Video of a slow moving lava flow
in Kīlauea Volcano's lower East Rift Zone, taken May 20, 2018, at around 2:31 AM HST. The flow is ~3 m (9 ft) high. The HVO scientist mapping the flow is about ~15 m (50 ft) away from the flow front. The audio is the sound of burning vegetation and the call of coqui frogs.
