Possible evaporite karst in an interior layered deposit in Juventae Chasma, Mars
Davide Baioni and Mario Tramontana

  • Karst morphologies are detected in an ILD in Juventae Chasma
  • The landforms display similarity with terrestrial karst
  • The features of the karst landforms suggest a young erosional age
  • The landforms suggest the presence of liquid water
  • The landforms are markers of climatic changes occurred in the early Amazonian period

Integration of multi-criteria and nearest neighbour analysis with kernel density functions for improving sinkhole susceptibility models: the case study of Enemonzo (NE Italy)
Chiara Calligaris, Stefano Devoto, Jorge P. Galve, Luca Zini, and José V. Pérez-Peña

  • The Alta Valle del Tagliamento valley (N Italy) is affected by hundreds of sinkholes
  • A susceptibility model of high forecast performance was produce for the Enemonzo area
  • The parameter Nearest Sinkhole Distance and the use of kernel density estimations improved the model significantly
