Photographer Carsten Peter tests the thermal suit that Sims used to get close to the lava lake. “It can protect you from the radiant heat, but if you get hit with a lava splatter, the force will likely kill you,” he says. For 30 years Peter has explored volcanoes around the world. “Seeing at close range the primal forces that shaped the planet can be hypnotic. You cannot allow yourself to fall under a volcano’s spell, especially one as unpredictable as Nyiragongo. That can be a fatal mistake.”

This caught my attention in National Geographic.
