[quote]I want to know is did Mordor suffered an Earthquake when Isildur/Bilbo/Gollum said 'The Ring is Mine!'.[quote]

For clarification: earthquake, crashes and roars, etc happened when the Ring was destroyed, not when anyone claimed it as their own.

I agree with Firefoot...Frodo was fully aware of what the Ring was when he claimed it...course, probably so was Isildur. But, I wonder if the location of the claim on the Ring made a difference. A transfer of power had occurred in this very spot before...when Sauron made the Ring there. I believe that the Chambers of Fire (Sammath Naur) was where Sauron first put the ring on his finger and said the words to bring the ring to life. Frodo was in the same area as the previous transfer of power, and speaking words of claim to the Ring.
