In this paper, we present a physics motivated modeling method for volcanic clouds as a two fluids model. Some previous methods model smoke or clouds as one fluid, but the volcanic clouds can not be treated as one fluid. The volcanic clouds consist of the pyroclasts, the volcanic gas and the entrained air. Since the pyroclasts and the volcanic gas can be treated as one fluid, called magma, the v...

Volcanic hazards assessment tools are essential for risk mitigation of volcanic activities. A number of offline volcanic hazard assessment tools have been provided, but in most cases, they require relatively complex installation procedure and usage. This situation causes limited usage of volcanic hazard assessment tools among volcanologists and volcanic hazards communities. In addition, volcani...

the present investigation attempted to develop the ceramic adsorbent media in order to remove the mercury from aqueous phase. two ceramics, akadama volcanic ash soil-ceramic (aceramic) and improved magnesium oxide impregnated akadama volcanic ash soil-ceramic (maceramic) were produced from raw akadama volcanic ash soil by heating process to determine the hg(ii) adsorption capacity. adsorption e...
