Explanation:

When a subordinate clause (here, "When an earthquake jolted Pakistan in 2013") starts a sentence, it should be separated from the main clause ("the force caused ocean mud to rise to the surface, creating a small island in the middle of the Arabian Sea") by a comma. This is a basic rule of English punctuation for complex sentences.

When an earthquake jolted Pakistan in 2013, the force caused ocean mud to rise to the surface, creating a small island in the middle of the Arabian Sea.
