A new Digital Elevation Model (DEM) of the natural landforms Italy is presented. methodology discussed to build a DEM over wide areas where elevation data from non-homogeneous (in density and accuracy) input sources are available. The include contour lines spot heights derived Italian Regional topographic maps, satellite-based global positioning system points, ground based radar altimetry data. Owing great heterogeneity density, format that better preserves original accuracy Triangular...
Abstract. The Mediterranean region and the Levant have returned some of clearest evidence a climatically dry period occurring around 4200 years ago. However, regional is controversial contradictory, issues remain regarding timing, progression, articulation this event. In paper, we review from selected proxies (sea-surface temperature, precipitation, temperature reconstructed pollen, δ18O on speleothems, lacustrine carbonate) over Basin to infer possible climate patterns during interval...
Variations in the intensity of high-latitude Northern Hemisphere summer insolation, driven largely by precession equinoxes, are widely thought to control timing Late Pleistocene glacial terminations. However, recently it has been suggested that changes Earth's obliquity may be a more important mechanism. We present new speleothem-based North Atlantic marine chronology shows penultimate termination (Termination II) commenced 141,000 +/- 2500 years before present, too early explained...
A stochastic model, named DOWNFLOW, is presented to forecast possible lava flow paths with the aim of hazard assessment and mitigation. The model relies on fact that emplacement is, in many cases, controlled by topography. potential inundation area determined considering a number steepest over perturbations original Since code requires very short computational time few input data proved be useful tool obtain real‐time predictions during initial phase an eruption. necessary topographic...
In this study, Mg/Ca, Sr/Ca and Ba/Ca ratios in a Lateglacial to Holocene stalagmite (CC26) from Corchia Cave (central Italy) are compared with stable isotope data define palaeohydrological changes. For most of the record, trace element show small absolute variability but similar patterns, which also consistent variations. Higher element-to-calcium values interpreted as responses decreasing moisture, inducing changes residence time percolation, producing prior calcite precipitation and/or...
Abstract Relatively few radiometrically dated records are available for the central Mediterranean spanning marine oxygen isotope stage 6–5 (MIS 6–5) transition and first part of Last Interglacial. Two flowstone cores from Tana che Urla Cave (TCU, Italy), constrained by 19 U/Th ages, preserve an interval continuous speleothem deposition between ca. 159 121 ka. A multiproxy record (δ 18 O, δ 13 C, growth rate petrographic changes) obtained this preserves significant regional-scale hydrological...
Abstract Continental rift systems form by propagation of isolated segments that interact, and eventually evolve into continuous zones deformation. This process impacts many aspects rifting including morphology at breakup, eventual ocean-ridge segmentation. Yet, segment growth interaction remain enigmatic. Here we present geological data from the poorly documented Ririba (South Ethiopia) reveals how two major sectors East African rift, Kenyan Ethiopian rifts, interact. We show formed...
Morphostructural data derived from Lidar (Light detection and ranging) surveys carried out on Mount Etna in 2005 2007 are compared with earlier aerophotogrammetric 1986 1998. These render an unprecedentedly clear quantitative image of morphostructural volumetric changes that have affected the summit area volcano past two decades permit production a new topographic map. The computed volume gain during 1986–2007 period amounts to 112 ± 12 × 10 6 m 3 , at mean annual rate ∼5.3 . comparison...
Abstract. We present new data on the 4.2 ka event in central Mediterranean from Corchia Cave (Tuscany, Italy) stalagmite CC27. The was analyzed for stable isotopes (δ13C and δ18O) trace elements (Mg, U, P, Y), with all proxies showing a coherent phase of reduced cave recharge between ca. 4.5 4.1 BP. Based current climatological cyclogenesis, reduction is considered to be associated weakening cyclone center located Gulf Genoa response advection air masses Atlantic during winter. These...
Abstract Disentangling the effects of climate and human impact on long-term evolution Earth Critical Zone is crucial to understand array its potential responses ongoing Global Change. This task requires natural archives from which local information about soil vegetation can be linked directly parameters. Here we present a high-resolution, well-dated, speleothem multiproxy record SW Italian Alps, spanning last ~10,000 years interglacial (Holocene). We correlate magnetic properties carbon...
Historical archives for the Roman Monarchic and Republican periods (753–29 BCE) offer a highly resolved series of observations environmental climatic phenomena in Central Italy. This paper presents new collection these historical archives, gathering 319 across period. We introduce character point out aspects affecting their analysis interpretation reconstruction past conditions Italy latter half first millenium BCE. Archival information is seen to be generally reliable from fifth century BCE...
Current warming and human activity have negatively impacted the hydrological budget of some larger lakes in Balkan region. To explore potential climatic analogues for recent period we investigated a speleothem record from Golubarnica Cave North Macedonia focusing on changes occurring during Medieval Climatic Anomaly (MCA). The δ18O petrography identify drier conditions between ca. 800 1250 CE, chronologically consistent with MCA. This is broadly lake lowstands Prespa Dojran obtained by...
Understanding the long-term interactions among vegetation, fire, and climate is critical for interpreting ecosystem responses to climatic perturbations. Project Prometheus investigates Holocene paleofire dynamics, vegetation shifts, variability in Mediterranean, using speleothem records from caves Italy (Alps, Apennines, Sardinia) Balkans. By integrating multiple proxies, including polycyclic aromatic hydrocarbons (PAHs) as fire markers n-alkanes a proxy composition terrigenous input, this...
The morphological features of active lava channels acquired over Mt. Etna by means airborne laser altimeter data are presented. were on 16th September 2004, using an Optech ALTM 3033 altimeter. flight height was about 2000 m above ground. During the flight, lava, erupted from eastern part summit area, flowed into Valle del Bove. measured morphologic are: channel width (Wc), flow (Wf), levee (Hl), thickness (Tf), and depth (Dc). main shows a well‐developed with levees. average values for this...
An application of light detection and ranging (lidar) intensity for the identification mapping different lava flows from Mount Etna (Italy) active volcano is described. In September 2004 an airborne lidar survey was flown over summit sectors Etna. The information derived values used to compare with respect their age emplacement. Analyzed vary in between those dating prior A.D. 1610 during (2004–2005 eruptions). target‐emitter distance, as well surface roughness texture at footprint scale,...
