USA, Hawaii: Lava is Flowing Away from Puna Geothermal Venture

Map as of 6:45 a.m. HST, May 15, shows the location of the 'a'ā lava flow spreading from fissure 17; the flow front at the time is shown by the small red circle with label. The flow is following a path of steepest descent (blue line), immediately south of the 1955 'a'ā flow boundary. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Ash emission from the Kilauea summit vent will likely be variable with periods of increased and decreased intensity depending on the occurrence of rockfalls into the vent and other changes within the vent.

At any time, activity may become more explosive, increasing the intensity of ash production and producing ballistic projectiles near the vent.
