Earthquakes in Australia Australia is a very lucky country that suffers very few earthquakes or volcanic eruptions. Earthquakes are caused by converging plates (usually subducting)‚ and there a 4 different types of waves in two categories; firstly there is Body waves which are broken into primary and secondary waves (these travel through the earth) Surface waves travel through only the crust and are called Love and Rayleigh. These Waves (the earthquakes) are measured by a seismograph/ a device that

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

Comparing Kobe and Sichuan Earthquake- “The wealth of a country influences the nature of the earthquake event experienced there”. With reference to the Kobe earthquake (1995) and Sichuan earthquake (2008)‚ decide whether this statement is true or not. This statement can be true in a number of ways‚ because an MEDCs have generally better infrastructures made for withstanding huge earthquakes unlike LEDCs where houses (especially squatter settlements) are damaged very easily and this makes the

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

When I think back to the news coverage that followed the earthquake in 2010 one thing that stands out is the word tragedy. It did not seem to matter what newspaper‚ news program‚ or website the coverage came from‚ all of them were using that word. In first day or two the word tragedy was often paired with disaster or horrible and the images of complete destruction flashed across the screen. Between the pictures and video and the word usage of the reporters it was clear that the situation was very

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
