The Ijen vulcan’s crater located in east Java Island, Indonesia has a Blue Flame Lava Phenomenon.
The island – essentially lava that cooled after breaking through the water’s surface – began forming this month (December 2011) between Yemen and Eritrea among the Zubair archipelago, a group of small islands that come from a submarine shield volcano.
After fears of more activity during Wednesday’s full moon, Mount Mayon has actually quietened down, sparking new fears that the crater has plugged itself. If this has happened, then there is an even higher likelihood of an explosive eruption in the not to distant future.
Mount Mayon has been spewing lava and flaming rocks, some as big as cars for the last month. Now scientist have warned that Wednesday full moon could spark off a major eruption.
