Friedemann Samrock from ETH Zurich visited Aluto volcano in May 2016 and sent some astonishing pictures of a crater lake forming during the rainy season. RiftVolc related field work so far has mainly been carried out in the dry season (Oct-Feb), so we were very curious to see this drastic seasonal change in the landscape. The presence of a lake could have implications for the hydrothermal system underneath Aluto regarding the interaction between water and magma.
