2 Search for this.. Old Faithful – What is it? How does it work? Watch a YouTube video with sound on. Sulphur Caldron – Find a picture, study it carefully and tell me why you would not want to go for a dip (swim) in it.

3 Determine a conclusion on possible effects and responses of a super eruption Explain the difference between a supervolcano and a volcano Today we are learning to…. January 29, 2014

4 Reality?

6 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...

7 Locations... USA – Yellowstone,Wyoming; Long Valley, California; Longridge, Oregon Siberia, Russia Kyushu, Japan Toba, Sumatra, Indonesia New Zealand Even Ancient ones in Glencoe, Scotland & Scafell in Lake District!

9 Cause/Formation of a supervolcano... Yellowstone is caused by an underground HOTSPOT not plate margins...

10 Scale and Past Supervolcanic Eruptions

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

14 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.

17 Your Challenge... At the end of the lesson you need to explain your predictions of the effects in the world a year after the eruption. You must have: 1. An annotated world map showing where you think people will die, and where humanity could survive. It needs a key and detailed annotations of the possible effects of the Yellowstone super-eruption. Be as precise as possible using accurate figures for deaths and how countries have been affected. 2. An action plan for planet. Explain where you think survivors should live, how they will support themselves, and what form their lives would take. Consider jobs, housing, health, education, food as a starting point. 3. Possible problems that could prevent your plans from working. Think about Americas relationship with other countries, and the problems that a global community might face. Consider the effects of Migration, Food Shortage, Language Barriers, Culture Clashes and possible unrest/war. Yellowstone The world population is currently 6.4bn The size of the area affected could be 10 million times the size of Ground Zero in New York from 9/11 How to start.. Use the evidence board as a starting point for your research. Roughly annotate a world map to highlight affected areas. Research issues that you think would give you a detailed analysis of the effects of a super-eruption. You will need to know the population of different countries, but also you may need to link to agriculture, weather and climate and political issues.

18 The roles within the challenge… FEMA have asked for the following expert Geographers to work with them… Climatologist (British MET Office) Vulcanologist (Yellowstone Supervolcano Observatory) Aid Agency (Red Cross/Oxfam) You are working for United States Federal Emergency Management Agency (FEMA) to make plans to deal with the effect of a possible eruption at Yellowstone.

19 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
