4 Oct 11 – Anak Krakatau (Child Of Krakatoa), a volcanic island between the islands of Java and Sumatra in Indonesia, erupted today propelling huge columns of ash and rock high into the air.
Dark gray areas are primarily lava flows deposited in the 1970s, ’80s, and ’90s. These flows are topped by a young cinder cone near the center of the island. Green vegetation covers older lavas along the eastern coastline. Image NASA. Instrument: EO-1 – ALI
The Indonesian Volcanology and Geology Disaster Mitigation Centre reported that an estimated 6,000-7,000 volcanic earthquakes were recorded daily during the weekend and on Monday. Daily earthquake totals usually do not exceed 100-200.
Seismologists are still attempting to determine the type and scale of the ongoing eruption.
The eruption at Anak Krakatau is the biggest since January.
