A fissure from Hawaii’s erupting volcano Kilauea reopened on Monday, spewing fountains of lava 200 feet into the air and creating a phenomenon called “Pele’s hair”—thin strands of volcanic glass that can be harmful if touched or inhaled, according to the United States Geological Survey.

Volcanic glass from the fissure is blowing downwind, where the USGS has urged people “to minimize exposure to these volcanic particles, which can cause skin and eye irritation similar to volcanic ash.” Residents should also avoid touching Pele’s hair, Hawaii County Civil Defense said.
