principal inner network covers the volcano from 600 to 2900 m a.s.l.. Its evolution is closely related to the dynamics of the volcano during the last decades and to the different research activities carried out on Etna using geodetic techniques. Following the strategy defined during the first 1988 survey, several benchmarks were installed in order to connect the GPS network to the existing microgravimetric and E.D.M. networks on the volcano. This sub-network is robustly connected to the reference frame and allows the ground deformation events involving the whole volcanic edifice to be monitored.
