“The last one in 1883 blew up 2/3rds of the island.”
Yes. If you look at the photos at the top of the thread, those islands around the volcano are actually remnants of the caldera that blew then.
I visited Anak Krakatoa on a sight-seeing ferry boat about 8 years ago. I had just finished reading a book about Krakatoa and the went to Indonesia for business. I was visiting Cilegon, which is very close. I couldn’t pass up the chance to go see where all the action had taken place.
I just dialed in Krakatau on Google Earth and the most current image is from Dec. 2014 and shows a smoke trail drifting off to the south east.
