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.

Only the most violent volcanic eruption feature?
Only the most violent volcanic eruptions feature a pyroclastic flow.
What is common of most volcanoes that have the most violent eruptions?
They feature magma with very high silica content.
What is the most violent type of volcanic eruption?
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.
Do volcanoes have a scale magnitude?
Volcanoes don't, but volcanic eruptions do. Volcanic eruptions are rated by Colcanic Explosivity Index or VEI based on the volcume of material ejected. It ranges from VEI-0 for the non-explosive eruption of lava to VEI-8 for the most violent eruptions of supervolcanoes.
These volcanic eruption types is the least violent?
Which of these volcanic eruption types is the least violent? B. Hawaiian A. Pelean B. Hawaiian C. Strombolian D. Plinian

What is common of volcanos that have most violent eruptions?
They feature magma with very high silica content.
The most violent volcanic activity is associated with?
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.

What type of magma causes violent erpuptions?
Highly viscous felsic magma causes the most violent volcanic eruptions.
Do volcanoes have a scale magnitude?
Volcanoes don't, but volcanic eruptions do. Volcanic eruptions are rated by Colcanic Explosivity Index or VEI based on the volcume of material ejected. It ranges from VEI-0 for the non-explosive eruption of lava to VEI-8 for the most violent eruptions of supervolcanoes.
Which of the volcanic gases can help to destroy the ozone layer?
Volcanic gases also destroy ozone. Mt. Pinatubo was one of the most violent eruptions that caused ozone depletion.
These volcanic eruption types is the least violent?
Which of these volcanic eruption types is the least violent? B. Hawaiian A. Pelean B. Hawaiian C. Strombolian D. Plinian
What is the country that has the most volcanic eruptions?
Java and Bali
Do the most violent volcanoes spew mafic?
No. The most violent eruptions involve felsic magma.
What is the magma composition causes the most violent volcanic eruptions explain?
Felsic magmas produce the most violent reputations. This is because felsic magmas are the most viscous and thus can hold the most gasses. These trapped gases can expand explosively when they reach lower pressure near the surface.
