Disposal of organic waste in Erta Ale Volcano lava lake causes violent eruption

Incineration of organic waste in Erta Ale Volcanoes lava lake as simulation of what would happen if a person would fall into the lava lake (since both are organic and contain water and would thus be expected to trigger similar response).
It is frequently discussed whether it is possible to sink in lava. Due to its high density, a person would generally be expected to remain on the surface. Indeed it is possible to briefly walk on certain types of lava if professional heat-protective clothing is worn (do not try yourself). However, the video shows that falling from a height, a large object and thus also a person would be able to penetrate the crust of the lake and submerge in it. The test was performed with a box of camp waste (largely food rests) in a cardboard box. Estimated weight 30kg, Size 60x60x60cm. Fall height, about 80m. The lake reacts with violent lava fountaining activity, presumably in part due to steam produced from the organic matter.
