Krakatau volcano (Sunda Strait, Indonesia): sudden eruption yesterday sends ash to 1,500 m altitude

During the past weeks, there have been no particular signs of unusual activity and relatively few quakes at the volcano (only about 6 daily quakes on average), which is why the explosion came as a surprise.
