FWIW, Krakatoa was the name of the first volcano. This one, as has been stated, is
Anak Krakatoa. In Bahasa Indonesia the word
anak means
child. Thusly, the name of the volcano which has arisen over the site of the previous volcano (which lost its head in the 1800s) is
Child of Krakatoa.
Just thought I'd throw this tidbit out there. Don't quite know why.
