An explosive eruption would be more likely to increase the steepness of a volcanic cone. In a quiet eruption, the lava flows and spreads out over a large area. In an explosive eruption, pyroclastic material piles up much higher. That’s why cinder cone volcanoes have steeper sides than shield volcanoes.
Eruptions occur when pressure inside the volcano increases, … quiet eruptions is runny lava, while the most explosive eruptions spew forth …
Quiet eruptions FTW! Explanation: You see, when there’s an explosive eruption parts of the crater falls or flies away in the explosion.
What is the difference between a quiet eruption and an explosive eruption?
The difference between a quiet and explosive eruption is the silica content. In a quiet eruption, the magma is low in silica, allowing the magma to flow out gently. In an explosive eruption, the magma is high in silica, which causes the magma to be thick and sticky.
What type of volcano is steeper and usually erupts more violently?
Because they form in a system of underground conduits, stratovolcanoes may blow out the sides of the cone as well as the summit crater. Stratovolcanoes are considered the most violent. Mount St. Helens, in Washington state, is a stratovolcano that erupted on May 18, 1980.
What happens when a volcano erupts quietly?
Quiet Eruptions Volcanoes that have very hot, low-silica magma generally erupt quietly. In a quiet eruption, lava erupts in a stream of low-viscosity lava, called a lava flow. Lava flows from a quiet eruption can travel for great distances.
What do quiet and explosive eruptions have in common?
What do quiet eruptions and explosive eruptions have in common? Although quiet eruptions and explosive eruptions produce different hazards, both types of eruption can cause damage far from the crater’s rim.
What type of volcano has a quiet eruption?
Shield volcanoes, those with broad, gentle slopes, produce the quietest eruptions. The Hawaiian Islands are not only home to active shield volcanoes, but the chain is actually built entirely by them.
Was Mount St Helens a quiet eruption?
Many of the scientists now observing Mount St. Helens were there when it erupted in 1980 and continued to observe the mountain as a series of 16 smaller eruptions, some lasting only a few days, continued through 1986. Then the mountain fell quiet, and the scientists did not expect another eruption in their lifetimes.
What are silent volcanoes?
Volcanologists have shown that periods of seismic quiet occur immediately before eruptions and can be used to forecast an eruption. The duration of the silence can indicate the level of energy that will be released. Longer quiet periods mean a bigger bang.
Which kind of magma produces a quiet volcanic eruption?
Low-silica magma, called basaltic, is fluid and produces a quiet, nonexplosive eruption.

Phreatomagmatic eruptions are a type of explosive eruption that results from magma erupting through water. The second phase of the Eyjafjallajökull eruption in 2010 was phreatomagmatic as a result of magma erupting under ice. Some submarine volcanoes are phreatomagmatic if the magma is gas-rich, for example Surtsey in Iceland.

Eruptions can range from a gentle gurgle to a violent, deadly burst. Terminology and Definition Eruptions occur when pressure inside the volcano increases, causing its molten liquid rock to shift and release its energy. Technically speaking, “quiet” eruptions are known as effusive eruptions.
Explosive volcanism | AMNH
Most explosive eruptions occur in volcanoes above subduction zones, where one tectonic plate dives beneath the other. Eighty to 120 kilometers below the surface, magma forms when the rocks of the mantle melt just above the subducting plate. The magma rises through the mantle, and erupts to form great composite volcanoes such as Vesuvius. Explosive eruptions have also built arc-shaped island …

Types of Volcanic Eruptions – Geology
The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth’s surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent. In explosive eruptions, the fragmented rock may be accompanied …

Now, a new study suggests that catastrophic supervolcano eruption – one that would result in a global death toll – is much more likely than previously believed. The research adds that there are around 20 such volcanoes that scientists had believed to be semi-dormant but which may in fact pose an extreme risk.

How Do Volcanoes Erupt? | U.S. Geological Survey
Magma that has erupted is called lava. Some volcanic eruptions are explosive and others are not. The explosivity of an eruption depends on the composition of the magma. If magma is thin and runny, gases can escape easily from it. When this type of magma erupts, it flows out of the volcano. A good example is the eruptions at Hawaii’s volcanoes …

If the viscosity is high, but the gas content is low, then the lava will pile up over the vent to produce a lava dome or volcanic dome. Explosive Eruptions. Explosive eruptions are favored by high gas content & high viscosity magmas (andesitic to rhyolitic magmas). The explosive bursting of bubbles fragments the magma into clots of liquid that …
Explosive Eruptions at Kilauea Volcano, Hawai’i? – USGS

Recent work by HVO and Smithsonian Institution scientists has discovered evidence of an explosive eruption that occurred on Kilauea’s eastern flank …
Volcanic Eruptions – Volcanoes, Craters & Lava Flows (U.S. National …
The rate of eruption can also influence how explosive an eruption is. If magma ascends slowly from deep within the crust, it is possible for the dissolved gases to escape nonviolently over time. But when magma ascension and eruption rate is rapid, the dissolved gases must escape all at once and the eruption is more explosive.
