PRESENTATION OUTLINE
KILUAEA VOLCANO
BY ABBEY AND ALYSSA
What is this natural disaster: A volcano is a type of mountain or hill that contains large blocks of lava, vapour and gas. It opens up the top and goes in downwards to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions will happen. Gases and rock shoot up through the opening and spill over with lava. There are four types of volcanoes, they are called a shield volcano, a composite volcano, a caldera volcano and volcanic hazards.

Who was involved: In 1989, the lava from the Kilauea Volcano destroyed the people in the Kalapana community. The Kilauea Volcano destroyed the national park visitor center. It produced enough lava to destroy 181 houses.

When was this event: The Kilauea Volcano began to form 300,000 to 600,000 years ago, it has been active ever since. It still remains active today. Mount Kilauea emerged from the sea 50,000-100,000 years ago.
In 1790 the Kilauea volcano exploded and killed at least 80 people. Mostly Hawaiian warriors and their families.
The most recent eruption was in January the 3rd, 1983 and continuing to be an active volcano.

Why/How does a volcano erupt: Volcanoes erupt because of the density and pressure. The lower density of the magma causes it to rise. It will rise to the surface and the weight of the rocks above it. As the magma rises, bubbles start to from the gas dissolved in the magma. The gas bubbles release pressure. This pressure helps to bring the magma to the surface and forces it in the air, sometimes to tremendous heights. Kilauea is one of the most active volcanoes in the world. The volcano rises 1,227 meters above the water level and is about 14 percent of the land area of the Big Island.

Where is the Kilauea volcano:
The Kilauea volcano is located along the Southern shore of the island. It is in Hawaii Volcanoes National Park, Hawaii island. It is 45 minutes south of Hilo. You can find the Kilauea Volcano on the Southern Eastern slope of Mauna Loa.

Interesting facts:
The Kilauea volcano is a shield volcano.
Kilauea is the largest but youngest volcano in Hawaii.
Kilauea was formed under a hot spot under the crust.
There have been 61 eruptions since it was formed.

House to withstand a volcano:
A concrete dome house, with a partial moat to guide a lava flow around and down the hill without contacting the house. The moat will have to be deep and wide enough to handle a heavy flow, with a high, thick concrete wall on the side toward the house, and be far enough from the house to keep the heat out. You would have a underground shelter that you can go in and reach contact from the inside of the house. The dome can Prevent the ash from staying on the roof. You would use concrete because it is the strongest material that will withstand a volcano and it won't melt or burn that easily.
The ways scientific understanding has developed to minimise the impact of the natural disaster have on our design house:
Put a moat around the house.
Make the roof round so the ash can fall off the sides.
Underground shelter in case of emergencies (massive explosion and about to erupt). Concrete dome so it won't melt or burn.

Moat with concrete wall. Underground shelter that you can access through the inside. Concrete door so heat doesn't go in. Moat far from the house.
Ladder to climb down to the underground shelter.
Concrete board to walk across the moat.

How to reduce volcano damage: Don't build towns nearby the volcano (even though The soil is fertile). Spraying oncoming lava with seawater helps. This prevention was found in 1983. If the bomb was shot at the correct place, the direction of the lava could divert. Block and penetrate the lava. A map that tells you where the lava goes through. You can tell exactly when the volcano will erupt by looking at the map. This will provide enough time to evacuate the people from danger.
We are like volcanoes, when pressure builds up, we explode -Alyssa & Abbey
