The East Pond vent, on the eastern side of the Pu‘u ‘Ō‘ō crater, has hosted a small lava pond for the last couple of years. Sloshing and weak spattering on the pond surface frequently ejects small pieces of spatter and Pele’s tears. The small wooden boxes, seen in this photo on the edge of the vent just below the area of strongest spattering, are used to collect these stray pieces of lava. Chemical analyses of the spatter and tears allows us to study the evolution of the lava to better understand the eruption.
