“Lava flows in the summit region are visible from Kona. Winds may carry volcanic gas and possibly fine ash and Pele’s hair (a type of volcanic glass) downwind”, said the Hawaiian Volcano Observatory (HVO).

Lava flows are not currently a danger to residents they added, due to the fact they are restricted to the vicinity of the summit caldera. As a precaution though, the alert level has been raised from ‘advisory’ to ‘warning’ by officials on the island.

“Based on past events, the early stages of a Mauna Loa eruption can be very dynamic and the location and advance of lava flows can change rapidly”, warned the HVO.
