Liquefaction Aftershock Seismic Gap Tsunami 2 / 20 Which scale rates earthquakes based on the amount of damage done? Seismogram Shakey Scale Richter Magnitude Scale Bernoulli Scale Mercalli Intensity Scale 3 / 20 An earthquake scored high on the Richter scale but low on the Mercalli scale. Why? It probably happened in an area with no people. It damaged a lot of buildings. It is impossible to know. It was a fast earthquake. 4 / 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 5 / 20 What does a seismograph measure? The amount of oil and gas underground. The amount of shaking of the crust. The amount of damage an earthquake causes. The temperature of the earth's core. 6 / 20 Richter Scale and Moment Magnitude are similar in that they measure tsunami landslides liquefaction energy of the earthquake 7 / 20 Too little rain can cause ________ volcanic eruption volcanic eruption earthquake droughts 8 / 20 Mercalli Scale measures ........................... in an earthquake. liquefaction earthquake tremors all answers are correct damage to structures and people 9 / 20 Where is the damage caused by the earthquake more severe in house A or house B? 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. The damage caused by the earthquake is more severe in house B than in house A. The damage caused by the earthquake is the same in both houses A and B. 10 / 20 The measure of damage done by an earthquake including its effect on people, structures, and the natural environment (measured by Modified Mercalli Scale) magnitude damage rate intensity greatness 11 / 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 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. 12 / 20 Why an earthquake causes death, injury, and property damage? because the earthquake size is measured using the Richter scale because the released seismic waves cause the Earth's surface to shake because the earthquake releases magma to the Earth's surface because the amplitude of waves is recorded by seismograph 13 / 20 How much bigger is a magnitude 8 earthquake compared to magnitude 7 one on the Richter Scale? 1000 times bigger 10 times bigger 100 times bigger 1 time bigger 14 / 20 The point on the surface of the earth directly above the focus of an earthquake. focus energy release center surface wave epicenter 15 / 20 The epicenter of an earthquake is ________ the focus under above next to beside 16 / 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 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. It creates an "invisible cloak" so that energy is rerouted around the building, rather than through the building. 17 / 20 Which of the following scales is NOT used to measure earthquakes? Volcanic Explosivity Index Scale Modified Mercalli Intensity Scale Richter magnitude scale Moment Magnitude Scale 18 / 20 Pancaking is ............ breakfast on a Sunday morning the collapse of a building during an earthquake the collapse of soil layers during an earthquake the trapping of cars on a freeway during an earthquake 19 / 20 The location with the largest concentration of volcanoes in the world is called the... Ring of Fire Volcano Alley Hot Spot Great Plate Boundary 20 / 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? 1000 times 3000 times 30 times 100 times Your score is 0% Restart quiz Go to the Quizzes Page
