As scary as it seems, no! Krakatoa actually reformed after an island destroying eruption in 1883. Now Krakatoa is back and has erupted visibly, (not underwater) periodically between around the 1930's to 2007. Thankfully these eruptions were small and any major eruption like that in 1883 will likely occur in hundreds of years.
I have been doing some research on volcanoes. Scientists have not made another name for shield volcanoes yet. I can not believe it. They have them for cinder cone, and composite volcanoes.
