Lava dome

Erta- Ale, is today the longest continually erupting volcano on the planet. It is pretty much a lake of lava that has been molten for over 100 years. These same volcanic forces are what created Ethiopia’s highlands. Seventy million years ago, Ethiopia’s land was just flat and deep terrestrial land. It wasn’t until molten lava rose from the Earth’s core and crated a huge dome of rock 500 miles wide: the roof of Africa. The summit is about three miles high and are home to some very…

Mount St. Helens is a volcanic stratovolcano still actively located in the Cascade Range in Western North America in the state of Washington. It was formed by a subduction plate boundary also located on the Juan de Fuca plate. The Cascade range is one of the most famous mountain ranges, and has one of the most active volcanos located in Western North America. Other areas or famous landmarks surrounding Mount St. Helens are the South Fork Toutle River, North Fork Toutle River, Castel lake,…

Pacific Ocean. Mount St. Helen's was created when the oceanic Jean de Fuca plate subducted beneath the North American Plate and has a long history of eruptive periods followed lengthy dormancies. Her volcanic activity was marked by thousands of years of lava and pyroclastic flows only to fall silent and then reawaken to begin her destructive cycle again. In the 1800's, Louwala-Clough fell silent, all signs of volcanic activity blanketed beneath her snow capped peak for over one hundred years…

000 people had been evacuated from surrounding areas. On June 5th, more evacuations began to take place with a level 3 alert issued, meaning a possibility of a major eruption. By June 9th, a level 5 alert had been issued with the extrusion of a lava dome. This meant that there was an eruption in progress. 25,000 people were evacuated in an area of 20 km from the mountain. At the time of the eruption, 58,000 people had been evacuated from an area of 30 km from the…

Monolithic dome is the safest and friendliest building to the environment because it is energy efficient and also because it is easily maintained. The dome owner will save an energy such as 50% charges compared to conventional building. The efficient of materials used in the construction of the building has mot negative impact on the environment because these domes need small place use the less materials which is generally 50% to 75% lees…

eruption of the volcano Mount Vesuvius began to cause a catastrophic damage that we still talk about today. It happened in the town of Pompeii. An estimated 20,000 people died that day. They died the most horrible death. Very few people escaped the red lava and gassy fumes. How did this come to be on this day? Were there any warnings? What would happen if Mount Vesuvius erupted today? Where is Mount Vesuvius located? Mount Vesuvius is located on Italy’s west coast. The Volcano overlooks the bay…

active volcanoes in Hawaii can be a threat to the island and to the people. It is important to discuss why do people enjoy living in Hawaii, knowing that there is a high probability of danger if one of the volcanoes’ erupts dramatically. How is Volcanic lava events after eruptions have an impact on the ecosystem and human settlement near an active volcano. The…

4.2.5. The Fantale geothermal prospect area The Fantale geothermal prospect is characterized by recent summit felsic lava, caldera collapse, extrusions in the caldera bottom and widespread fumarolic activity, signifying thereby the existence of a shallow magma chamber (Tekelemariam and Beyene, 2005). Active tensional tectonics form fissures up to 2m near the volcanic complex. From the area ground water discharge to the system is guaranteed by the proximity of the area to the western escarpment.…

2.2.3 Definition of Chelating Ligand EDTA From the above discussion, it can be concluded that chelating ligand EDTA is a process of reversible bond formation of a ligand that serves as chelating ( chelting agent or Chelator) that exist within the compound of EDTA. Basically, EDTA combines with some specific ion, so it causes the functions of EDTA as chelator. When the functions of EDTA as chelator, EDTA is a liquid ( solution) 2.3 Volcanic Ash Volcanic ash or sand is volcanic material debris…

people were buried and lost until the discovery made in 1738. This city is known as the lost city of Pompeii. Mount Vesuvius is a stratovolcano that consists alternate layers of ash and lava. Stratovolcanos have two types of eruption, one type where it produces mostly ash and cinders, second type where it produces lava. Mount Vesuvius is said to be a hundred of thousands years old. The volcano has a record of 50 over eruptions, with its most significant eruption in 79 CE. The city of…
