Magic Sheet 21 Marsili — Map (OpenData)

The sheet includes the entire volcanic apparatus of Marsili, characterised by a length of about 50 km in the North East-South West direction, a width of 20 km and a height of about 3 km. The main element of the volcano is an axial rift area where volcanic products are placed in place along elongated cracks fed by dicks. Two fields of volcanic buildings they characterise the north-western and western sides of Marsili. The first consists of some flat-top volcanoes, a series of conical buildings and a staircase of overlapping lava terraces, the second consists mainly of conical buildings. Areas affected by gravitative instability are present in the northern portion of the volcano. The top rift area, at a depth of less than 1 000 m, represents an area of geological danger. Fissural eruptions fed by dick could potentially be able to induce the trigger of gravitative instability of the building’s hips. A critical point associated with the eruptive rift of the volcano has been detected. CNR-ISMAR
