Tsunami and Earthquake Sion Hau 7D 31/07/11 An earthquake occurred in Sendai‚ Japan on the 11th of March in 2011; this earthquake also resulted in a tsunami. The earthquake measured at magnitude 8.9-9.0 on the Richter scale‚ the scale is measured in powers of ten (e.g. magnitude 2.0 is ten times more than magnitude 1.0). Japan sits on the Ring of Fire (an area encircling Pacific Ocean that has high volcanic and earthquake activity)

March 27‚ 1964 a magnitude 9.2 earthquake hit Alaska its epicenter located in Prince William Sound‚ 75 miles east of Anchorage. This earthquake was and still is the second larges earthquake ever recorded (Christensen). The plates involved In this major earthquake were the Pacific plate and North American plate. This subduction zone is know as Aleutian-Alaska megathrust zone (Sokolowski). This region was known for its active plate tectonics‚ but this earthquake did come as a surprise to the public

Mikela Sammy U62 Caribbean Studies QUESTION: Access the measures that Caribbean countries could realistically undertake to minimize the danger posed by earthquakes. An earthquake is a sudden and violent shaking of the ground‚ sometimes causing great destruction‚ as a result of movements within the earth’s crust or volcanic action. This happens when two blocks of the earth suddenly slip past one another. The Earth’s crust is made up of about a dozen plates on which the continents and oceans

I chose to research earthquakes and the prediction of earthquakes because I was curious as to how they work. In this paper‚ I will discus the history of earthquakes‚ the kinds and locations of earthquakes‚ earthquake effects‚ intensity scales‚ prediction‚ and my own predictions. An earthquake can be defined as vibrations produced in the earth’s crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations

powerful the earthquakes that the Anatolian fault produced. So what is the history of the fault? Where did other earthquakes happen? How many people died? Is there another earthquake on the horizon? Well I am glad you asked. The country of Turkey lies on the Anatolian Plate. The fault is a strike-slip fault much like the commonly known San Andreas Fault in the United States. The Anatolian fault is almost as active as the San Andreas‚ and is very well known for the size of the earthquakes that it produces

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

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‚

What are Earthquakes? The actual defining of a earthquake is: A sudden and violent shaking of the ground‚ sometimes causing great destruction‚ as a result of movements within the earth’s crust or volcanic action. Basically what its saying is that when a tectonic plate slips past another and when that happens its called a fault or fault plane‚ but when a earthquake happens it has been proven that it can deform the earths crust permanently. Something interesting is

Prediction Why didn’t scientists know about the faults that caused the two earthquakes? Prior to September 4th‚ there were no surface signs of the Greendale Fault or the fault that generated the Lyttelton aftershock and there was no evidence for seismicity on these faults (i.e. ‘foreshocks’). Seismic surveys have located some ‘hidden’ faults across parts of the Canterbury Plains‚ but these particular regions had not been surveyed for this purpose. An oil-gas seismic survey had been carried out
