Yellowstone Supervolcano

Formation of a Supervolcano

The Caldera left behind... Paris would just about fit inside here.

Supervolcanoes: What do you know? Discuss/Predict what you think a super eruption would be like.... – How far do you think it would travel? – How large? – How many people could be killed? – What other effects would it have? – Why would it be so life changing? Intro...Intro... Fill out the Prediction Sheet

How Large? What do YOU predict? How far would it travel? How many people could be killed? Why would it be life changing? What other effects would it have?

Toba – the last supervolcanic eruption... The last super-eruption plunged the world into a freezing, volcanic winter that lasted a decade, and threatened the human population with extinction. While ordinary volcanoes can kill thousands of people and destroy entire cities, it's thought a supervolcano could claim at least 1 billion lives and devastate continents.

To Do… You will create a FEMA action plan using the hand-out How to start.. Use the evidence board as a starting point for your research You will create a plan for the planet that will include where survivors should live, how they will support themselves, and what their lives might be like You will also brainstorm possible solutions to problems that may arise while implementing the plan The world population is currently 7.3 Billion The population of the United States is 320 Million

Just in….Latest Updates…. 90% of the people killed within 1000km Direct eruption likely to cover ¾ of the North America Most of sunlight reduced in northern hemisphere & triggered rainfall in Africa Most deaths by inhaled ash turning to cement East coast of USA has 1 cm depth of ash Communication links disrupted all over USA, Europe and parts of East Asia 30cm can crush a roof – potentially 10 times this amount in certain areas Killing crops & contaminating water supplies

Group Feedback Partner up with one other member from each of the other groups in the classroom to discuss what they would do. Fill out the supervolcanoes group feedback form
