Mount Kelud is one of active volcano in East Java. Mount Kelud is on border between Kediri and Blitar, about 27 kilometers east of Kediri town center. Since 15th century, mount Kelud has claimed more than 15.000 people lives. The eruption of Mount Kelud was in 1586 to take toll of about 10.000 lives. A system to divert the lava flow had been built in 1926 and is still functioning today.
In the 20th century, recorded mount Kelud erupted in 1901, 1919, 1951, 1966, and 1990, and in 2007 it again increased volcanic activity. Mount Kelud volcanic activity increased in late September 2007 and continued until November at the same year. It was on the mark with water temperature rising crater, increase in seismic tremor and changes color from green to white lake turbid. Status "alert" issued by the Center for Volcanologist and Geological Hazard Mitigation, beginning on October 16 ‘2007 the population within a radius of 10 kilometers from the mountain evacuated.
Due the high activity of these symptoms occur uniquely in history of mount Kelud with advent of white smoke from middle of lake and follow the lava dome in the middle crater lake since November 5 ‘2007. It was continued to grow until measuring 100 meters wide. Experts consider, lava dome is clogging of magma that no eruption is imminent. The energy was used to promote eruption lava dome eruption remainder of 1990. Since then, the activity decreases and the energy release on November 8, 2007 status mount Kelud scaled back to idle.
