Earthquakes are one of the most destructive natural disasters. It is when the stored energy beneath the Earth’s surface is discharged and shakes the ground. The impact of this event is one of the most traumatic ones because it can put long term effects on a large area. They are proven to be unpredictable but once it strikes‚ all in a few seconds‚ cities and towns are completely flattened. Continue on to discover more about this dangerous calamity. Did you ever know that the earth can also move

An earthquake (also known as a quake‚ tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity‚ seismism or seismic activity of an area refers to the frequency‚ type and size of earthquakes experienced over a period of time. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. The sides of a fault move past each other smoothly

Thesis: Earthquakes have been a natural part of Earth for many years and are caused by a shift in the Earth’s tectonic plates. Tectonic plates shift when two separated pieces of Earth’s crust push together because of the pressure of the hot air below them pushing up on the plates from the heat of the Earth’s core. This pressure must be released somehow‚ so when the pressure becomes too great for the plates to withstand‚ one part of a plate gives way to the pressure by rising above the other part

Earthquakes are one of the most destructive of natural hazards. Earthquake occurs due to sudden transient motion of the ground as a result of release of elastic energy in a matter of few seconds. The impact of the event is most traumatic because it affects large area‚ occurs all on a sudden and unpredictable. They can cause large scale loss of life and property and disrupts essential services such as water supply‚ sewerage systems‚ communication and power‚ transport etc. They not only destroy villages

EARTHQUAKES o Plates sliding pass each other create friction o Friction builds up creating stress (a force) o Force is greater than plate can withstand‚ budges and breaks‚ creating earthquakes o Release a lot of energy KEY TERMS Seismology- the study of earthquakes and their effects Seismometer/ Seismograph - equipment measuring the amount of ground motion caused by an earthquake ***Let’s do a demo*** Seismogram- record of ground motion produced

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

The Military’s Pandora’s Box by Dr. Nick Begich and Jeane Manning This article was prepared to provide a summary of the contents of a book written in 1995 which describes an entirely new class of weapons. The weapons and their effects are described in the following pages. The United States Navy and Air Force have joined with the University of Alaska‚ Fairbanks‚ to build a prototype for a ground based "Star Wars" weapon system located in the remote bush country of Alaska.
