The paper presents the results of physicochemical analyses spring waters in Postomia River valley (Northwest Poland). Multivariate statistical methods, i.e., cluster analysis (CA) and principal component (PCA) were used to assess spatial distribution similarities differences concentrations individual elements. Concentrations macro elements (MEs), trace (TEs) rare-earth (REEs) analysed concernin...

Abstract Centrifuge model tests on slopes subject to shaking and rainfall have been performed examine the response of with shaking-induced cracks subsequent evaluate corresponding landslide-triggering mechanisms. The failure pattern slope then was found different from that only rainfall. When caused shoulder rupture line below, mobilized soil slid along slip surface extended line, main crack be...

Bushmeat hunting constitutes the most immediate threat to wildlife populations in the Udzungwa Mountains of the Eastern Afromontane biodiversity hotspot. This study assesses the impact of hunting by comparing densities of mammalian species between the little hunted West Kilombero Scarp Forest Reserve (WKSFR), the medium-hunted Udzungwa Scarp Forest Reserve (USFR) and the intensively hunted New ...

Stromboli volcano has experienced four sector collapses over the past 13,000 years, resulting in formation of Sciara del Fuoco (SDF); a horseshoe-shaped flank collapse scarp where episodes instability are continuously observed and recorded. A NE / SW striking rift zone across SDF western island is inferred to be potential weakness for further episodes. This study reports new data fracture densi...

Introduction: Defining the nature of the early crust on Mars remains a challenging problem due to the breadth of time and processes that have acted upon it. Concepts of planetary evolution and geophysical modeling suggest that primary crust may have originally formed during cooling of a magma ocean or by serial magmatism [1]. Most consider this early crust to have been broadly basaltic in compo...

Abstract On Mars, basins formed by tectonic processes are rare and mostly have unconstrained subsidence histories. One method for understanding this record of is through associated alluvial fans, which sourced from uplifted areas accumulate in downthrown basins. The source, morphology, superposition fan deposits can be used to reconstruct fault kinematics, the relative timing accommodation spac...

In the northern part of Sumatra Island, Indonesia, Great Sumatran Fault, which can cause an earthquake, was divided into two segments: Aceh and Seulimeum. An effort to reduce risk is mapping fault area, especially in region that does not clearly show sign on surface, e.g., Lamtamot Indonesia. Electrical resistivity widely used study shallow structures, but method requires more time when applied...

Interferometric synthetic aperture radar (InSAR) was used to measure ground deformation during explosive eruptions on 27 and 28 May 2010 at Pacaya volcano, Guatemala. Interferograms produced using spaceborne and airborne synthetic aperture radar data reveal ~3 m of along-slope movement of the southwest sector of the edifice during these eruptions. This is the largest measured slope instability ...
