The perimeters of the Oued-Souf region are irrigated by salty water coming from phreatic and thus progressive salinization soil occurs. This study aims at a qualitative analysis evolution salinity in soils pivot irrigation for several years. For this, three plots were pivots each agricultural region. choice these 3 is justified number years their cultivation: plot 1 has been cultivated 2 (2016–...

The H20, CO2 and H2S outputs at the Solfatara of Pozzuoli have been measured and a map of the exhaling areas has also been made. The energy released at the surface by the fluids has been estimated to be 1019 ergs/day. The presence of aquifers at Phlegraean Fields increases the phreatic and phreatomagmatic explosion risk. Our results suggest that even if an uprising magma may interact with water...

by Craig Abram Jordan, M.S. Washington State University Chair: Balasingam Muhunthan Landslides constitute a major geological hazard in the world due to their high financial cost and their nondiscriminatory nature. The Olympic Region of Washington State has many potential triggers of landslides, but prolonged periods of high rainfall is the most commonly attributed trigger of landslides. The cur...

Finite element method (FEM) based analysis using the SEEP/W and SLOPE/W sub-programme options of a GEOSTUDIO software was used to analyze Saura-Keffi earth dam in Nasarawa State, Nigeria with view seepage its stability. The created geometry assigned material properties boundary conditions at reservoir water levels of: minimum (3 m), normal (6 m) maximum (7 m). conducted under cases that without...

A gas blowout during an unauthorized well drilling occurred on June 9, 2020 at the Rome-Ciampino boundary periphery of Colli Albani quiescent volcano. This zone hosts a shallow confined gas-pressured aquifer, which recently produced further three blowouts. Dangerous atmospheric CO2 and H2S concentrations killed some birds, 12 families were evacuated. The helium isotopic composition indicates th...

Reason for Corrigendum: In the original article (Palladino et al., 2015), there was an error in Figure 1. The vertical axis of the qualitative plot reported erroneously “ratio of juvenile to lithic materials in deposits outside of depression”. The correct wording is as follows: “ratio of juvenile to total (i.e., juvenile+lithic) materials in deposits outside of depression”. In fact, as it was r...
