Reseach Paper Circum-Pacific Belt And Mediternian Belt Group 3: Rena Mae Noserale Karen Joy Umadhay Loreen Sultan Circum-Pacific Belt of Fire The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements

eruption in 1968 Mount Etna has been constantly erupting every year. Though these eruptions are not always violent sometime volcanic bombs can be fired from the composite volcano and since its eruption in 1968 it has killed around 77 people, most of these unwitting tourists who did not take enough care. However due to the volcano being located in the fairly rich area of Sicily the impacts of its hazards have been managed and fairly efficiently. For example, explosives were first used to relocate the

Hazards will be an unfortunate result of a volcano. They are defined by their ability to effect any property and life that can be lost due to the hazard and halts and slows the productive sustainability of a population. Ultimately the physical effects of a volcano will define the hazards. In different places that the volcanoes occur there are different plate margins (Destructive and constructive) that will create different types of hazards. These hazards will include; lava flows, mudflows, pyroclastic

Krakatoa is a volcano island located in the Sunda Strait, and is apart of the Indonesian Island Arc. It is also on the Ring of Fire and sits between two islands, Java and Sumatra. Krakatoa’s 1883 eruption is known as one of the most deadly eruptions in history. This powerful and explosive eruption follows many of the same general events of a volcanic eruption. The start of this eruption happened deep inside the earth’s core. As I explained the inner core and outer core are extremely hot and cause

The Nevado del Ruiz is a volcano in Colombia. The volcano is located in the Andes volcanic chain on the andean volcanic belt. Nevado del Ruiz was formed by subduction on the nazca oceanic plate boundaries. Subduction is “a geologic process in which one edge of one crustal plate is forced below the edge of another.” The Nevado del Ruiz is known as an active stratovolcano. ”A stratovolcano is a tall, conical volcano composed of one layer of hardened lava, tephra, and volcanic ash.” Stratovolcanoes

erupting Indonesian volcano"- November 12, 2013- Channel News Asia More than 5,000 people have fled their homes in western Indonesia in recent days following a series of violent volcanic eruptions, an official said Tuesday. Mount Sinabung on the north of Sumatra island has been hurling out red-hot ash, rocks and torrents of glowing lava up to seven kilometres into the air since the start of the month. Villagers from the nearby Karo district are being evacuated as the volcano, which erupted in September

bigger threat to these socio-economic factors as a result of the eruption. Firstly, the type of volcano will also depend on the type of eruption and where abouts it lies within the plate boundaries. A hot spot however does not lie on a plate boundary but causes a volcano due to the high pressures of heat flow. An example of this is in Hawaii, southwest of the United States. Kilauea is a shield volcano on the southern part of the island which erupts runny, non-viscous lava and tends to be large in

Mega-Tsunamis: The Oceans Deadliest Weapon Every single minute of every passing hour, our oceans have the potential to cause catastrophic damage and disaster. With its vast beauty and bountiful resources, the wild ocean comes with a handful of rare geological time-bombs. Once unleashed, they can create an extravagant phenomenon. Gigantic mega-tsunami form, these giant waves are able to cross oceans and demolish cities and countries on the opposite side of the earth. Thanks to modern technology

visible signs recorded by observations and various instruments. An example is the tiltmeters which were successfully used in the prediction of six eruptions of Mt St Helens between June 1981 and August 1982. This allows volcanologists to predict when a volcano may erupt and thus set into action any evacuation plans. Mt St Helens also used gas and steam monitors by measuring carbon dioxide levels which gives evidence of magma rising to the surface; this can help to predict the material produced during an

natural occurrences that usually cause great amounts of damage. The most common of which are volcanoes, hurricanes, tornadoes, earthquakes, and tsunamis. The Mauna Kea Volcano is an ancient dormant volcano that last erupted 4500 years ago. It was one of the volcanoes that aided the creation of Hawaii. Mauna Kea is a dormant shield volcano in the "post-shield" stage. Underwater volcanoes started to build Mauna kea from the bottom of the sea around 0.8 million years ago. In the article, “Mauna Kea” it
