http://volcanology.geol.ucsb.edu/soil.htm Structure: Kilauea is a shield volcano in the Hawaiian Islands and it is one of the most active volcanoes in the world. The Kilauea Volcano! Tour Guide The surface of the volcano is about 1500 km2

Kilauea has a large summit caldera (bowl-shaped) with a pit crater “Halema’uma’u Crater”

-mostly covered in flows of recent eruptions (1974) -one of Kilauea’s most active eruption centres. Eruptions: Eruptions usually happen in:

-the summit caldera
-the eastern rift
-the southwestern rift. Why: Type: Mt. Kilauea has “Hawaiian” eruptions.
considered the calmest

What happens?

lava comes out of fissures (linear cracks), or a central vent Lava: The Kilauea Volcano is one of the most active volcanoes in the world. It formed about 300,000 – 600,000 years, its oldest rocks are estimated to be 23,000 years old. Type: Kilauea has two types of lava

-‘A-‘a (stony/rough lava)
-Pahoehoe (smooth). How: It is a shield volcano Pahoehoe ‘A- ‘a
Kilauea’s lava flows burned down surrounding forests and volcanic ash distributed from the volcanoes eruptions destroy local plant life. Much of Kilauea’s body is underwater

The visible part of the volcano is a gentle slope The Environment Kilauea has two rift zones (cracks/splits that allow lava to erupt from the flank or side of the volcano)

-Southwestern consist of large lava flows down the volcano (quiet). Central vent eruptions Fissure-types have lava that spurt hundreds of feet Kilauea also affects the sea animals the live along the coast, especially the endangered hawksbill sea turtle because the lava flow can move towards the sea. The Atmosphere Rifts Kilauea can have dangerous effects on the atmosphere. For example, when Kilauea erupted in 1986 it released 2000 tons of sulfur dioxide daily which created massive air pollution. When sulfur dioxide is released it reacts chemically with sunlight, oxygen, dust particles, and water to for a mixture of sulfate aerosol, sulfuric acid, and more. Human Activity ECOLOGY Kilauea’s eruption has been continuous since 1983. The eruptions have caused lava flows which are about 35m thick and have covered about 123.2km2 of land which destroyed hundreds of structures and land. Soil Kilauea’s eruptions can create soil because when the lava flow is cooled to the point where it stops and cools over time things such as wind, rain, and water can break it down into new soil. of MT.KILAUEA fed magma from a pressurized chamber underground magma is pushed out of a vent or the caldera some geologists suggested that Mt. Mauna Loa has something to do with the eruptions Haaai, sit back and enjoy :} Is it a bird, is it a plane
.......it's supermannn, NO It' s................................... MT. KILAUEA By: Mathu, Brandon and Casey :) Buhbyeeeee ! Mathu's World Brandon's World Casey's World Doodle/editing credits go to Mathu Bibliography credit goes to Brandon Picture credit goes to Casey Kilauea's crater is 3,646 ft. deep, its circumference is 8 miles around and its wall of volcanic rock is 200 to 500 ft. tall. Kilauea's Past Eurptions: 1790 – A powerful explosion killed at least 80 people (mostly Hawaiian warriors and their families) due to an extremely fast flow of gas and ash. 1924 – A stream driven explosion killed 1 person. •1934 – 32nd U.S. president, Franklin D. Roosevelt visited Mount Kilauea in the summer and went to its crater, where he took some ohelo berries that belonged to a Hawaii legend. Coincidentally two months later after the visit, Kilauea erupted, which is odd because Kilauea does not frequently erupt. 1960 – A small town east of Kilauea, Kapoho, started to experience about 1000 small earthquakes on January 12th. On the 13th, during the night lava started to spill out of a sugar cane field above Kapoho. Most of the lava flowed out into the ocean, though a small branch pipe moved towards the town and buried it. Kapoho, Hawaii Safety Precautions for Tourist when visiting the volcano: Kilauea is a fairly mild erupting volcano. Tourist and visitors are allowed to walk on the cooled lava rock. Kilauea has not had any eruptions since 1983. Though it may not be as dangerous now, in 1959 there was an eruption that shot out 1,900 feet of magma. Safety Precautions for people that live near the volcano: Plan your escape route Have gas in your car Keep a battery-operated radio to stay up-to-date with the volcano eruption And most importantly: An emergency kit Your kit should include:: A battery-powered flashlight Oxygen mask(s) First-aid kit Goggles Optional: Food & water Can opener pacific tectonic plate moved
