摘要: Abstract Examination of the volcanic stratigraphy deposits younger than 10,000 years on Lipari indicates four principal periods activity related to specific centers. The products from each different center are defined as volcano-stratigraphic unit (VSU). From oldest these are: Canneto Dentro, Gabellotto-Fiume Bianco, Forgia Vecchia and Monte Pilato-Rocche Rosse VSUs. study textures dispersal permitted vents be localized recent history reconstructed. event formed a small explosion breccia cone with final obsidian lava in Dentro area. Immediately afterward, complex series explosions produced widespread dry-surge Bianco sequence. This ended extrusion domical flow. renewal occurred Pirrera area an explosive eruption that deposits. last eruptions this vent were coeval first M. Pilato. rim was partially destroyed by Pilato grew very short period time due continuous swarm events. After repose time, more energetic superficial through slightly south. Rocche flow (about 729 A.D.) cycle activity. All centers follow quite similar stochastic pattern starting fall or surge ending effusion viscous rhyolitic lavas. aligned along either NW-SE NE-SW fault systems according structural island. They can placed into two groups: Dentro-Gabellotto Vecchia-M. A long quiescence ( ⋍ 3,500 ) separates groups while inside activities nearly contemporaneous rapid succession.
