Fissure

A cinder-and-spatter cone is building at fissure 8 as the cone continues to feed a lava flow that reaches the ocean at Kapoho during ongoing eruptions of the Kilauea Volcano in Hawaii.

Steam rises from cracks in the road shortly before a fissure opened up on Kaupili Street in the Leilani Estates subdivision, May 4, 2018, in Pahoa, Hawaii, in this image released by the U.S. Geological Survey.

After Miller's Dale Junction, the main Derby-Manchester line crosses the Wye for the last time and turns north-west up Great Rocks Dale, a natural fissure several miles long.
