Krakatau

1. Krakatau By Rebecca Kane

2. Its located near the Indonesian island of Rakata in southwestern Indonesia. Near the straight of Java and Sumatra.

3. Indonesia Made up of multiple islands The climate is mostly tropical

4. Date Krakatau erupted on Aug. 27, 1883

5. 1886 Time Period The time period consisted of American Civil War, Assassination of President Lincoln, and the California Gold Rush

6. What Happened Before In May the Volcano started to have explosions The activity started to die down around June

7. Ash shot 6km (20,000ft) into the sky Explosions could be heard 99mi away

8. What Happened During It was rumbling for months until it finally erupted on Aug. 27, 1886 The island was 450km above sea level, but the eruption left it 250 below

9. Final explosion heard over 4500km away Half of the volcano slide into the ocean

10. What Happened After Magma flowed 40km and consumed ships in fire and ash Eruptions created tsunamis 40m high

11. Debreu shot into the sky leaving a ring around the equator Also creating hazes that bent the incoming light Final death was 36,417 people

12. Science behind volcanoes Why: Plate Techtonics The pates that are crashing into each other are creating higher temps

13. The heat gets so high it starts the melt the plates Certain vents on the ocean floor allow the magma to rise and start a volcano

14. What: Silica levels determine the vicious it will be and it controls the viscosity Temperature will also determine how vicious it will be (Hotter the less)

15. Viscosity is important because it will tell the type of eruption it will have and the type of volcano Higher viscosities tend to make higher/steeper volcanoes

16. Where: forms in belts or chains location of volcanoes splits in 3 groups

17. 1.) Rift Volcanoes- forms when the plates are moving away from each other 2.) Subduction Volcanoes- when plates collide and slide over each other 3.) Hot Spot Volcanoes- form along where plates meet.
