They will eject at least 1,km 3 when they erupt compared to a normal volcano, which release around 1km 3 of ash and rock. There are two main types of volcano – composite and shield. For this reason, they’re also known as stratovolcanoes. Location Image courtesy of Wikipedia. It would spark climate change that might trigger a mini-ice age due to the amount of sulphur dioxide thrown into the atmosphere and reflecting solar radiation.

What are active, dormant and extinct volcanoes? There are two main types of volcano – composite and shield. Location Image courtesy of Wikipedia. They reshoot at this height, producing new wood for future cutting. Shield volcanoes are found on constructive plate margins , where two plates move away from one another.

Planning measures adopted include the following: Supervolcanoes are as their name suggests, super. It was the first National Park in the World and is a very volcanically active area due to the hotspot beneath it.

Each leap up the scale represents an increase of explosive scale of 10 times the power.

Calderas are formed when the magma chamber of a supervolcano collapses after an eruption leaving a large bowl shape in the ground. When it rots, it provides food for fungi and encourages wildlife. Unlike composite volcanoes, with their steep sides, they are difficult to spot.
