The flexible pads transform the energy carried by the seismic waves into electricity. 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 seismic waves don't pass through the flexible pads and divert. 4 / 20 Mercalli Scale measures ........................... in an earthquake. all answers are correct damage to structures and people liquefaction earthquake tremors 5 / 20 The location with the largest concentration of volcanoes in the world is called the... Hot Spot Volcano Alley Ring of Fire Great Plate Boundary 6 / 20 The measure of damage done by an earthquake including its effect on people, structures, and the natural environment (measured by Modified Mercalli Scale) intensity damage rate magnitude greatness 7 / 20 What does a seismograph measure? The amount of oil and gas underground. The amount of shaking of the crust. The temperature of the earth's core. The amount of damage an earthquake causes. 8 / 20 How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale? 10 times bigger 1 time bigger 100 times bigger 1000 times bigger 9 / 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 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 increases the weight of the building, which makes it more difficult to move. It allows the foundation of the building to move while keeping the rest of the building stable. 10 / 20 What is the difference between a natural hazard and a natural disaster? Hurricanes and tsunamis are natural disasters, but earthquakes and volcanoes are hazards They are exactly the same A hazard is what could happen, a disaster is after it has an impact on humans I disaster is what could happen, a hazard is after it has an impact on humans 11 / 20 What is the temporary state in which loose soil and rock materials take on the property of quicksand? Seismic Gap Aftershock Tsunami Liquefaction 12 / 20 Pancaking is ............ breakfast on a Sunday morning the collapse of a building during an earthquake the trapping of cars on a freeway during an earthquake the collapse of soil layers during an earthquake 13 / 20 Which scale rates earthquakes based on the amount of damage done? Bernoulli Scale Seismogram Shakey Scale Richter Magnitude Scale Mercalli Intensity Scale 14 / 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 30 times 1000 times 100 times 15 / 20 The epicenter of an earthquake is ________ the focus beside under next to above 16 / 20 Which of the following scales is NOT used to measure earthquakes? Modified Mercalli Intensity Scale Richter magnitude scale Moment Magnitude Scale Volcanic Explosivity Index Scale 17 / 20 Where is the damage caused by the earthquake more severe in house A or house B? 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. The damage caused by the earthquake is more severe in house A than in house B. The damage caused by the earthquake for both houses can't be measured. 18 / 20 Richter Scale and Moment Magnitude are similar in that they measure landslides tsunami liquefaction energy of the earthquake 19 / 20 Too little rain can cause ________ earthquake volcanic eruption droughts volcanic eruption 20 / 20 An earthquake scored high on the Richter scale but low on the Mercalli scale. Why? It damaged a lot of buildings. It is impossible to know. It was a fast earthquake. It probably happened in an area with no people. Your score is 0% Restart quiz Go to the Quizzes Page
