Volcanic eruptions are complex phenomena that involve the dynamics of magma transfer, starting of volcanic unrest, interaction with the volcanic edifice, eruption of magma and gases, and finally the atmospheric transport of volcanic ash and aerosols. The violent activities involved in the volcanic eruption classifies it as a natural hazard. There are several hundreds of active volcanoes in our earth and millions of people risk their lives as they tend to live in the range of potential threat. The most serious concern regarding volcanic activity is its impact on air traffic, weather and pollution through the erupted volcanic gases and aerosols. One of the central issue in the volcanic eruption is the successful determination of the heights reached by the volcanic plume. It determines the effective monitoring of the volcanic ash and gases required for aviation safety, climatic studies and air quality.
