Lava continued to flow from Hawaii’s Kilauea volcano in lower Puna on May 21. Several volcanic fissures reactivated after an explosive eruption at the summit of Kilauea on May 17, causing a continuous lava flow.
Hawaii County Civil Defense Agency warned residents in the East Rift Zone of Kilauea to be mindful of volcanic gas, which it said was especially dangerous for elderly people, children and those with respiratory issues.
The USGS said it was not yet possible to tell if the fissures would become long-term active vents or would only remain active for a brief period of time before waning.
