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

San Francisco have all experienced a fault shift. In the case of Houston‚ the likelihood of an earthquake is extremely low. The instances of a fault shift on that area of the North American Plate don’t occur often. Earthquakes that occur are not by normal means of plates shifting but from the process of fluid extraction (Fehling 19). Seattle on the other hand has a very high probability of an earthquake occurring. There are three different types of quakes that the city experiences crustal quakes‚

The largest earthquake ever occurred in the 20th century was the Valdivia Earthquake. As cited in the sources‚ the magnitude of this powerful earthquake was approximately 9.5 and totally destroyed communities near the epicenter. Because this great number of magnitude has a power to eradicate everything around it. Other earthquakes might be the larger but it’s the first one since accurate estimates of magnitude became possible. This was a megathrust earthquake which means that an earthquake occurred

examples of earthquakes‚ assess the extent to which attempts at prediction and mitigation may have influenced the impact of the hazard. An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. Earthquake is a major threat to the human and natural environments‚ in which people died‚ buildings collapsed and cities destroyed. Prediction and mitigation are usually conducted in order to reduce the impact of an earthquake on environment. Earthquake prediction

Earthquakes By: Kayla Marie Vargas Period 4 In earth science they talk a lot about different Earthquakes‚ volcanoes‚ the weather‚ different rocks‚ and etc. But never did you really get in details of what is any of them. Well I did research and found out that an earthquake which is also known as a quake‚ tremor or temblor is a 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
