State the types of earthquakes based on focus and Richter scale. 

1 Answer

Answer :

Earthquakes based on focus distributed in three general depth ranges:

i) Shallow earthquakes originate within about 60 kilometers of the surfaces

ii) Intermediate earthquakes have foci between 60 to 300 kilometers down

iii) Deep seated earthquakes originate at depths below 300 kilometers

 The Richter scale of magnitude infact, classifies the various shocks in magnitude varying from 1to 10

i) Magnitude from 3 to 9 maximum known as 8.9

ii) Smaller than 5 causes several damages

iii) Magnitude 2 represents the smallest tremor that can be felt.
