This statement is incorrect. Plinian and Pelean eruptions are types of explosive volcanic eruptions that do not typically produce lava flows. Instead, they involve the violent ejection of ash, rock fragments, and gases into the atmosphere. Lava flows are more commonly associated with effusive eruptions, such as those of Hawaiian volcanoes.
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
Pelean eruptions are most commonly seen at stratovolcanoes, which can also be called composite volcanoes.
Pelean volcanic eruptions feature pyroclastic flows, which are fast-moving currents of hot gas, ash, and volcanic rock fragments. Plinian eruptions also produce pyroclastic flows, but they are characterized by massive vertical columns of ash and gas rising high into the atmosphere.
Yes, there is a difference between lava and lava flow. Lava is the molten rock beneath the Earth's surface, while lava flow refers to the movement of lava as it travels down a volcano or hillside. Lava flow is the result of the eruption of molten rock, which can vary in speed and direction.

A pyroclastic eruption, involving a viscous magma, typically of rhyolitic or andesitic type. An ignimbrite is the deposit of a pyroclastic density current, or pyroclastic flow.
Pelean can have two meanings. In Spanish it translates as "they fight." Pelean is also a kind of volcanic eruption that features large avalanches of superheated ash, rock, and gas called pyroclastic flows.

When eruption types are arranged from most destructive to least, it is in descending order.
Pelean volcanic eruptions feature pyroclastic flows, which are fast-moving currents of hot gas, ash, and volcanic rock fragments. Plinian eruptions also produce pyroclastic flows, but they are characterized by massive vertical columns of ash and gas rising high into the atmosphere.

Yes, there is a difference between lava and lava flow. Lava is the molten rock beneath the Earth's surface, while lava flow refers to the movement of lava as it travels down a volcano or hillside. Lava flow is the result of the eruption of molten rock, which can vary in speed and direction.
