To what extent to you agree with the view that the hazards resulting from earthquakes and volcanic activity cannot be managed but merely adapted to. Earthquakes and volcanic activity are both nature disasters that human can’t control when or where it will happen and it may cause lots of death and economic loss. There is no way that we can stop it from being happened but we can definitely try to adapt it by many different ways. Firstly, volcanoes are found at destructive and constructive plate margins. At destructive plate margins, the oceanic plate goes under the continental plate due to it’s more dense, which is a process known as subduction.
Scientists have since seen these patterns as precursory to eruptions at many other volcanoes, including the 2004-2008 eruption of Mount St. Helens. At Mount St. Helens the value of an extensive system of seismic sensors has greatly improved our ability to determine the location and depth of earthquakes, and our ability to understand the physics of magma systems underground. The lack of short-term seismic or other geophysical indications in the hours and days prior to the May 18, 1980, debris avalanche, as well as prior to many short discrete explosions both before and after May 18, underscores that fact that scientists and public officials will not always have warning sufficient to issue short-term predictions of impending eruptive activity. Today, seismic
I will be discussing factors that cause differences in hazards posed by volcanoes. I believe the most important factor is the location of a volcano and the type of volcano. The most explosive and therefore dangerous volcanoes are found on destructive plate boundaries (Over 80% of the worlds volcanoes occur at these boundaries) for example the eruption of the Nevado del Ruiz in Colombia on the 13th November in 1985 which killed over 25000 residents of Arenas and Armero. At destructive plate margins, the oceanic crust is denser than continental crust and is therefore subducts under the continental crust. Due to high temperatures in the mantle of around 3000 degrees centigrade, this oceanic crusts melts and then rises due to the convection currents in the aesthenosphere .
Scanlan was recommended to Green by his state representative. There were several reports from Scanlan that the Centralia Mine No. 5 was highly explosive. (U.S. Mine Rescue Association, 2012) The reason the mine was highly explosive was because of the coal dust buildup.
Plate Tectonics Press Release Assignment Geology/101 An earthquake is the shaking of the ground cause by an abrupt shift of rock along a fracture in the Earth, called a fault. An earthquake is caused by the breaking and shifting of rock beneath the Earth’s surface. Ground shaking from earthquakes can collapse buildings and bridges; disrupt gas, electric, and phone services; and sometimes trigger landslides, avalanches, flash floods, fires, and huge, destructive ocean waves (tsunamis) (www.fema.gov/hazard/earthquake/facts). So the question that everyone wants to know is why does the planet move when the plates move? The planet moves whenever the two plates get tangled together.
Residents went to emergency shelters because of the radiation. Equipment failure, human error, and bad luck would conspire to create America’s worst nuclear accident. The impact of Three Mile Island was terrible, there was a massive cleanup. The cleanup started in August of 1979 and officially ended in December of 1993. The cleanup cost about 975 million dollars.
As a result of this, plants and animals are forced to adapt to significant changes that threaten their way of life. As explained by Suzuki in the article, every year at least twenty thousand species disappear forever and the rate of extinction is speeding up largely due to human activity. Many living things are now paying the price for all the man made pollution that has been created as a result of global warming. Furthermore we as a community do nothing to stop global warming and feel no sense of responsibility or duty to care for the overall well being of our world. Big businesses are releasing harmful chemicals into the atmosphere and oceans.
The gas is purposefully set on fire, leaving flames to spew far into the sky, burning for several days continually. This gas emits a very large amount of toxic gas. An article In the Miami Herald says "acute and chronic health problems can occur for those living near natural gas drilling sites." (BANERJEE) In conclusion, fracking can be very helpful to our economy. It can create jobs further down the line, reduce the carbon footprint of a company, and generate revenue for the towns around the dig sites.
If this effect essay were about a volcanic eruption again, the thesis statment might go something like: "The eruption caused many terrible things to happen; it destroyed homes, forests, and polluted the atmosphere." Exerpts/Graphics from English Works!, Gallaudet University, Washington, D.C.,2001 What steps should I follow to write a cause or effect essay? 1. After you have chosen your topic, write a thesis sentence. 2.
Japan is well known for being particularly amenable to subduction zone earthquakes, with huge pressures brought to bear by the sticking tectonic plate zones nearby it, and the slipping results in many earthquakes, some of them very big for instance the Tohoku earthquake. The Tohoku earthquake of March 11, 2011 also referred to as the Great East Japan Earthquake in Japan was one of the most powerful earthquakes that ever hit Japan and worldwide it’s recorded as the fifth most powerful earth quake. The earthquake triggered powerful tsunami waves that resulted into 15,883 deaths, 6,149injured and 2,652 people missing. The earthquake occurred in the north-western Pacific Ocean and lasted for approximately 6minutes. Initially, the earthquake was reported as having a 7.9magnitude (MW) and later it was raised to 8.8 then 8.9MW and finally to 9.0MW.
