How many earthquakes occur How many earthquakes occur each year felt by humans?each year felt by humans?
How many earthquakes occur each How many earthquakes occur each year only felt by seismographs?year only felt by seismographs?
What is the difference between What is the difference between the epicenter and focus?the epicenter and focus?
• Focus – point inside the Earth where an earthquake beginsEpicenter – point on Earth’s surface above focus
• An instrument that records vibrations in the ground and determines the location and strength of an earthquake
What are the waves of energy that What are the waves of energy that travel through the Earth called?travel through the Earth called?
What are the 2 scales used to What are the 2 scales used to measure earthquake strength?measure earthquake strength?
What is the difference between What is the difference between the Mercalli and Richter scales?the Mercalli and Richter scales?
• Mercalli Scale measures the strength of shaking and how much damage was caused to a city
• Richter Magnitude Scale measures the amount of energy released and what shows up on a seismogram
If you know the distance from the If you know the distance from the epicenter of an earthquake to 3 epicenter of an earthquake to 3
seismic stations how could you find seismic stations how could you find where the earthquake originated?where the earthquake originated?
• Draw a circle around each city with the radius being the distance away from the epicenter the city is. Once all three circles are drawn where they overlap is where the earthquake originated.
