Indonesia has raised its alert level, widened an exclusion zone and ordered all flights to steer clear as volcanic eruptions threaten to trigger a second deadly tsunami.
There is no let up from Anak Krakatau spewing lava and rocks high into the sky - and constantly threatening to send another killer wave toward the coast.
The chief of Indonesia's Geological Agency says they've raised the danger alert to the second-highest level, with further eruptions expected.

The exclusion zone around the island has been expanded from two to five kilometres, and air traffic controllers have rerouted flights to avoid the area.
Satellite imagery shows the volcano before and after Sunday's eruption, revealing the crater collapse. It set off an undersea landslide, which triggered the tsunami that killed hundreds.
The death toll has climbed to 430 but that could rise, with more than 150 still missing and many more injured.
Banten residents have started clearing debris, but thousands have been left homeless.
Continuous heavy rains have only added to the problem, with half of the coastal town of Labuan submerged.
This year, Indonesia has already suffered its worst annual death toll from natural disasters in more than a decade, and they're nervous there's still more to come.
