How much more of a magnitude is a 7 earthquake than a magnitude 4 earthquake? 30 times 1000 times 3000 times 100 times 2 / 20 The location with the largest concentration of volcanoes in the world is called the... Great Plate Boundary Ring of Fire Volcano Alley Hot Spot 3 / 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 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. 4 / 20 Richter Scale and Moment Magnitude are similar in that they measure tsunami liquefaction landslides energy of the earthquake 5 / 20 An earthquake scored high on the Richter scale but low on the Mercalli scale. Why? It is impossible to know. It was a fast earthquake. It damaged a lot of buildings. It probably happened in an area with no people. 6 / 20 How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale? 1 time bigger 1000 times bigger 100 times bigger 10 times bigger 7 / 20 Why an earthquake causes death, injury, and property damage? because the earthquake size is measured using the Richter scale because the earthquake releases magma to the Earth's surface because the released seismic waves cause the Earth's surface to shake because the amplitude of waves is recorded by seismograph 8 / 20 Which scale rates earthquakes based on the amount of damage done? Richter Magnitude Scale Mercalli Intensity Scale Bernoulli Scale Seismogram Shakey Scale 9 / 20 The epicenter of an earthquake is ________ the focus next to above beside under 10 / 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 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 They are exactly the same 11 / 20 The point on the surface of the earth directly above the focus of an earthquake. focus epicenter surface wave energy release center 12 / 20 What is the benefit of flexible pads? The flexible pads transform the energy carried by the seismic waves into electricity. The flexible pads move the seismic waves into other open area locations. The seismic waves don't pass through the flexible pads and divert. The flexible pads absorb the seismic waves and prevent them from shaking the building. 13 / 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 greatness magnitude damage rate 14 / 20 Too little rain can cause ________ earthquake volcanic eruption volcanic eruption droughts 15 / 20 Mercalli Scale measures ........................... in an earthquake. all answers are correct liquefaction earthquake tremors damage to structures and people 16 / 20 What does a seismograph measure? The temperature of the earth's core. The amount of shaking of the crust. The amount of oil and gas underground. The amount of damage an earthquake causes. 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 for both houses can't be measured. The damage caused by the earthquake is more severe in house A than in house B. 18 / 20 Which of the following scales is NOT used to measure earthquakes? Modified Mercalli Intensity Scale Moment Magnitude Scale Volcanic Explosivity Index Scale Richter magnitude scale 19 / 20 Pancaking is ............ breakfast on a Sunday morning the collapse of soil layers during an earthquake the collapse of a building during an earthquake the trapping of cars on a freeway during an earthquake 20 / 20 What is the temporary state in which loose soil and rock materials take on the property of quicksand?
