Figure 5.19 The mortar in unreinforced masonry walls such as these in Iran‚1990(A) can easily fail during an earthquake. Oftentimes the entire structure crumbles‚ leaving a pile of rubble in which survive. Shown in(B) is one of the many masonry homes to collapse during the 1988 Armenia earthquake (M6.9)‚ claiming nearly 25‚000 lives. The failure is called soft-story collapse. Soft-story collapse is a common problem in commercial building where the first floor has considerable open space for

Why they die? The question most asked by the families and survivors of the USS Indianapolis. The sinking of the ship was one of the worst day in history for the navy. 880 men died during the sinking of the ship and only 317 survived. There is several reasons why those 880 men died. One of the major reasons those 880 men died was because of different diseases they suffer during the four days in the ocean. During the sinking of the ship men were injured severely and that cause the death of some of

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

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

their arm blown off from the mill factories they work in‚ and often times‚ people die because everything is so terrible. Some people say that you can still hear the wails of others from the abandoned ones. Where there are factories‚ there is pollution. The sky is terribly polluted and the air hard to breathe‚ but so is the air everywhere else. People are not allowed to go outside because then they would probably die from the acid rain that often talls or see how the land around them is dying. All

Definition: An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves.TThe recent earthquake In India on September 18 ‚ 2011 compelled me to write an essay about earthquake. In this essay many things related to earthquake will be discussed.e seismicity or seismic activity of an area refers to the frequency‚ type and size of earthquakes experienced over a period of time. Measurement: Earthquakes are measured with the help of seismometers. The moment

16‚ 2014 Kobe vs Northridge Earthquake Earthquakes can be devastating natural disasters as experienced in the Kobe earthquake in Japan. However‚ earthquakes are not what kill people‚ being unprepared is what causes the most harm. In the Northridge earthquake in California which was of very similar magnitude to the Kobe earthquake there were far less casualties. However‚ being prepared was not the difference in these cases. Factors that created such a huge difference in damage in Kobe were the

faults lead to be a lot more destruction. Earthquakes are a trembling or shaking of the ground caused by a sudden release of energy stored in rocks beneath earths surface. Earthquakes appear all over the planet‚ and there are many different sizes. Some earthquakes destroy entire cities while others only shake the ground for a moment. Faults are one of the causes of earthquakes‚ which I will tell about soon as well as the hazards and benefits they give. Earthquakes can be caused in many ways‚ some even
