Does a pyroclastic flow typically occur during a quiet or loud eruption?
Pyroclastic flow typically occurs during a violent eruption.
What kind of eruption has an pyroclastic flow?
An explosive volcanic eruption. Pyroclastic flow is a mixture of fast flowing hot gases that travel down and away from the 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.
What are differences between an eruption column and pyroclastic flow?
An eruption column is a vertical column of ash and volcanic gases rising above a volcano during an explosive eruption, while a pyroclastic flow is a fast-moving avalanche of hot rock fragments and volcanic gases that flows down the sides of a volcano at high speed. Eruption columns are visible in the sky, while pyroclastic flows move rapidly along the ground, causing devastation in their path.
