The damage caused by the earthquake for both houses can't be measured. The damage caused by the earthquake is the same in both houses A and B. The damage caused by the earthquake is more severe in house B than in house A. 5 / 20 What is the temporary state in which loose soil and rock materials take on the property of quicksand? Liquefaction Aftershock Seismic Gap Tsunami 6 / 20 The epicenter of an earthquake is ________ the focus beside next to above under 7 / 20 When using the richter scale, each increase on the scale represents ten times the amount of ground motion recorded on a seismogram. How much more of a magnitude is a 7 earthquake than a magnitude 4 earthquake? 3000 times 100 times 30 times 1000 times 8 / 20 The measure of damage done by an earthquake including its effect on people, structures, and the natural environment (measured by Modified Mercalli Scale) greatness intensity magnitude damage rate 9 / 20 What is the benefit of flexible pads? The flexible pads absorb the seismic waves and prevent them from shaking the building. The flexible pads move the seismic waves into other open area locations. The flexible pads transform the energy carried by the seismic waves into electricity. The seismic waves don't pass through the flexible pads and divert. 10 / 20 Taipei 101 has the largest tuned mass damper in the world located between the 87th and 92nd levels. How does this tuned mass damper help to make the building more resistant to earthquake damage? It increases the weight of the building, which makes it more difficult to move. It creates an "invisible cloak" so that energy is rerouted around the building, rather than through the building. It counteracts the motion of the building when it sways by moving in the opposite direction. It allows the foundation of the building to move while keeping the rest of the building stable. 11 / 20 Pancaking is ............ the collapse of a building during an earthquake the collapse of soil layers during an earthquake breakfast on a Sunday morning the trapping of cars on a freeway during an earthquake 12 / 20 The point on the surface of the earth directly above the focus of an earthquake. epicenter surface wave focus energy release center 13 / 20 Richter Scale and Moment Magnitude are similar in that they measure liquefaction tsunami energy of the earthquake landslides 14 / 20 What is the difference between a natural hazard and a natural disaster? I disaster is what could happen, a hazard is after it has an impact on humans They are exactly the same A hazard is what could happen, a disaster is after it has an impact on humans Hurricanes and tsunamis are natural disasters, but earthquakes and volcanoes are hazards 15 / 20 How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale? 1000 times bigger 100 times bigger 10 times bigger 1 time bigger 16 / 20 What does a seismograph measure? The amount of damage an earthquake causes. The amount of oil and gas underground. The temperature of the earth's core. The amount of shaking of the crust. 17 / 20 Mercalli Scale measures ........................... in an earthquake. all answers are correct damage to structures and people earthquake tremors liquefaction 18 / 20 The location with the largest concentration of volcanoes in the world is called the... Great Plate Boundary Hot Spot Ring of Fire Volcano Alley 19 / 20 An earthquake scored high on the Richter scale but low on the Mercalli scale. Why? It is impossible to know. It probably happened in an area with no people. It damaged a lot of buildings. It was a fast earthquake. 20 / 20 Which scale rates earthquakes based on the amount of damage done? Bernoulli Scale Seismogram Shakey Scale Richter Magnitude Scale Mercalli Intensity Scale Your score is 0% Restart quiz Go to the Quizzes Page
