Kelimutu, a small volcano on Flores Island, is noted for its three crater lakes of different colors. This aerial view from the SW shows Tiwu Ata Mbupu at the lower left, and the two craters of Tiwu Nua Muri Kooh Taiand Tiwu and Ata Polo at the upper right. Water color varies periodically with variations of blue, green, and red. Phreatic eruptions have occurred from the middle lake in historical time.
