Destruction of the Lava Dome of an Underwater Volcano

Resumo

The stress state and destruction of the lava dome of the underwater volcano exposed to temperature gradients and external pressure from hot magma melt and the cold water layer are investigated. Methods of the linear elasticity theory and statistical strength theory are used for mathematical modeling of the behavior of lava domes. It has been revealed in the course of evaluation calculations that the role of temperature gradients in the lava dome destruction process is as important as that of an external pressure. It is established that the lava dome is destroyed layer by layer, and the time of this destruction is determined in this paper.
