Lesson #5 - MAGNITUDE AND INTENSITY

Question 1

• Refers to the amount of energy released by an earthquake as this ground shakes
• The more energetic an earthquake is, the higher the value of its ________.

Answer 1

Magnitude

Question 2

It is a scale used to measure the magnitude of an earthquake

Answer 2

Richter Scale

Question 3

• It is a machine used to determine the strength of an earthquake

Answer 3

Seismograph

Question 4

It is a process by which earthquakes are mapped using several seismograph

Answer 4

Triangulation

Question 5

It measures the force needed in order to generate the recorded siesmic waves which considers: RR, D of RM & EA of R

Answer 5

Moment Magnitude sclae
-Rock rigidity
- Distance of Rock movement
- Estemated Area of rupture

Question 6

Measure the amount of energy of an earthquake based on property damage
- Measured on the MMS
- PHILVOCS Provides a scale similar to MMS called PHILVOCS EIS

Answer 6

Intensity
- Modified Mercalli Scale
- PHILVOCS Earthquake Intensity Scale

Question 7
