Abstract. By virtue of their extreme heat, and their ability to surround and bury, as well as to force structural failure, lava flows present an extreme hazard to communities in their path.Here the focus is on hazards associated with the ingress of basaltic lava into vulnerable areas.bstract. By virtue of their extreme heat, and their ability to surround and bury, as well as to force structural failure, lava flows present an extreme hazard to communities in their path.
Non explosive eruptions are favored by low gas content and low viscosity magmas (basaltic to andesitic magmas). If the viscosity is low, non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When magma reaches the surface of the earth, it is called lava.Since it its a liquid, it flows downhill in response to gravity as a lava flows. Different magma types behave differently as lava flows, depending on their temperature, viscosity, and gas content. This is the most dangerous type of volcanic eruption. 2  The deposits that are produced are called ignimbrites if they contain pumice or pyroclastic flow deposits if they contain non-vesicular blocks. 3  If the gas pressure inside the magma is directed outward instead of upward, a lateral blast can occur.
