And you thought your job was tough? In this photo a #geologist at the #Hawaiian Volcano Observatory shields his face from the intense heat as he takes a sample of active lava on the Kahaualeʻa 2 flow. The chemistry of the #lava is analyzed through time and used to study changes in the magmatic system.
