Hydrologic oddities: Linow lake

Lake Linow in Tomohon, North Sulawesi, Indonesia slowly changes color from red to green to blue every now and then. This is because there are sulfuric vents that change the mix of gases in the water. The shallows bubble and let off white smoke.

Here's a satellite image of the lake from Google Earth (in the green phase)

And some others from the ground...
