The Juan De Fuca tectonic plate is found on the west coast of North America. It is next to the North American plate‚ and according to America’s Tectonics‚ the Juan de Fuca plate is getting subducted under it. This plate is made of oceanic crust‚ but it is also basaltic in some areas. It was named after the pilot and sailor‚ Juan de Fuca‚ an explorer from Europe in the 1600s. The Juan de Fuca plate has a divergent boundary in the Juan de Fuca ridge. New material is made by the Juan de Fuca ridge

Banff National Park is Canada’s oldest national park‚ established in 1885 in the Rocky Mountains. Banff is the third-oldest national park in the world. In 1883‚ three railway workers‚ Thomas McCardell‚ William McCardell and Frank McCabe discovered a number of hot springs (now known as cave and basin) at the base of what is now called Sulphur Mountain. The park started as a 25 square kilometers (10 square mile) reserve around the Sulphur Mountain Hot Springs‚ established by the Dominion of Canada

Volcanic eruptions can cause damage within hundreds of miles away. The volcano ash’s causes airplane engines to fail‚ destroys crops‚ contaminates water‚ and damages electronics and machinery. When the ash touch’s the ground‚ burying everything‚ sometimes even make’s buildings to collapse. Mount St. Helen’s produced more than 490 tons of ash that fell over some many miles. All volcanos are dangerous. They are all scattered all over the world and we don’t know when they are going to blow. The three

Geologic Setting The Wabigoon Subprovince is part of the Superior Province‚ an Archean age craton composed of E-NE trending granite-greenstone and metasedimentary terranes that span from western MN to northern Quebec. In Canada‚ the Neoarchean Wabigoon subprovince hosts numerous precious and base metal deposits‚ including the Sturgeon Lake VMS deposits and Rainy River and Hammond Reef gold deposits. Historically considered moderately to weakly prospective for hosting VMS deposits due to inferred

To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) A volcanic hazard is a situation that poses a threat to life‚ the environment‚ and infrastructure after a volcanic eruption. Volcanoes are formed at various plate boundaries‚ such as at mid oceanic ridges where plates are moving apart‚ for example at the Mid Atlantic ridge. They also occur on or near subduction zones. The ‘ring of fire’ tends to be where the most violent volcanic activity occurs.

The Yellowstone volcano has been a growing concern for many Americans over the years. Especially after the eruption of the Mount St. Helen’s volcano in the 80’s. Rumors of a catastrophic explosion have caught the attention of everyone from the media to newspapers who try to sell the fear of an imminent explosion and the extreme damage that could possibly happen. However‚ the truth is just the opposite. In actuality‚ these fears are almost always unfounded‚ and usually arise from the the rumors of

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

Precambrian time‚period of time that reaches out from around 4.6 billion years back to the start of the Cambrian Period‚ 541 million years prior. The Precambrian speaks to more than 80 percent of the aggregate geologic record. All life-structures were for quite some time expected to have begun in the Cambrian‚ and consequently all prior rocks were gathered together into the Precambrian. Albeit numerous fluctuated types of life developed and were safeguarded widely as fossil stays in Cambrian sedimentary
