Cinangka, Banten. The crater of Anak Krakatau in the Sunda Strait has expanded to a diameter of 25-26 meters, an Indonesian volcanologist says.
The news comes as the frequency of eruptions of the volcano, once misidentified as Krakatoa, increases: On Friday there were 615 eruptions, on Saturday 623 eruptions, and on Sunday 668.
Anton S Pambudi, a official from Banten province monitoring the eruptions, said the eruptions over the past two weeks had changed the shape of the crater.
He said the team would continue to monitor the volcano.
Banten Governor Ratu Atut Chosiyah said she believed that Anak Krakatau did not pose a threat and that the eruptions, which can be seen from the western tip of Java Island, were interesting to observe.
Krakatoa exploded in 1883, with the resulting tsunamis killing an estimated 40,000 people.
Authorities have warned that several other volcanoes in Indonesia are showing increased signs of activity. These include Mount Karangetang on Siau Island in North Sulawesi and Mount Ibu on Halmahera Island in North Maluku.
