Some 17 other people are still missing.<br />''<br />''Emergency teams and rescue dogs continue to look for survivors and bodies in the debris. The operation has been complicated by dangerous conditions and bad weather in the area. The volcano also remains active, with smaller eruptions continuing since the weekend.<br />''<br />''Indonesian President Joko Widodo visited the area on Tuesday and indicated some 2,000 families could be moved because of the ongoing threat.<br />''<br />''Mt Semeru rises 12,000 ft above sea level and is among Indonesia's almost 130 active volcanoes.
