A "smiling" volcano has gone viral.
Hawaii's Kilauea volcano has been actively erupting since 1983, and it's one of the most active volcanoes in the world, according to the U.S. Geological Survey (USGS). But the volcano received more attention recently when the volcano's lava formed what looks like a smiley face.
The smiley face appeared in a lava lake crater on the west flank of Pu'u 'O'o, on Kilauea's East Rift Zone, according to Janet Babb, a geologist with the USGS' Hawaiian Volcano Observatory.
