Historical accounts of what is now known as the volcanic eruptions on the Greek island of Santorini‚ previously known as Thera‚ suggest that the estimated 1600 BC eruptions may be one of the most catastrophic natural disasters in human history.1 Conflicting beliefs of the timing of the event have been made. The debate of the traditional 1500 BC‚ and the earlier date emanate from the finding of an olive branch buried beneath lava‚ which radiocarbon dating has estimates is from 1627-1600 BC.2 The event

Thera‚ the volcanic caldera in Greece that violently erupted 3500 years ago spawning the myth of Atlantis‚ and wiping out most of the Minoan civilization‚ is deforming. Scientists suggest that this caldera‚ a crater-like volcano that has collapsed in the past‚ may erupt again‚ making the people of the island vulnerable. The deformation could cause many disasters such as tsunamis‚ earthquakes‚ and obviously eruptions. Scientists argue whether the volcanic caldera unrest is actually a threat to the

Why are earthquake impacts different in LEDCs and MEDCs? Any disaster either caused by humans or Mother Nature will make an impact but this depends where it hits. Obviously‚ if a disaster‚ or an earthquake in this case occurs somewhere densely populated rather an isolated area it will have a greater impact as life could be lost‚ buildings destroyed and as a result‚ high prices to pay. We will be looking at the impacts of earthquakes in Lower Economically Developed Countries and More Economically

over 20 active volcanos left in the world today. Have you ever wondered or learned about what causes a volcano? Volcanic eruptions can be a huge deal for the environment and the people around it. What causes do volcanos have on the environment and what cause does it have on the people? Well the truth is‚ the causes of active volcanos there are today‚ do have effects on its surroundings. What is a volcano‚ and what causes it to erupt? Volcanoes occur at weak points in the Earth ’s crust. The outer layer

of Volcanic Eruptions on Climate Introduction Recently there has been a lot of research in the field of climate change‚ and much of it is focused on anthropogenic affects on climate. However‚ there has also been a great deal of research focused on natural Earth processes and how they affect the climate (Robock 2000). One natural process which significantly impacts climate is volcanic eruptions. Volcanic eruptions affect the climate of the earth in many ways (Zielinski et al 1997). Volcanic ash

Undara Lava tubes consist of a lava field remaining from a massive volcanic eruption of Mt Undara which occurred 190‚000 years ago. During the Cenozoic‚ there was wide spread igneous activity in Eastern Australia. Volcanism commenced in the late Cretaceous (approximately 70 Ma) and continued through the Cenozoic. The cenozoic is the current geological era. It began 66 million years ago and continues today. About 23.3 km³ of lava flowed from the Mt Undara volcano at an estimated rate of 1000 m³ a

Effects of Volcanic Eruptions Alyssa Iferenta A volcano is an opening in the earth’s crust were magma from deep inside the earth forces its way to the surface. Once the volcano erupts the magma is called lava. Volcanic eruptions have positive and negative effects. For example the lava flow can cause complete chaocs and dismantle villages‚ but once the lava decompses it create extermely fertile soil. Volcanic eruptions throughout history have been known to cause mass destruction from lahars. [Refer
