There are limits to the accuracy of estimating magnitude, especially for large earthquakes. Places like California, where earthquakes constantly occur, have buildings and structures designed to survive earthquakes. Lv 5. Negative: Tsunami and Flooding. From the earthquake features discussed, we can see that despite the Seddon earthquake having a greater magnitude and similar type of fault movement, it was the fact that the Christchurch earthquake carried a lot more power and force with its initial ground movement and … The emotional problems that come with earthquakes differ from other natural hazards because they usually strike without warning and because of the force and destructive effects that come with it. Thats all I could think of!ADVANTAGE: but i love 2 watch those shaking b**bs of my neighbourWhat do you think of the answers? Many loess slopes failed during the New Madrid, Missouri, earthquakes of 1811-12.

Whar are the disdvantages of an earthquake? Buildings and other structures sometimes even collapse, because the foundation cannot handle the force of the shaking ground. and only 45 being over magnitude 4. Sand boils can cause local flooding and the deposition or accumulation of silt.Lateral spreads involve the lateral movement of large blocks of soil as a result of liquefaction in a subsurface layer.
Flow failures usually form in loose saturated sands or silts on slopes greater than 3 degrees. Earthquakes, until recently, have been measured on the Richter scale. Disadvantages of an Earthquakes! Hugh Ross, one of the astrophysicists in Royal Astronomical Society in Canada, said that “In the absence of an earthquake or tectonic activity, the nutrients needed by living on the land would be undermined from the continent and collected in the oceans.”Steve Johnson is an avid and passionate writer with more than five years of experience.

Combinations of the strike-slip type and the other two types of faulting can be found. Disadvantages caused by the earthquake disaster directly: The destruction of buildings and structures, such as houses collapsed, bridges broken down, cracking dams, rail deformation and so on. Horizontal movements on lateral spreads commonly are as much as 10 to 15 feet, but, where slopes are particularly favorable and the duration of ground shaking is long, lateral movement may be as much as 100 to 150 feet. An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities.
Without warning an earthquake can strike suddenly and violently and can happen any time of the day or night. Soil avalanches occur in some weakly cemented fine-grained materials, such as loess, that form steep stable slopes under nonseismic conditions. Most fault displacement is confined to a narrow zone ranging from 6 to 1,000 feet in width, but separate subsidiary fault ruptures may occur 2 to 3 miles from the main fault. Negative: Devastation to Manmade Structures. The area subject to disruption by surface faulting varies with the length and width of the rupture zone.Liquefaction is not a type of ground failure; it is a physical process that takes place during some earthquakes that may lead to ground failure. This transfer of load increases pressure in the pore water, either causing drainage to occur or, if drainage is restricted, a sudden buildup of pore-water pressure. It can destroy vegetation, human structures and even whole coastal communities. Movement takes place in response to the ground shaking generated by an earthquake. The Richter scale measures the magnitude of an earthquake (how powerful it is). Answer Save. Body and surface waves cause the ground, and consequently a building, to vibrate in a complex manner. The great distance between wave crests prevents tsunamis from dissipating energy as a breaking surf; instead, tsunamis cause water levels to rise rapidly along coast lines.Tsunamis and earthquake ground shaking differ in their destructive characteristics.
