Pelean
The most violent type of volcanic eruption is were the volcano lies on a Destructive Subduction Zone. Here the magma is viscous, thick and gloopy and there are high concentrates of Silica and Carbon Dioxide meaning a pyroclastic flow will occur and it will be very dangerous.
The most violent volcanic eruption is produced by a boiler volcano. In a boiler volcano, water is trapped in porous rock that is being heated by the magma, to the point that the pressure of the boiling water will at some point cause a huge explosion. The famous Krakatoa eruption was of this type.

The most violent volcanic explosions are usually generated from composite volcanoes and andesitic lava flows. These types of eruptions can throw lava and other debris several miles into the atmosphere.
When eruption types are arranged from most destructive to least, it is in descending order.

Another popular theory holds that the Thera eruption is the source of the legend of Atlantis. It is the most active volcanic centre in the South Aegean Volcanic Arc, though what remains today is chiefly a water-filled caldera. The volcanic arc is approximately 500 km (310 mi) long and 20 to 40 km (12 to 25 mi) wide.
A number of reasons. There are far fewer major volcanic eruptions than there are earthquakes. Earthquakes have no warning. Most volcanos give warning signs before a major eruption. Earthquakes affect far larger areas, and those areas are more likely to have people living in them. Unless you are near a volcano, *and* in the path of a pyroclastic flow, a blast, or are two stupid to get out of the way of a lava flow, they are unlikely to kill you.

Only the most violent volcanic eruptions feature a pyroclastic flow.
The eruption of Mount Mazama that formed Crater Lake was a caldera forming eruption. This is the most violent type of volcanic eruption.
Which of these volcanic eruption types is the least violent? B. Hawaiian A. Pelean B. Hawaiian C. Strombolian D. Plinian
Both the Pelean and Plinian eruptions are violent, and the Plinian (such as Vesuvius) are the most spectacular type. More specifically, there is a designation "ultra-Plinian" to describe highly explosive eruptions such as Kratatoa. The type of eruption that is most violent is when lava, ash and other materials are hurled into the air.
Pyroclastic material would be produced by a violent eruption of a volcano. Pyroclasts are gases in highly viscous magma which expand as they explode pulverized rock up through the vent.
No. The west coast is the most likely place for a volcanic eruption.
The most likely combination to result in a violent volcanic eruption is the presence of highly viscous magma (such as rhyolitic or andesitic magma) and a large amount of dissolved gas (particularly water vapor and carbon dioxide). These conditions can lead to a buildup of pressure within the magma chamber, causing a violent and explosive eruption. Other factors such as the presence of a vent or conduit for the magma to reach the surface and the structural weakness or faults in the volcano can also contribute to the severity of the eruption.
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.
