Krakatau's major explosive eruption earlier this month did something quite unusual; it seemingly created two new vents which created brand new albeit temporary volcanic islands. And these new vents, which have resulted in an expanded exclusion zone at the volcano are somewhat interesting in terms of their location. Specifically, because they are vaguely close to the locations of two destroyed volcanic cones that existed before Krakatau's 1883 eruption.
