story behind the legend of the Lost City of Atlantis (Whipps‚ 2008). As scientists piece together the evidence of past eruptions‚ they have found that products such as lava and ash have been produced by this volcano. Other eruptive products include basalt‚ rhyolite‚ amphiboles (Friedrich et. al 1998). Although many people visit the area of Santorini‚ they are always at risk because it is still an active volcano‚ but all that really remains today is a “water-filled caldera” (Friedrich et. al 1998)

Energy Source of Natural Hazards Disasters occur where and when the earth’s natural processes concentrate energy and then release it‚ killing and causing destruction. Four energy sources make the earth an active body: 1) the Earth’s internal energy; 2) solar energy; 3)gravity; 4)the impact of extraterrestrial bodies The interior of the Earth holds a tremendous store of heat released primarily from the ongoing decay of radioactive elements. Earth’s internal energy flows unceasingly toward the

was initially scoffed at‚ but when small initial efforts seemed to have an effect the scale of the operation was increased. Over seven months eight million cubic yards of sea water were pumped onto the lava flow; they cooled 5 million cubic yards of basalt lava to solid rock. The harbor and much of the town survived the eruption‚ likely as a result of the efforts to cool the lava. Iceland is known for its volcanic activity. A few years before Heimaey erupted; a nearby sub oceanic eruption formed

Introduction Metamorphism is defined as the mineralogical‚ chemical and structural adjustments in solid rocks to physical and chemical conditions which have been imposed due to changes in pressure and temperature or both. Metamorphism occurs below the surface zones of weathering and cementation. Conditions of metamorphism differ from the conditions under which the rocks in question were originally formed. Metamorphism produced as a result of the progressive increase in temperature and pressure‚

Welcome to the Galapagos Islands! The Galapagos are an archipelago of several volcanic islands located in the Pacific Ocean. The archipelago consists of 13 major islands‚ six minor islands‚ and 40 smaller rock formations and reefs spread out over 17‚000 square miles of ocean. They are born to create fire‚ and in the last 200 years a remarkable 50 plus eruptions have occurred. Looking into the geographic location and plate tectonic settings can easily help show why more than 50 eruptions have occurred
