Magma

A giant is born from the depths of the ocean, a catastrophe waiting to happen. As hot magma bubbles up from the depths of the earth, it pushes through the surface and Krakatoa is born. The 1883 eruption of Krakatoa was devastating. The resulting toxic gases, deadly pyroclastic flows, and giant tsunamis are astonishing. The eruption of Krakatoa was the loudest eruption ever heard in history. Krakatoa is located in the Sunda Strait between Java and Sumatra in Indonesia. The island of Krakatoa is…

They both relate because they both occur when tectonic plates move. When a volcano is in their active stage of life it will experience seismic anomalies being caused by the movement of magma within the chamber, then when the rocks are really hot and earthquake will arise. Earthquakes and Volcanoes occur when tectonic plates are moving. Tectonic plates are pieces of the earths crust and upper mantle. Earthquakes are cause when the rock underneath us suddenly breaks along a fault. The release of…

Mt. Fuji is a Basaltic Stratovolcano. This volcano was “Born” from the base of Mt. Komitake about 100,000 years ago. The volcano that is today was formed over 2 generations of volcanic activity turning the “old” Mt. Fuji into the “new” Mt. Fuji. In 1707 was has been the latest eruption, or at least until now. In the 1707 there was an Edo Period, is caused an explosive eruption that created the Hoei crater and volcanic ash formed a vast volcanic plane to the eastern side of the mountain. Since…

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…

valley running along the spine, and its known as an oceanic spreading center which is in charge of the seafloor spreading. New seafloor is being produced when convection currents rise in the mantle layer which is under the oceanic crust, it then create magma that cools down into basalt where two plates is push away from each other. Ridge push and slab pull are the two processes that is in charge of the spreading of the mid ocean ridges. The ‘ridge push’ process occur when the growing part of the…

On June 15, 1991, Mt. Pinatubo erupted. Volcanologists successfully predicted the eruption and issued a warning ahead of time, which allowed minimal casualties. The stakes for failing to predict an eruption accurately are high. If one fails to predict an eruption and it happens then lives and property can be lost; however, if one does predict and eruption and it does not happen then one’s personal reputation can be damaged or destroyed. In the case of Mt. Pinatubo, the U.S. volcanologists…

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. The…

Mount St. Helens By Kyle Lockhead Volcanoes destroy and volcanoes create. The catastrophic eruption of Mount St. Helens on May 18, 1980 was devastating. It shows the destructive power of a volcano. Yet, over a time span longer than human memory. Volcanoes have played a key role in forming and modifying the planet we live on. More than 80 percent of the Earth's surface is from a volcano and the eruption from Mt St. Helens is big part in the environment but the mountain of Mt St. Helens will never…

Dolerite is a hard igneous rock which played a prominent role in the surface geology and scenery of Teesdale. It formed 295 million years ago when magma oozed up through fractures in the earlier Carbon­iferous rocks, spreading out between the layers of limestone, sandstone and shale. The magma cooled and solidified into a massive sheet of igneous rock, reaching thicknesses of up to 230 feet (70m). Although the Whin Sill has suffered erosion and weathering spanning millions…

At about 9.30 on August 21, 1986, rumbling sounds lasting 15-20 seconds brought people out of their Cameroon homes in the small village of Nios. Not minutes after, a lethal gas cloud pooled out of nearby Lake Nyos and spread over the town. People reported smelling an odor like rotten eggs or gunpowder, felt a warm feeling, and quickly lost consciousness. Survivors, who woke 6-36 hours, felt disoriented and weak, and found that their friends and family were all dead. About a day later began the…
