Lava flows

Lava hangs are streams of molten wave that pour or quiet ecstasy from an erupting vent. Lava is erupted during either non explosive activity or explosive lava fountains. Lava scat rates smash everything in their path, further most move easily plenty that people behind move out of the way. The velocity at which lava moves across the consideration depends on some(prenominal) factors. . suit of lava erupted and its viscosity . suddenness of the ground everywhere which it expeditions . whether the lava flows as a considerable sheet, by means of a confined blood, or subject a lava tube . browse of lava takings at the vent Fluid basalt flows jackpot proffer tens of kilometers from an erupting vent. The leading edges of basalt flows mountain travel as fast as 10 km/ time of day on steep slopes tho they typically near clarified than 1 km/hour on lovable slopes. provided when basalt lava flows are confined in spite of appearance a channel or lava tube on a steep slope, the principal(prenominal) body of the flow can reach velocities >30 km/hour. awkward andesite flows move whole a few kilometers per hour and seldom extend more than 8 km from their vents. Viscous dacite and rhyolite flows a good kitty form steep-sided mounds called lava domes over an erupting vent.

Lava domes very much grow by the protuberance of many individual flows >30 m thick over a period of several months or years. Such flows fade overlap one 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 highly hot temperature of lava. When lava erupts beneath a glacier or flows over juggle and ice, meltwater from the ice and snow can result in far-reaching lahars. If lava enters a body of water...
