Abstract: Kelud volcano in East Java, Indonesia erupted on April 14, 2014. The previous activity in 2007 produced the lava dome that influenced the characteristic of the eruption. The progress on the destruction of the lava dome might give the information on the type of the eruption whether a single eruption as usual or a prolonged activity. While the direct observation to the crater was not possible due to the high degree of the danger, remote sensing method provides the information on the state of lava dome destruction and the configuration of the crater. This information would contribute the important basis for the issuance of go-return sign for the evacuees terminating the crisis. The remote sensing interpretation used satellite imageries taken a few days after the eruption. The interpretation used also the terrestrial photographs taken after the 2007 dome formation. Topographic map prepared by the Volcanological Surveys in 1968 provides the basis for the estimation and calculation. The preliminary information of the configuration of the crater would contribute to the planning for reconstruction and repair of the draining tunnel system of Kelud volcano. The amount of water in the coming craters lake might exceed in order of 20 millions cubic meters. The lava dome extended about 300 meters in E-W and around 200 meters in N-S directions. The volume estimation gives the figure of 2.7 to 3 millions cubic meters. Extended to the root the volume might increase to about 5 to 6 millions cubic meters. The new hole left by the April 14 eruption occupied 70 % of the lava dome with the diameter of 175 meters and the total hollow of about 3.5 to 4.2 millions cubic meters.
