Outline Format Introduction 1. Over 70% of Japan consists of mountains. The country also has over 200 volcanoes. Raised floors help indicate when to take off slippers or shoes. At the entrance to a home in Japan‚ the floor will usually be raised about 6 inches (15.24 cm.) indicating you should take off your shoes and put on slippers. If the house has a tatami mat room‚ its floor may be raised 1-2 inches (2.54-5.08 cm.) indicating you should take off your slippers. 2. Interested. 3. Tonight I

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

Test 3 Study Guide Test 3 will cover chapters 5‚ 6‚ 7‚ 8‚ 9‚ and the material presented on Hurricane Katrina and the recent earthquake in Japan. It will have 42 multiple-choice (2 points each) and 4 short answer/diagrams (4 points each). Topics for review * Earthquake terms: * fault: break (fracture) in a rock * rupture: breaking of rock along a fault * hypocenter (focus): rupture point of rock below surface * epicenter: point on earth surface directly above hypocenter

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

How many minutes did the shaking last? The shaking lasted 4.5 minutes. 2. What was the magnitude of the earthquake? The magnitude of the earthquake was 9.2. 3. This earthquake occurred just as geologists were figuring out plate tectonics. What principle of plate tectonics did the earthquake confirm

The largest earthquake recorded in the 20th century is the 1960 Valdivia earthquake‚ also known as the Great Chilean earthquake which occurred on May 22‚ 1960 and hit approximately 100 miles off the coast of Chile‚ which is parallel to the city of Valdivia. With a rate of 9.5 on the moment magnitude scale‚ this earthquake occurred in the afternoon and lasted approximately 2 minutes (brit). After just thirty minutes of the major earthquake‚ a foreshock shook the area near the towns of Valdivia and

EARTHQUAKES Introduction and Terminology • Vibrations in the earth’s crust that occur when strain in the crust is suddenly released by displacement along a fault line • Focus = point at which an earthquake originates inside the earth. May be many km below surface • Epicentre = the point on the earth’s surface directly above the focus. Strongest shock normally felt here. Most damage usually occurs here. • Seismology = the study of earthquakes – from Greek – seio – to shake

than any other nation in the world‚ Japan is shaped by its geography to a tremendous extent. Technically classified as an archipelago‚ Japan is a curved chain of four islands (Hokkaido‚ Honshu‚ Shikoku‚ and Kyushu‚ plus over a thousand smaller islands). However‚ it is first and foremost an island nation‚ a fact which isolated Japan from the rest of the world. The second largest influence in Japanese geography is the size of the nation. The total area of Japan proper is a little under 143 thousand

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
