Evaluate the strategies used to reduce the impact of tectonic hazards. Tectonic hazards are comprised of earthquakes and volcanoes; they are named ‘tectonic hazards’ as it is ultimately the movement of tectonic plates that cause these events. These hazards have the potential to kill thousands and devastate the region it strikes. Although the main hazard causes destruction‚ events that follow can be equally‚ if not more‚ devastating‚ for example an earthquake can often trigger a tsunami. Many strategies

US. Earthquakes California lies on a conservative plate boundary where the Pacific plate and the North American plate are the components. There are separated by a transform fault‚ known as the San Andreas Fault. The Pacific plate is moving north comparative to the North American plate however the fault is not smooth and so friction between the plates occur causing plates to lock. The continued pressure created by the movement of the plates around these locked portions of the fault causes the crust

San Andreas Fault is located California and it sits between the North American (East side) and Pacific Ocean (West side) lithospheric plates. California is commonly recognized as being a major part of the Circum-pacific Belt or what some may call‚ “Ring of Fire.” The Circum-Pacific Belt is shaped like a “horseshoe” of lively seismic energy. Earthquakes‚ tectonic plate boundaries‚ and volcanoes are stationed along this belt-line. The San Andreas Fault was created because of the strike and slipping motions

There is a thrust fault which is linked with the plate boundary between the Pacific and Australian plates which meets in the centre of South Island. The epicentre was 6 miles South East of Christchurch and the focus was very shallow at 3.1 miles. The earthquake is related to the pressure exerted between the two great plates‚ of which the Alpine

off the North East Coast of Japans main island Honshu. Why? Japan is located on the eastern edge of the Eurasian Plate. The Pacific Plate‚ which is an oceanic plate‚ subducts the Eurasian plate‚ which is a continental plate‚ to the east of Japan. This type of plate margin is known as a destructive plate margin. The process of subduction is not smooth. Friction causes the Pacific Plate to stick. Pressure builds and is released as an earthquake. So what? The earthquake occurred at a relatively shallow

Continental drift is a theory stating that the Earth’s continents have been joined together and have moved away from each other at different times in the Earth’s history. The theory was first proposed by Alfred Wegener in 1912. Whilst his general idea of continental movement eventually became widely accepted‚ his explanation for the mechanism of the movement has been supplanted by the theory of plant tectonics. However there was a problem in accepting this idea originally because Wegener had no convincing

Kobe lies close to a fault line between the Philippine and South Japan Tectonic plate. The 2 plates are sliding past each other. This is called a passive plate boundary. There is a direct relationship between plate margins and earthquakes‚ throughout the world. Japan is very prone to earthquakes‚ because of the countries special physical

The morphologically distinct bacterial isolates showing clear zones around their colonies due to decolorization of dye were selected for further studies. These isolates were screened for their ability to decolorize CV in MSM-CV dye amended agar plates. The screening procedure in agar plate was continued till the complete decolorization was obtained at different concentrations of CV dye. The
