Does a pyroclastic flow typically occur during a quiet or loud eruption?
Pyroclastic flow typically occurs during a violent eruption.
Does a pyroclastic flow typically occurs during an quite eruption?
No. A "quiet" eruption will produce lava flows. Pyroclastic flows generally result from explosive eruptions.
When does a pyroclastic flow happen after or before the eruption?
A pyroclastic flow typically happens during or after an eruption. It occurs when a volcano releases a fast-moving mixture of hot gas and volcanic materials, such as ash and rock fragments, that flow down the slopes of the volcano at high speeds. Pyroclastic flows are extremely dangerous and can cause significant destruction in their path.
Are pahoehoe and AA produced during explosive eruptions?
No, pahoehoe and aa lava are typically produced during non-explosive eruptions. Pahoehoe lava has a smooth, ropey texture, while aa lava is rough and jagged. Explosive eruptions typically produce ash, pyroclastic flows, and lava domes.
Was the eruption of Fuego gentle or explosive?
The eruption that occurs at fuego is explosive with lava flows
Does a pyroclastic flow typically occur during a quiet or loud eruption?
Pyroclastic flow typically occurs during a violent eruption.
Is it true that pyroclastic flow typically occurs during a quiet eruption?
No. Pyroclastic flows are characteristic of explosive eruptions.

Define violent eruption?
A violent eruption is a type of volcanic eruption characterized by explosive outbursts of magma, gases, and ash. This type of eruption often occurs when there is a high pressure buildup within the volcano, leading to the rapid release of energy. Violent eruptions can produce pyroclastic flows, ash clouds, and significant lava fountains, resulting in considerable destruction and hazards to nearby areas. Such eruptions are typically associated with stratovolcanoes and can have far-reaching impacts on the environment and human activities.
How are pyroclastic flows formed?
There are a number of ways in which pyroclastic flows occur and the first follows a Plinian eruption. If a fountain collapse of its eruption column occurs the jet is not able to heat the air sufficiently and lack of convection causes the plume to fall rather than shoot upward and flow down the mountain. The second is the same type of collapse after a vulcanian eruption in which a gas cloud is created that is denser than the air around it and this turns into a pyroclastic low. Other ways include a lava dome suffering a gravitational collapse, the mouth of a vent in a volcano frothing when the erupted lava degasses and when a section of a volcano collapses and a directional burst occurs.
What major rock does pumice belong to?
Pumice forms from the eruption of volcanoes. It occurs from hot pressurized rock that gets ejected from the volcano during eruption.
What event happens when a volcano occurs?
eruption
What is a eruption from the side of a volcanano?
An eruption from the side of a volcano, often referred to as a flank eruption, occurs when magma escapes through a fissure or vent on the side of the volcano rather than from the summit. This type of eruption can produce lava flows, ash, and pyroclastic material, potentially affecting areas adjacent to the volcano. Flank eruptions can be less explosive than summit eruptions but can still pose significant hazards to nearby communities and ecosystems. Such eruptions are commonly associated with shield volcanoes and stratovolcanoes.
Does lightning come after or during a volcanoes and explain?
Lighting occurs during volcanic eruptions. It is a result of electrical charges separating as particles of volcanic ash collide in an eruption plume.
