What are some effects of earthquakes?
Type: aftershock
How does it work? it comes after the big Earthquake
Real example After the big Earthquake sometime the
Aftershock comes or sometimes it doesn’t it can
Take weeks to months for the aftershock to come
Type: Liquedfaction
How does it work? What happens is that the rock
And the dirt become mud
Real example Liquefaction occurs wen the soil is wet and an Earthquake appears and it makes it shake and turn into mud

Type: Shaking
How does it work? Shaking s waves and surface
Waves move side to side up and down. And the type of rock and soil determine where and how much the ground shakes
Real example when the ground is shaking it can cause a avalanche or a landslide
Type: tsunami
How does it work? Tsunamis occur wen the waves push back and move forward with a lot of
Pressure. A tsunami spreads out from the Earthquakes epicenter.
Real example when an Earthquake jolts the ocean floor, plate movement causes the ocean floor to rise slightly and push water out it way

Which is the method most used by seismologists today? Why?
seismometers, because it helps measure underground movements and show where it took place.
Content Question: How do we monitor and measure the intensities of earthquakes?
Guiding Questions
Information/Questions/Answers
What type of monitoring device(s) is used for my particular fault?
laser-ranging device
How does the device work?
a laser-ranging device uses a laser beam to detect horizontal fault movement.
Choose two methods of measurement to describe (Richter, Mercalli , or Moment Magnitude ) and include diagrams
Are numbers or Roman numerals used?
How is damage described?
Richter scale: it assigns the earthquake a number that determines the magnitude.
Mercalli: the mercalli scale rates earthquakes according to their intensity.
The mercalli scale uses roman numerals, and the richter scale uses regular numbers.
Which is the method most used by seismologists today? Why?
moment magnitude scale
