Abstract
Most of the "floating islands" are fragments of the surrounding wall fallen into the lake. Others are thickened portions of crust or small cinder and spatter cones. Perret attributes the flotation to the combined effects of the surface tension of the lava, buoyancy of a rising column of lava with gas beneath, and evolution of gas from the island itself owing to chemical reactions. He describes the behavior of one particular island, during August 1911, and notes that rise and fall of the liquid lava does not necessarily raise or lower the island.
