The two most important properties of lava are its viscosity, and the amount of gases dissolved in the liquid rock. Let's look at each of these separately. Viscosity is a term that describes the fluidity or runniness of the lava. Some lavas are very runny, not quite like water, but more like warm honey or hot wax.When these lavas erupt, they flow for large distances before cooling enough to turn solid.olcanic eruptions may be quiet outflows of lava which are so peaceful that one can stand close enough to toss in pebbles (or leis; see figure) or so explosively violent that they blow mountains apart and blast everything within a hundred miles to smithereens (not recommended for close observation).
Some volcanic eruptions are explosive and others are not. How explosive an eruption is depends on how runny or sticky the magma is. If magma is thin and runny, gases can escape easily from it. When this type of magma erupts, it flows out of the volcano.Lava flows rarely kill people, because they move slowly enough for people to get out of their way.Lava flows, however, can cause considerable destruction to buildings in their path.n this type of eruption, the magma blasts into the air and breaks apart into pieces called tephra. Tephra can range in size from tiny particles of ash to house-size boulders. Explosive volcanic eruptions can be dangerous and deadly. They can blast out clouds of hot tephra from the side or top of a volcano.
