David Kelleher Geophysicists Discover Slippery Secret Of Weaker Underwater Earthquakes http://www.sciencedaily.com/videos/2007/ 1007-underwater_earthquakes.htm In December 2004‚ an underwater earthquake triggered a string of tsunamis along the Indian Ocean with devastating effects. Now‚ scientists have found ways nature is preventing some deep ocean earthquakes and save lives. Strong underwater earthquakes start off silent -- until their tsunami waves roar on shore‚ destroying property and

Did anyone know that around 10 volcanoes erupt everyday and it helps many people? Volcanoes are very good for many thing and it helps alot of people in the world for a huge list of things that it can do for people volcanoes can help economic trouble and even it can help hunger. This area where people live on volcanoes are safe on many levels like some volcanoes people live on are super quiet eruption volcanoes and they do not erupt and explode like volcanoes people think of. But sometimes disaster

In 2010‚ a huge earthquake hit Haiti and almost flattened the tiny country. A year later‚ in 2011‚ an equally huge if not bigger earthquake hit Japan. Many people were affected in Japan but now the country is running smoothly again while Haiti’s poverty rates are still as a high as 80%. Why did these earthquakes have such different effects on these countries? The most significant reason these earthquakes had such different effects is the simple matter that Japan is just much more prepared than

Types of Volcano Research Composite Volcanoes: Composite volcanoes‚ also called strato volcanoes‚ are formed by alternating layers of lava and rock fragments. This is the reason they are called composite. Strato-volcanoes often form impressive‚ snow-capped peaks which are often exceeding 2500m in height‚ 1000sq.km in surface‚ and 400km3 in volume. Between eruptions they are often so quiet they seem extinct. To witness the start of a great eruption requires luck or very careful

Volcanoes--sinister and dangerous creations that wreak havoc and death‚ demanding fear and reverence from all. But yet‚ people show none. They have busy lives and don’t have time for "silly" things such as destructive volcanic eruptions. On top of that‚ they have all seen the movies in which people have effortlessly escaped the wrath of magma flow of "the rather gentle and atypical volcanoes in Hawaii." These people willingly‚ and sometimes unknowingly‚ make themselves easy prey for volcanic eruptions

Shield volcanoes Main article: Shield volcano Shield volcanoes‚ so named for their broad‚ shield-like profiles‚ are formed by the eruption of low-viscosity lava that can flow a great distance from a vent‚ but not generally explode catastrophically. Since low-viscosity magma is typically low in silica‚ shield volcanoes are more common in oceanic than continental settings. The Hawaiian volcanic chain is a series of shield cones‚ and they are common in Iceland‚ as well. Lava domes Main article:

signifies a vent. Volcanoes are not the realm of any single scientific discipline. Rather they require study from many scientists from several specialties: Geophysicist and Geochemist to probe the deep roots of volcano; Geologist to decipher prehistoric volcanic activity; Biologist to learn how life became established and evolve in barren volcanic islands; and meteorologist to determine the effects of volcanic dust and gases on the atmosphere‚ weather and climate. Volcanoes affect humankind in
