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