“…In this sector, volcanism started at about 0.8 Myr and it is still active at Stromboli. Fumaroles and very shallow seismicity characterizes the submarine zones around Panarea (e.g., the November 2002 episode of increased hydrothermal activity; information available at http://www.ingv.it/panarea/panarea.html) and the eastern seamounts [ Soloviev et al , 1990].…”

Geodynamic significance of the Aeolian volcanism (Southern Tyrrhenian Sea, Italy) in light of structural, seismological, and geochemical data

2003

[1] The Aeolian volcanoes are located between the Southern Tyrrhenian Sea back arc and the Calabrian Arc forearc region. Structural, geochemical and seismological data indicate that the early phases of volcanic activity (1.3 Myr) developed in the western sector along WNW-ESE tear faults controlling the southeastward migration of the forearc -back arc system. This magmatism ceased when delamination processes affected the Calabrian Arc. At 0.8 Myr, the volcanism migrated southeastward and concentrated on the ''new'' formed NNW-SSE tear faults related to the postsubduction extensional strain. The compressive strain deduced by focal mechanism of earthquakes in the western sector explains the volcanism ending. The still active volcanism in the central and eastern sectors develops on a NNW-SSE striking lithospheric discontinuity that crosses the ring-shaped volcanic belt. Moho upwelling occurs in the area of active volcanism. Fault-slip data and focal mechanisms from M > 5 earthquakes indicate that the NNW-SSE discontinuity moves in response to an oblique (strikeslip/normal) stress related to a WNW-ESE extension. This direction of extension is consistent with that of the forearc region, where thrust-type events are lacking and the last compressive phases occurred during Pliocene. The later phases of the Aeolian volcanism are related to the melting of shallower source(s) consistent with a continental rift magmatism. The Aeolian Islands represent a postcollisional, rift-type volcanism emplaced in an older collision zone.

“…In other words, this fault could be regarded as the dividing line between the most ancient (NW) and the younger (SE) sectors. Ocean-bottom seismographs operating in the Southeastern Tyrrhenian Sea in 1987 recorded several shallow volcano-type microearthquakes (M l <3) located between the SE scarp of PS and the Calabrian coast (Soloviev et al, 1990). The presence of this seismic activity, not detected on the near mainland of the Calabria Arc, suggests that EZ of PS could be active.…”

Volcanism in slab tear faults is larger than in island-arcs and back-arcs

et al. 2017

Subduction-transform edge propagators are lithospheric tears bounding slabs and back-arc basins. The volcanism at these edges is enigmatic because it is lacking comprehensive geological and geophysical data. Here we present bathymetric, potential-field data, and direct observations of the seafloor on the 90 km long Palinuro volcanic chain overlapping the E-W striking tear of the roll-backing Ionian slab in Southern Tyrrhenian Sea. The volcanic chain includes arc-type central volcanoes and fissural, spreading-type centers emplaced along second-order shears. The volume of the volcanic chain is larger than that of the neighbor island-arc edifices and back-arc spreading center. Such large volume of magma is associated to an upwelling of the isotherms due to mantle melts upraising from the rear of the slab along the tear fault. The subduction-transform edge volcanism focuses localized spreading processes and its magnitude is underestimated. This volcanism characterizes the subduction settings associated to volcanic arcs and back-arc spreading centers.
