Volcanoes can have runny or sticky molten rock which one is fairly safer?

Sticky magma is more dangerous. The more viscous magma tend not to come out as lava flows, but often come out explosively, producing fast-moving avalanches of hot ash and gas called pyroclastic flows.

What are runny and sticky lava?
Runny lava contains low amounts of silicon, whereas sticky lava contains high amounts of silicon.
Which type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
Does a shield volcano have runny lava?
In volcanoes that have lower amounts of volcanic gases in the magma. A good example is the volcanoes in the Hawaiian islands. Volcanoes with more gases in the magma tend to erupt explosively (Mt. St. Helens, Vesuvius) and have a thicker, slower moving lava.
Why are volcanoes in Hawaii the least severe?
The volcanoes in Hawaii erupt basaltic lava, which is relatively runny and has a low gas content. As a result the volcanoes usually produce effusive eruptions; fountain or oozing lava but rarely producing explosions. After emerging the lava travels along as fairly slow-moving lava flows. These flows can be destructive, but are easy to escape.
How do you know that many of the volcanoes in the western district of Victoria had runny lava?

What are the two types of magma and what makes them different?
I'm not sure... but the two different types of lava are: Viscous - sticky and slow moving, resulting in tall volcanoes Non Viscous - runny and fast moving, resulting in short and very spread out volcanoes (shield volcanoes)
What are Produced by volcanoes?
Shield volcanoes are produced by runny lava. That's why they have sloping sides and are like giant shields on the ground. The runny lava can't build up easily.
What are the characteristics of magma associated with shield volcanoes?
Basaltic, runny magma.

Pyroclasic materials from shield volcanoes?
Pyroclastic flows don't come from shield volcanoes. They come from cinder cone and sometimes composite volcanoes. Shield volcanoes only erupt runny lava.
Is basaltic lava sticky or fast running?
well, since basaltic lava is the same material that composes the ocean floor, it is common sense that it would be sticky, not runny.
What type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
How steep are shield volcanoes?
Shield volcanoes almost always emit very fluid or runny lava that spreads over a wide distance, so these volcanoes are not steep.Yes and no, it depends where and how the volcano forms, when it discombobulates, and so on.
