Compared with some other volcanoes around the world, the Hawaiian volcanoes are fed by low-viscosity magma with a low gas content. The explosive power of a volcanic eruption is driven by gas trapped in the magma, and magma that is more viscous allows more pressure to build up. The magma in the Hawaiian volcanoes flows out fairly readily.

What kind of magmas produce violent volcanic eruptions?
Those that are rich in iron and magnesium.
What are less well known dangers of volcanic eruptions?
The fumes and chemicals that come out can kill u and/or kill you.
Is mount st Helen's eruptions violent or quiet?
Mount Saint Helens is actually both viloent andquiet
How could collision between two seafloor plates produce volcanic activity?
The more dense plate could move under the less dense plate producing magma which can lead to volcanic eruptions
What type of eruptions do mafic magmas cause?
Basaltic magmas are associated with fissure eruptions creating lava flows spilling out from cracks in the crust. This is because basaltic magmas are more viscous and contain a lower concentration of gases than rhyolitic magma and therefore are unable to build up sufficient pressure to produce explosive eruptions.

How high can volcanic eruptions occur into the air?
That all depends on how viscous the magma (though out of the earth it's called lava) is. More viscous, the bigger and higher it gets. The less viscous, the less violent the explosion can and will be.

Why do volcanic eruptions differ?
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.

What model helps scientists explain earthquakes and volcanic eruptions?
Using a model is less hazardous than studying the volcano close up.

What kind of magma produce violent volcanoes eruptions?
Rhyolitic magma. This type of magma is found where the gases can't escape like in volcanic eruptions. Because the gas can not escape, the magma becomes viscous, resulting in the explosions being violent and unpredictable. The other type of magma is Basaltic magma. This can be found where continent plates are pulling away from each other and the magma is nearer the surface. This allows the gas to escape and therefore the magma is less viscous and doesn't result in explosive volcanoes, here eruptions are gentle and 'rifts' are more likely, where lava is persistent. I hope this helps! :)
What is a good effect of volcanic eruptions?
less chance of it errupting again any time soon also refirtilises the eart / soil makes more land
Are Hawaiians gay?
Hawaiians do not have any more or less chance of being gay than any other humans.
What part of the planet has the less risk of volcanic eruptions and earthquakes?
Any area that is not on or around any plates should be safe from earthquakes. there is no sign on when a volcano will erupt so stay clear of volcanoes.
