Question

Which characteristics would create the highest risk zone for lava flows: (choose all that apply)

Question 7 options:

	in low lying areas like river valleys
	only close to the volcano (within 10km or so)
	associated with shield volcanoes
	within 100km of the volcano, but closer would have increased risk
	associated with stratovolcanoes/composite volcanoes

Answer 1

Ans- in low lying areas like river valleys

associated with shield volcanoes

within 100km of the volcano, but closer would have increased risk

Shield volcanoes are associated with emplacement of less viscous lava. The less the viscosity the more the distance it can cover. That's why it has the ability to cover hundreds of kilometres. Thee type of lava flows covering a large distance is also called as large igneous provinces.
