Kilauea Volcano

Of the volcanoes that are located in the United States there are two which are world renowned for their activity and their power to change the region surrounding them. The two volcanoes would be Mount Saint Helens and Mount Kilauea. In order to get a better understanding of these volcanoes we will be comparing and contrasting them as well as talking about how they were formed and when they last had an eruption.

The gravitational stress on the volcano flanks develops large-scale on-shore and off-shore sliding, related to the activity of the rift zones. The M=7.2 earthquake at Kilauea on 1975 was probably related to strain accumulated throughout the south flank from dikes intruded in the rift zone (Swanson et al., 1976). However, the earthquake itself resulted from abrupt southward movement of the south flank across the underlying oceanic crust, activating the Hilina-Pali fault system. Such faulting not only provides a means for the flanks to adjust continuously to intrusions, but also generates the stress patterns needed to constrain future dikes to propagate along the rift axis. Therefore, rift intrusion and lateral spreading are major contributors

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

Kilauea is a volcano in the Hawaiian Islands it is one of the five shield volcanoes in the Hawaiian language Kilauea means spewing or spreading. Mt St. Helens is an active stratovolcano in Washington it is named after British diplomat lord st Helens.

Kilauea is one of the most active volcanoes on Earth, and it is the youngest. Kilauea stands just under 4,200 feet tall above sea level at its highest point.

The basic theory of plate tectonics says that all volcanic activity should occur between lithosphere plates (Physical Geology). However, the Hawaiian Islands bend this rule by being located directly in the middle of the Pacific plate. The Hawaiian volcanoes are known as intraplate volcanoes. This may not seem possible because it disrupts the rule of plate tectonics, but there’s the exception of a hot spot. T. Wilson suggested that the Pacific plate moved in the northwestward direction over a melting spot deep within the mantle, and this hot spot remained relatively stationary and supplied magma to the moving Pacific plate to form the Hawaiian Island chain (Volcanoes in the Sea). In order to prove this suggestion, the structure of the Hawaiian Islands must be in line with a hot spot origin. This will be

Mauna Kea is currently the tallest mountain in the Hawaiian Chain. 4,205 meters above sea level, Mauna Kea is located on the island of Hawaii. It is the second largest surface that comprises of the five volcanoes on Mauna Kea. With Mauna Kea being the largest Mountain in the Hawaiian chain, it is a popular location to look into the galaxies, to find the origin of life.

As the crust moves away from the volcanoes and cools and becomes less dense and breaks up.

Parmi:(In a normal Voice) - This is parmi shah from Hawaii news now. Breaking news the volcano Kilauea, an active shield volcano, has erupted. The booming lava exploded from kilauea waiting to burst. The lava has covered 37 square miles of existing terrane. Some areas have been mantled repeatedly and are now buried beneath 80 ft of lava. The volume of erupted lava is nearly 2 billion cubic yards--enough new rock to

Krakatoa is a volcano (Shocker), that is on the Indonesian Island Arc, near Java. It is famous mostly for its fatal eruption in August of 1883, which killed over 36,000 people. The volcanic activity was most likely caused because of an Indo-Australian plate that moves northward towards mainland Asia.

Authors, Fiske and Jackson collaborate to write a geological survey for the United States. Hawaii is made up of a collection of islands which contain many volcanoes, all at different stages ranging from Mid-tertiary volcanoes to Holocene volcanoes. Scientists have noticed a pattern in the Hawaiian volcanoes according to their geographical location. A significant portion of volcanic activity has taken along the volcanic rift, a linear zone along Hawaii. Fiske and Jackson provide insight about the volcanic rift, and how volcanic activity is not based on geography, but on stress fields within the volcanoes.

Waianae Volcano is one of the largest volcanoes on Oahu, an island in Hawaii. Todd, a professor of Geology from the University of Hawaii, and two other experts, Sinton and Pringle, collaborate to write about Waianae, and its postshield activity. The postshield activity including mass wasting, which is a geomorphic process in which rock or soil moves downslope. Presley, Todd, and Pringle conclude that there may be a correlation between mass wasting and Hawaiian volcano evolution.

Volcanos have a big history in the world. They have caused havoc and caused beauty for thousands of years. 20 volcanos are erupting at this very moment! The author said “Some 1300 (and perhaps more than 1500) have erupted in the Holocene (the past 10,000 years).” (Simkin 58). This means that there have been 1500 eruptions that could have caused double that amount of deaths in the last 10,000 years. It might have caused marvelous sights as well.

This is only a general overview of the inner workings of volcanoes and their eruptions. For more infomation, visit Volcano World -- The Premier Source of Volcano Info on the Web.

The term volcano can either mean the vent from which magma erupts to the surface, or it can refer to the landform created by the solidified lava and fragmental volcanic debris that accumulate near the vent. One could say, for example, that large lava flows are erupted from Kilauea volcano in Hawaii, the world volcano here
