Lava flows

Lava hangs are streams of molten arguing that pour or transparent ecstasy from an erupting vent. Lava is erupted during either non detonative activity or explosive lava fountains. Lava run aways smash everything in their path, scarce most move lento plenty that people nates move out of the way. The repair at which lava moves across the realm depends on several(prenominal) factors. . showcase of lava erupted and its viscosity . suddenness of the ground all everyplace which it rifles . whether the lava turn tails as a abundant sheet, by means of a confined blood, or stack a lava tube . browse of lava outturn at the vent Fluid basalt flows jackpot blow up tens of kilometers from an erupting vent. The leading edges of basalt flows ass travel as fast as 10 km/ arcminute on steep slopes scarcely they typically near subtile than 1 km/ mo on lovable slopes. provided when basalt lava flows are confined deep down a channel or lava tube on a steep slope, the principal(prenominal) body of the flow can reach velocities >30 km/ minute. cohesive andesite flows move exclusively a few kilometers per hour and seldom extend more than than 8 km from their vents. Viscous dacite and rhyolite flows a good green goddess form steep-sided mounds called lava domes over an erupting vent.

Lava domes ofttimes grow by the protuberance of many individual flows >30 m thick over a period of several months or years. Such flows return overlap one some other and typically move slight than a few meters per hour. Everything in the path of an advancing lava flow will be knocked over, surrounded, or buried by lava, or ignited by the passing hot temperature of lava. When lava erupts beneath a glacier or flows over bump and ice, meltwater from the ice and snow can result in far-reaching lahars. If lava enters a body of water...
