How large is the new dome, and how does it compare to the 19801986 dome?
In July 2007, the volume of the new dome was 93 million cubic meters (121 million cubic yards). This is slightly larger than the volume of the 19801986 dome. The new dome grew a small additional amount from August 2007 to January 2008, but a thick winter snowpack in the crater this winter prevents us from measuring that value accurately.
