deposits made from the eruption. Where the rocks from the eruption were distributed and what their makeup are. A geochemist can also determine the chemical makeup of these deposits. By studying deposits and lava flows from past eruptions, it can assist in the prediction of where the lava will flow, how far the debris field will be and how far the ash will scatter in new eruptions. As retired volcanologist Robert Tilling so aptly described it, "the present is the key to the past – In a sense

island of Hawaii. Punaluu Black sand beaches started to form over hundreds or thousands of years. On Hawaii, there is a hot spot underneath it. There is a non-explosive volcano that spills out lava over thousands of years with hundreds of small eruptions each day. A cliff of black igneous rock formed where the lava meets the ocean. Then over many hundred of years, it is slowly eroded away by the big and small waves. When the waves start to erode away the rock on the cliff, it washes rock fragments and

Millions of years ago in Hawaii, a massive volcano erupted but no one knows how or why. One day in Hawaii, a 13 year old girl named Orabelle who loved the island, that was strong, went on a walk down by the beach being very angry with her parents, she goes on walks to cool herself down from being heated up. When she would go down to the beach, which was on occasions, she would pick up seashells and throw them into the ocean. Everytime she gets angry she makes the volcano erupt a little bit at a

Nevado Del Ruiz Eruption The Nevado Del Ruiz Volcano eruption was one of the most devastating events in the 20th century.The Nevado del Ruiz (located in Armero, Colombia) volcano eruption occurred on November 13, 1985. Armero, Colombia is located in the province of Tolima. The population at the time of the disaster was 31,000.The Volcano has erupted a couple times before the disaster one in 1595 it killed 636 people and another one in 1845 costing about 1,000 people lives.After the Nevado Del Ruiz

Popo is a composite cone volcano. Being a composite cone volcano, El Popo is characterized by a steep cone shape, which was created by many composite layers of material pouring out over numerous eruptions. The lava that comes out of El Popo is extremely viscous. The highly viscous lava does not travel very far, and typically cools down rapidly. Scientists believe that El Popo is about 730,000 years old. It has erupted more than 15 times since 1519. In 1994 El Popo produced gas and ash, which

countless outpourings of lava that advance great distances from a central summit vent or a group of vents. Extensive study of the Hawaiian Islands revealed that they are constructed of a myriad of thin basaltic lava flows averaging a few meters thick intermixed with relatively minor amounts of pyroclastic ejected material. During eruptions these outpourings help keep these volcanoes safe. When these volcanoes erupt lava fountains out form the volcano and is hot liquid lava is thrown into the air but

Mt.Etna is an active Stratovolcano which means that it is a shaped like a cone made of layers of lava, hardened ash, and other material erupted from the main volcanic vent. Also well known for a composite volcano. The formation of all stratovolcanoes takes place on boundaries between two tectonic plates where an oceanic plate is subducting into the mantle beneath the continental plate. In this case, the two plates involved are the Eurasian plate and the African plate. These types of volcanoes have

Americans across the country. It is also interesting to analyze and study volcanic eruptions that occurred in history in the past and are currently erupting in continents globally. Many people believe that the damage caused by volcanoes results only in the lava released from the crater. However, gases and tiny shards of glass prove to be more deadly, and they travel great distances through the atmosphere as gusts of wind propel them in all directions. In conclusion, volcanoes interest me the most out of all

The formation of LIPs associated with superplumes might have affected sea level, climate, and may have caused the extinction of some species. Because when volcanic eruptions begin, the huge quantities of basaltic lava spew out of the ground, the hot basaltic lava has low viscosity that can erupts the localities, and it can flow tens to hundreds of kilometers across the

now, after each of its eruptions, the cone size is reduced significantly. Every eruption forces pressure, heat, lava and ash out, widening the cone, while protruding lava builds it up and out. Volcanoes A volcano is a cone-shaped mountain with serious destructive capabilities. Volcanoes are created when magma from the Earth’s mantle comes up from the ground to the surface and spews lava which solidifies and over time, the volcano increases in size. Tectonic plates are the reason for this, as
