Eruptions are more violent because the more viscous lava solidifies more quickly and traps gases. Ashes and cinders are emitted when pressure is released. Dark, ash-laden clouds rise to form a cauliflower shape.

• Vulcanian

• Vesuvian

• Stromboan

• Plinean

A very violent explosion of gas, ash and pumice results in a narrower cloud that extends into the stratosphere. The high ash cloud from Mt Pinatubo’s 1991 eruption circulated the world several times in the stratosphere, causing a temporary global cooling of about 0.5°C

• Plinean

• Vesuvian

• Vulcanian

• Hawaiian

Highly viscous magma and a long period of inactivity cause an explosion out of a weakness in the side of the volcano, with a nuée ardente falling down the slope.

• Peléan
