By:Caitlyn,Sayeh, and Petra


Mt.K.jpgMt Krakatau is located in Sunda Strait,Indonesia. It has a hieght of 813 m (2,667 feet). Mt Krakatau is a Stratovolcano. It last erupted in 2008. This island is still active. Since the 1950's the island has grown 13 cm each week. Scientist have warned people to stay at least 3 km away from the island.

The 1883 eruption (Or as some people say: The day the world exploded.)
The Eruption on August 27th 1883 ejected more than 25 cubic kilometres of rock, ash, and pumice. It created generated the loudest sound historically reported. The explosion was distinctly heard as far away as Perth in Australia aprox. 1,930 miles (3,110 km.) and the island of Rodrigues near Mauritius aprox. 3,000 miles (5,000 km.). 165 villages were destroyed and 132 seriously damaged. At least 36,417 people died and many thousand were injured from the eruption, mostly from the tsunami that came right after the explosion. The tsunami waves were about 120 feet high. The eruption destroyed two thirds of the island of Krakatoa. Eruptions sinces 1927 have built an intire new island called Anak Krakatau.

Effects

The combined effects of the pyroclastic flow and the tsunami had desasturious results in the region. There was no survivors of the 3,000 people that lived in Sebesi 13 km away from Krakatoa. Pyroclastic flow killed 1,000 people in Ketimbang on the coast of Sumatra 40 km away from Krakatoa. Teluk and Ketimbang in Sumatra were completely destroyed in the 1883 eruption.

this island is 200 meters above sea level. the original island of Krakatoa was 2,000 meters above sea level and had a radius of 9 km.

how to make a volcano

Ingredients:

-small drink bottle
-60 ml water
-1 tablespoon baking soda
-1/4 cup vinegar
-orange/red food colouring
-few drops of detergent
-small square of tissue.

Making the eruption:

Place the water, soap, food colouring and vinegar in the drink bottle. Wrap the baking soda in the tissue and drop into the bottle. The volcano model will then erupt.


For extra realism:

The volcano can be made more realistic by enclosing the structure in home made play dough. Mix 6 cups of flour, 2 cups of salt, 4 tablespoons of cooking oil, and 2 cups of water in a large bowl.

Mix the ingredients by hand until smooth and firm. Build up the mixture around the drink bottle to create the mountain. Lava channels and vegetation can be built around the volcano.
