Information/Questions/Answers
What type of monitoring device(s) is used for my particular fault?
tilt meter is used to measure a normal fault.
How does the device work?
it measures tilting or raising of the ground.
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?
-- Roman numerals are being used for the Mercalli scale. --The farther the shaking is from the epicenter, the lower the number on the Mercalli scale.
I-III Feels like a passing truck and unstable items fall.
IV-VI Slight damage; people run outside.
VII-IX Moderate to heavy damage buildings fall from their foundations.
X-XII Great destruction, ground cracks and buildings are falling, waves are seen on the surface. -- Numbers are used to find how big the earthquake was. -- Moment Magnitude measures earthquakes all sizes, near or far and the strength of the rocks when the fault slipped.
Which is the method most used by seismologists today? Why?
seismometers, because it helps measure underground movements and show where it took place.

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.
