By trash, I’m not referring to the cast of Jersey Shore, although THAT would make for some excellent viewing.
This is what happens when a box of organic waste (mostly food rests in a bin bag) is dropped into a volcanic lake.
The lake reacts with violent lava fountaining activity, presumably in part due to steam produced from the organic matter. The lava lake at Erta Ale has persisted for many years and contains relatively fluid basaltic lava. Only few volcanoes have such lakes.
