Emergency authorities battling lava flows and gas erupting from Hawaii's Kilauea volcano have warned some residents to "go now" as a new fissure opened and more structures were destroyed.
Kilauea has destroyed 26 homes and forced 1700 people to leave their residences since it erupted on Thursday, spewing lava and toxic gas from volcanic vents in a small area of Hawaii's Big Island.
A new fissure opened on Sunday night in the Leilani Estates area about 19km from the volcano, prompting a mobile phone alert for residents to leave homes to avoid sulfur dioxide gas, which can be life threatening at high levels.
So far no fatalities or major injuries have been reported from the volcano, according to the Hawaii County Civil Defence Agency.
Evacuees from Leilani Estates were allowed to return for pets, medications and to check property on Sunday.
As of 3.30am local time on Monday, 161 people were housed at two evacuation centres on the island, the Hawaii Civil Defence Agency said.
