Total CO 2 output from fumaroles, soil gas, bubbling gas discharges and water dissolved gases discharged the island, was estimated for Vulcano Italy. The emission fumaroles La Fossa summit crater SO output, while through diffuse quantified on basis of 730 measurements fluxes performed by using accumulation chamber method. results indicate an overall ≅500 t day −1 island. main contribution to total comes area cone (453 ), with 362 91 degassing. release peripheral areas is ≅20 degassing...
Abstract Amagmatic geothermal systems within regional‐scale orogenic faults are promising renewable resources for heat and possibly electricity production. However, their behavior needs to be better understood improve exploration assessment of energy potential. To provide more insight, we report geochemical, geological, geophysical studies from seven hot spring sites strung along a 90 km segment the Agua Blanca Fault, which traverses mountainous region northern Baja California, Mexico. Our...
Abstract The active cone of La Fossa is a close conduit volcano characterized by solphataric activity, manifested discharging fluids through fumaroles and soil degassing. Since 1978 several degassing crises have been observed interpreted as early signals volcanic unrests. Recently, from June 2021 to May 2022, we measured the changes in soils CO 2 release evaluating level duration actual exhaling crises. output has evaluated surveys carried out anomalously areas, located both summit area...
Open conduit volcanoes like Stromboli can display elusive changes in activity before major eruptive events. Starting on December 2020, volcano displayed an increasing activity, that 19 May 2021 led to a crater-rim collapse, with pyroclastic density currents (PDCs) spread along the barren NW flank, entered sea and ran across it for more than 1 km. This episode was followed by lava flow output from crater rim lasting few hours, another phase of June 2021. These episodes are potentially very...
Abstract Along the Jordan Valley‐Dead Sea Fault area several natural waters in springs, wells, and catchments occur. The chemical‐physical characters of studied allowed for first time investigation Zr Hf geochemical behavior, apart from REE, extended to a wide range Eh, temperature, salinity, pH conditions. results this study indicate that dissolved distribution is strongly influenced by redox conditions since these turn drive deposition Fe‐oxyhydroxides or pyrite. In oxidizing saturated...
The inhalation of natural nanoparticles (NPs) emitted from volcanic activity may be a risk to human health. However, the literature rarely reports fate and response NPs once in contact with lung fluids. In this work, we studied particle size distribution ashfall Popocatépetl volcano, Mexico. collected ashes (n = 5) were analyzed scanning electron microscopy (SEM) obtain elemental composition morphology, determine ash particles using ParticleMetric software (PMS). PMS reported most have...
Abstract Ash emission from volcanic eruptions affects the environment, society, and human health. This study shows total concentration lung bioaccessible fraction of eight potential toxic metal(loid)s in five Popocatépetl ashfall samples. Mineralogical phases particle size distribution were analyzed by X-ray diffraction (XRD) Scanning Electron Microscope (SEM) techniques, respectively. The bioaccessibility test Gamble solution (GS) Artificial Lysosomal Fluid (ALF) conducted to simulate...
