Supervolcanoes are eruptions and explosions of catastrophic proportions, on the Volcano Explosivity Index VEI supervolcanoes are an 8 on a scale that runs from 1 to 8. Some of the effects are predicted to be:.
When it rots, it provides food for fungi and encourages wildlife. This offers protection under law to its large number of ancient trees, which support a vast variety of flora and fauna. Every year millions of visitors come to see the related features, such as geysers and hot springs. Global temperatures could drop by atudy — 5 degrees and remain low for many years.

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. Once Chances Peak had woken up it then remained active for five years.
Preserving the herd ibtesize fallow deer.
Cahora Bassa Dam – Case Study. The magma chamber under Yellowstone is currently 80km long, 40km wide and 8km deep so if and when an eruption occurs, the caldera that is left will cover roughly the same area as London. Over sfudy of years the pressure builds up and when the eruption eventually happens it drains the magma lake and the land above collapse down over, creating a caldera.
For this reason, they’re also known as stratovolcanoes. Local people were able to graze animals on it and collect wood for fires and building.
Each leap up the scale represents an increase of explosive scale of 10 times the power. Shield volcanoes are found on constructive plate marginswhere two plates move away from one another. Ecosystem destruction – Whole ecosystems would be destroyed. Shield volcanoes have the following characteristics: What are the likely effects of supervolcanoes? The Yellowstone Supervolcano – Case Studyy.
A supervolcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1, km3 cu mi. It’s a good example of sustainable management because it ensures a supply of wood for future generations. Food supply – Crops and food supplies would suffer hugely and prices would increase dramatically.
Supervolcanoes Case Study (Yellowstone)
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.
Death and destruction – Overpeople will be killed instantly due to the blast and pyroclastic event. Composite volcanoes are found on destructive plate marginswhere the oceanic crust sinks beneath the continental crust.
