Etna discrete geodetic networks
North-South kinematic profile
The North-South kinematic profile covers a strip of the volcano edifice above 2000 m of altitude, crossing the summit craters area. Several other important active volcanic structures are monitored by this network (e.g. the 1983-85 and 1989-91 fracture zones and the NE Rift zone). It also allows the reduction of gravity data collected in the same area. It is entirely constituted by self-centering benchmarks and it is surveyed using the same strategy adopted for the EW profile. The upper southernmost stations of the profile have been destroyed by the 2001 and 2002 eruptions, so the profile currently develops over the NE rift up to the summit craters. The upper southern part has been replaced by new stations surveyed in static mode.
