Hawaii volcano update: How far is lava from Kona? Is air quality affected?
Residents living in Kapoho Beach Lots and Vacationland were told to evacuate at 1.30am local time (12.30pm BST) or risk being trapped by the advancing molten rapids.
A Hawaii County Civil Defense Agency statement said: “You are at risk of being isolated due to possible lava inundation of Beach Road near Four Corners.
“At the present rate of flow, it is possible that Beach Road near Four Corners may be blocked within 4 to 6 hours.”
Kapoho is part of Puna district, an area at the southern-east tip of Big Island, where fissures have been violently erupting since May 3.
