The crater lake of Kelud reappeared in the first year after the 2014 eruption, were the previous lava dome once stood. The lava-dome back then almost covered the whole lake area, and had displaced most of its water few years prior to the eruption. The lava dome was completely destroyed in the 2014 eruption. Since my last visit to Kelud in 2016, its seems that the lake have turned yellow-orange, from previously having a green color (see image comparison below). More vegetation can also be seen in the area surrounding the lake, as should be expected. Most of the vegetation, if not all, were destroyed in the 2014 eruption.
