Amplitude of different phases

Question 1

What happens to amplitude of first p-wave?

Answer 1

It decreases (“attenuates”) systematically the further away from the seismometer station is from the earthquake

Question 2

What is amplitude decreases converted to?

Answer 2

“specific attenuation factor”

Question 3

What happens to a wave travelling through earth?

Answer 3

It will compress and extend and will suffer reflection an refraction which causes a loss of energy overtime

Question 4

What happens if specific attenuation factor is high?

Answer 4

Then the rock is strong

Question 5

What happens if specific attenuation factor is low?

Answer 5

Then the rock is weak
