How much more of a magnitude is a 7 earthquake than a magnitude 4 earthquake? 30 times 100 times 1000 times 3000 times 2 / 20 The location with the largest concentration of volcanoes in the world is called the... Volcano Alley Great Plate Boundary Hot Spot Ring of Fire 3 / 20 What is the benefit of flexible pads? 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 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 magnitude greatness intensity 5 / 20 The point on the surface of the earth directly above the focus of an earthquake. energy release center surface wave focus epicenter 6 / 20 What is the difference between a natural hazard and a natural disaster? A hazard is what could happen, a disaster is after it has an impact on humans They are exactly the same Hurricanes and tsunamis are natural disasters, but earthquakes and volcanoes are hazards I disaster is what could happen, a hazard is after it has an impact on humans 7 / 20 What does a seismograph measure? The temperature of the earth's core. The amount of oil and gas underground. The amount of shaking of the crust. The amount of damage an earthquake causes. 8 / 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 probably happened in an area with no people. It was a fast earthquake. 9 / 20 Too little rain can cause ________ earthquake volcanic eruption volcanic eruption droughts 10 / 20 Pancaking is ............ the collapse of soil layers during an earthquake the trapping of cars on a freeway during an earthquake breakfast on a Sunday morning the collapse of a building during an earthquake 11 / 20 Where is the damage caused by the earthquake more severe in house A or house B? 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. The damage caused by the earthquake is more severe in house A than in house B. 12 / 20 Mercalli Scale measures ........................... in an earthquake. damage to structures and people liquefaction earthquake tremors all answers are correct 13 / 20 What is the temporary state in which loose soil and rock materials take on the property of quicksand? Liquefaction Aftershock Tsunami Seismic Gap 14 / 20 How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale? 10 times bigger 100 times bigger 1000 times bigger 1 time bigger 15 / 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 allows the foundation of the building to move while keeping the rest of the building stable. 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. 16 / 20 Which of the following scales is NOT used to measure earthquakes? Moment Magnitude Scale Modified Mercalli Intensity Scale Volcanic Explosivity Index Scale Richter magnitude scale 17 / 20 Why an earthquake causes death, injury, and property damage? because the released seismic waves cause the Earth's surface to shake 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 18 / 20 Richter Scale and Moment Magnitude are similar in that they measure landslides energy of the earthquake tsunami liquefaction 19 / 20 Which scale rates earthquakes based on the amount of damage done? Seismogram Shakey Scale Richter Magnitude Scale Mercalli Intensity Scale Bernoulli Scale 20 / 20 The epicenter of an earthquake is ________ the focus under next to beside above Your score is 0% Restart quiz Go to the Quizzes Page
