Seismic Gap Tsunami Liquefaction Aftershock 2 / 20 The measure of damage done by an earthquake including its effect on people, structures, and the natural environment (measured by Modified Mercalli Scale) damage rate greatness magnitude intensity 3 / 20 Which scale rates earthquakes based on the amount of damage done? Seismogram Shakey Scale Mercalli Intensity Scale Richter Magnitude Scale Bernoulli Scale 4 / 20 How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale? 100 times bigger 10 times bigger 1 time bigger 1000 times bigger 5 / 20 The epicenter of an earthquake is ________ the focus beside next to above under 6 / 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 7 / 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 I disaster is what could happen, a hazard is after it has an impact on humans A hazard is what could happen, a disaster is after it has an impact on humans 8 / 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 allows the foundation of the building to move while keeping the rest of the building stable. It increases the weight of the building, which makes it more difficult to move. It counteracts the motion of the building when it sways by moving in the opposite direction. 9 / 20 Too little rain can cause ________ earthquake volcanic eruption volcanic eruption droughts 10 / 20 The point on the surface of the earth directly above the focus of an earthquake. surface wave energy release center focus epicenter 11 / 20 What is the benefit of flexible pads? 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. The flexible pads move the seismic waves into other open area locations. The flexible pads absorb the seismic waves and prevent them from shaking the building. 12 / 20 What does a seismograph measure? The amount of shaking of the crust. The amount of damage an earthquake causes. The amount of oil and gas underground. The temperature of the earth's core. 13 / 20 Pancaking is ............ the trapping of cars on a freeway during an earthquake the collapse of soil layers during an earthquake the collapse of a building during an earthquake breakfast on a Sunday morning 14 / 20 The location with the largest concentration of volcanoes in the world is called the... Ring of Fire Great Plate Boundary Volcano Alley Hot Spot 15 / 20 Richter Scale and Moment Magnitude are similar in that they measure liquefaction tsunami energy of the earthquake landslides 16 / 20 An earthquake scored high on the Richter scale but low on the Mercalli scale. Why? It damaged a lot of buildings. It probably happened in an area with no people. It is impossible to know. It was a fast earthquake. 17 / 20 Why an earthquake causes death, injury, and property damage? because the amplitude of waves is recorded by seismograph because the earthquake releases magma to the Earth's surface because the earthquake size is measured using the Richter scale because the released seismic waves cause the Earth's surface to shake 18 / 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 for both houses can't be measured. The damage caused by the earthquake is more severe in house A than in house B. The damage caused by the earthquake is more severe in house B than in house A. 19 / 20 Which of the following scales is NOT used to measure earthquakes? Modified Mercalli Intensity Scale Volcanic Explosivity Index Scale Richter magnitude scale Moment Magnitude Scale 20 / 20 Mercalli Scale measures ........................... in an earthquake. earthquake tremors all answers are correct liquefaction damage to structures and people Your score is 0% Restart quiz Go to the Quizzes Page
