Only Plinian and Pelean volcanic eruptions feature flow?
pyroclastic flow
Pyroclastic flow would most likely in a what eruption?
smoke weed
Only plinian and pelean volcanic eruptions features what flow?
Plinian and Pelean eruptions poth commonly produce pyroclastic flows. However, such flows can also occur with Vulcanian eruptions.
Only the most violent volcanic eruption feature?
Only the most violent volcanic eruptions feature a pyroclastic flow.
What do only the most violent volcanic eruptions feature?
The most violent volcanic eruptions are found in destructive/convergent plate boundaries. 80% of the world's active volcanoes are found occur along destructive boundaries. Acid-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption.

Do all volcanic eruptions feature rivers of lava?
No. Rivers of lava are characteristic of non-explosive (Hawaiian) or mildly explosive (Strombolian) eruptions. Volcanoes can erupt in a number of manners. Vulcanian eruptions produce clouds of ash and eject large chunks of rock called volcanic blocks. They sometimes feature a noticeable shockwave. Pyroclastic flows may sometimes occur. Peléan eruptions produce massive clouds of material, primarily in the form of pyroclastic flows, the deadliest hazard produced by volcanoes. These flows are avalanche-like masses of superheated ash, rock, and gas that race down the sides of a volcano. Plinian eruptions are the most violent. They are noted for producing vertical columns of ash that tower miles into the sky. These columns eventually spread out and rain ash on the surrounding countryside. Plinian eruptions often produce pyroclastic flows. In the largest events, termed Ultra Plinian, these flows may dwarf those of Peléan eruptions. Phreatic eruptions occur when groundwater comes in contact with magma or hot rocks and flashes to steam. Clouds of ash often result, formed from rock blasted by steam explosions rather than from fresh magma. Submarine eruptions occur when lava is erupted underwater. The surface of the lava cools so quickly that it only flows a short distance before crusting over. It then breaks through this crust and repeats the process. This creates a series of lobes in a type of formation called pillow lava. Surtseyan eruptions occur when molten rock erupts in shallow water. Steam explosions result, producing fountains of ash, rock, water, and steam. Dome-building eruptions occur when a volcano erupts dacite or rhyolite lava. These sorts of lava are so viscous that often they do not flow away from the vent, but rather pile up into a rocky dome. In some cases a dome may collapse, producing pyroclastic flows.
What type of lava flow does mount meakan have?
it has pyroclastic flow and has small eruptions of ash.
Where is pavlof volcano?
On the tail of alaska. this is one of the longest and stongest eruptions of lava flow in the history of eruptions.... did you know that?!?
What is a Pelean volcano?
The most important characteristic of a Pelean eruption is the presence of a glowing avalanche of hot volcanic ash - or a pyoclastic flow. Gas, dust and lava fragments are blown out of a volcano's central crater. This travels down the side of the volcano at speeds in excess of 150 kilometers per hour
What are the two different types of volcanic eruptions?
Flow, and explosive
