摘要:Abstract(#br)The generation of multiple, neutrally-buoyant intrusions by a single, bubble-rich plume [Asaeda and Imberger, J. Fluid Mech. 249 (1993) 35–57] and plume bifurcation [Ernst et al., Bull. Volcanol. 56 (1994) 159–169; Lavelle, J. Geophys. Res. 102 (1997) 3405–...

摘要:Abstract(#br)The dissected volcanic terrains around Limbe, SW Cameroon are frequently affected by small scale but destructive landslides. In this study, a raster-based data driven method involving seed cells is used to build a landslide susceptibility model for the Limbe area. Fa...

摘要:Abstract(#br)Well-preserved tephra fall deposits display thickness variations which are more complex than simple exponential thinning. On plots of log thickness against square root of area enclosed by an isopach contour, many deposits show two or more approximately straight-line ...

摘要:Abstract(#br)As for many other effusive volcanoes, Mount Cameroon (MC) is a volcano for which only limited information exists on lava flow properties and emplacement dynamics for recent eruptions. This study provides new quantitative constraints for rheological and dynamic c...

摘要:Abstract(#br)The aggregation of volcanic ash particles within the eruption column of explosive eruptions has been observed at many volcanoes. It influences the residence time of ash in the atmosphere and the radiative properties of the umbrella cloud. However, the informatio...

摘要:Abstract(#br)Volcanic cones are the most common volcanic constructs on Earth. Their shape can be quantified using two morphometric ratios: the crater/cone base ratio (W cr /W co ) and the cone height/width ratio (H co /W co ). The average values for these ratios obtained over ent...

摘要:Abstract(#br)In regions of frequent low-energetic explosive eruptions such as cinder cone fields, ejecta cone forming eruptions are the prime hazard whether from roof collapse or as a hazard to aircraft safety. So, observations and data for ejecta constructs and construct-fo...

摘要:Abstract(#br)The goal of this paper is to determine the parameters that control the aggregation efficiency and the growth rate of volcanic particles within the eruption column. Numerical experiments are performed with the plume model ATHAM (Active Tracer High resolution Atmo...
