This long thin, strand of volcanic glass is called Pele's hair. Named for Pele, the Hawaiian goddess of fire, Pele's hair is formed from lava fountains and rapidly moving lava flows. This strand of Pele’s hair was found on Kupono Street in Leilani Estates, Hawaii, during the Kīlauea volcano eruption.

At 9:06 a.m. HST, 5/11/18, an ash plume rose from the Overlook crater at Kīlauea's summit. Similar to recent plumes, this event was likely caused by a rockfall from the crater's steep walls.

Ash column rises from the Overlook crater at the summit of Kīlauea Volcano. HVO's interpretation is that the explosion was triggered by a rockfall from the steep walls of Overlook crater. The photograph was taken 5/9/18 at 8:29 a.m. HST from the Jaggar Museum overlook.

HVO geologist measured a temperature of 103 degrees C (218 degree F) at a crack along Nohea Street, Leilani Estates. The asphalt road was describes as "mushy" from the heat.

Scientists are collecting core samples from the Great Dismal Swamp in Virginia to understand natural conditions before centuries of ditching, draining and harvesting. This is a collaborative project between the USGS and the Great Dismal Swamp National Wildlife Refuge.
