Source: The Great Interpretation of Dreams (Ibn Sirin)
An earthquake in a dream indicates fear of the ruler or a general affliction that will befall that place. If one sees the earth shaking with him, it indicates the emergence of hidden matters. The shaking of the earth indicates illness, war, or strife.

An earthquake indicates travel or a change in conditions. If the earthquake is in a specific place, it indicates a hardship that will afflict its people. If one sees a mountain moving from its place, it indicates the death of a king or a great man.

An earthquake is interpreted as torment and worry. Whoever sees the earth shaking will fall into worry and hardship. If the earthquake is light, it is a minor worry.
