The Center for Volcanology and Geological Hazard Mitigation (PVMBG), Surono said this is a rise in status that was set on Friday, September 30, 2011 evening at 24.00. The reason for the elevated status is because of the high-intensity level of earthquakes.
Today, for example. "On October 2, 2011, at 00.00 until 12.00, there are 2745 recorded seismic events," said Surono, when he was contacted by VIVAnews.com, Sunday, October 2, 2011. Earthquakes under Mount Anak Krakatau, Surono added, were even felt all along the island of Anak Krakatau.
"The swarm of tremors are continuous and although small, 2 on the Richter scale, they are cause for concern because they are felt constantly," he added. He explained, almost since 2007, Krakatau has been stirred by unrest. "In a moment, it stopped, and erupted in 2009. I think this mountain is always in danger of erupting," he added. - Viva News (translated)
