Stromboli, in the Aeolian Archipelago, is famous for its persistent volcanic activity. The ‘normal’ activity, consisting of rhythmic explosions ejecting crystal-rich scoriae, periodically interspersed with more energetic during which, addition to crystal-poor pumices are also emitted. scoriae contain ∼50 vol. % crystals (Plag ∼65; Cpx ∼25; Ol ∼10) whereas display <10 ∼42–50; ∼47–30; ∼11–20). bulk rocks, mainly ranging between K-rich basalts and shoshonitic basalts, surprisingly exhibit only...
Stromboli is known for its persistent degassing and rhythmic strombolian activity occasionally punctuated by paroxysmal eruptions. The basaltic pumice scoria emitted during paroxysms activity, respectively, differ in their textures, crystal contents glass matrix compositions, which testify to distinct conditions of crystallization, magma ascent. We present here an extensive dataset on major elements volatiles (CO2, H2O, S Cl) olivine-hosted melt inclusions embayments from pyroclasts emplaced...
Paroxysms at Stromboli are the most violent manifestations of persistent activity and related to emission small volumes (10 3 –10 5 m ) nearly aphyric HK‐basaltic pumices. They offer exceptional opportunity detail mixing‐crystallization‐degassing processes that occur in a steady state basaltic arc volcano. We present mineralogy, major, volatile, trace element geochemistry olivine‐hosted melt inclusions these In all paroxysms, hosted olivines Fo 88–91 have recorded parental melts rich CaO (up...
Red Pompeian paintings, very famous for their deep intensity, are currently suffering from darkening. The origins of this darkening degradation not clearly identified yet and remain a major issue curators. In the specific case cinnabar (HgS)-based red pigment, photoinduced conversion into black metacinnabar is usually suspected. This work focused on blackening paintings coated sparry calcite mortar. Different samples exhibiting different levels were selected upon visual observations analyzed...
Abstract Campi Flegrei is an active volcanic area situated in the Campanian Plain (Italy) and dominated by a resurgent caldera. The great majority of past eruptions have been explosive, variable magnitude, intensity, their vent locations. In this hazard assessment study we present probabilistic analysis using variety volcanological data sets to map background spatial probability opening conditional on occurrence event foreseeable future. focuses reconstruction location eruptive vents last 15...
Abstract Stromboli, the northernmost island of Aeolian archipelago, is known for its persistent volcanic activity over last several centuries and cone which, on clear days, surmounted by a gas plume rising from summit. The hosts two settled areas: village Stromboli ( c. 500 inhabitants) to NE that Ginostra 40 SW, both situated along coast. In summer number residents grows considerably, reaching 5000 people. This paper provides description present reassesses hazards basis data new monitoring...
We provide a database of the coseismic geological surface effects following Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one strongest seismic events to occur in Europe past thirty years, causing complex ruptures over an area >400 km2. The originated from collaboration several European teams (Open EMERGEO Working Group; about 130 researchers) coordinated by Istituto Nazionale di Geofisica e Vulcanologia. observations were collected performing detailed field...
Abstract Campi Flegrei (CF) is an example of active caldera containing densely populated settlements at very high risk pyroclastic density currents (PDCs). We present here innovative method for assessing background spatial PDC hazard in a setting with probabilistic invasion maps conditional on the occurrence explosive event. The encompasses assessment potential vent opening positions, derived companion paper, combined inferences about distribution areas from simplified flow model, informed...
The 5 April 2003 paroxysm of Stromboli occurred during an ongoing effusive episode that initiated on 28 December 2002. It mainly consisted in two, a few seconds apart cannon‐like explosions followed by vertical gas/pyroclast jet. HK‐basaltic pumices, were generated, contain crystals drained back from the shallow parts plumbing system. Few euhedral to anhedral olivines and their melt inclusions testify crystal fractionation possible mixing between magmas variable volatile content, extent...
Siwi caldera, in the Vanuatu arc (Tanna island), is a rare volcanic complex where both persistent eruptive activity (Yasur volcano) and rapid block resurgence (Yenkahe horst) can be investigated simultaneously during post-caldera stage. Here we provide new constraints on feeding system of this complex, based detailed study petrology, geochemistry volatile content Yasur–Siwi bulk-rocks melt inclusions, combined with measurements chemical composition mass fluxes Yasur gases. Major trace...
Textures, petrography and geochemical compositions of products emitted during the onset 2011–2012 submarine eruption (15 October, 2011) off coast El Hierro have been investigated to get information on interaction mechanism between first rising magma crust as well storage plumbing systems beneath volcano. Studied consist 5–50 cm bombs with an outer black greenish, vesicular bulk basanite composition containing pumiceous xenoliths (xenopumices). Our results show that xenopumices are much more...
Abstract. We present a detailed chronological reconstruction of the 2011 eruption Cordón Caulle volcano (Chile) based on information derived from newspapers, scientific reports and satellite images. Chronology associated volcanic processes their local regional effects (i.e. precursory activity, tephra fallout, lahars, pyroclastic density currents, lava flows) are also presented. The had severe impact ecosystem various economic sectors, including aviation, tourism, agriculture fishing...
Abstract Stromboli volcano (Italy), always active with low energy explosive activity, is a very attractive place for visitors, scientists, and inhabitants of the island. Nevertheless, occasional more intense eruptions can present serious danger. This study focuses on modeling estimation their inter-event time temporal rate. With this aim we constructed new historical catalog major explosions paroxysms through detailed review scientific literature last ca. 140 years. The includes calendar...
Deciphering the triggering mechanisms of violent explosive activity is broad interest for understanding dynamics basaltic open-vent volcanic systems. For nearly 1300 years Stromboli has been renowned not only its continuous degassing and mild explosions at summit craters, but also short-lived, events variable scale, known as major paroxysms. Here, we focus on 1456 1930 paroxysms most recent events, in July August 2019 Stromboli. We show that shallow phenomena such flank collapse, lava...
