Steam, lava emissions and rockfalls following the eruption of Hawaii's Kilauea volcano triggers a "voluntary evacuation" warning.
Up to 10,000 people have been asked to leave their homes on Hawaii's Big Island following the eruption of the Kilauea volcano on Thursday that came after a series of recent earthquakes.
"Department of Public Works reports steam and lava emissions from a crack in Leilani Subdivision in the area of Mohala Street," the Hawaii County Civil Defense Agency wrote in a Facebook post.
An official added the zone is home to about 10,000 people, and was a "voluntary evacuation."
US Geological Survey authorities of the Hawaiian Volcano Observatory unit were both on the ground and headed into the air to assess the eruption, which began around 4:45 pm local time (0245 GMT).
At 10:30 am a 5.0 magnitude earthquake south of the Puu Oo volcano cone triggered rockfalls and potential collapse into a crater on the volcano, according to USGS.
"A short-lived plume of ash produced by this event lofted skyward and is continuing to dissipate as it drifts southwest from Puu Oo," an advisory from USGS said, warning that "anyone downwind may experience a dusting of ash."
Authorities said hazards linked to the ongoing eruptions could include "potentially lethal concentrations of sulfur dioxide gas" in the zone as well as methane blasts that could propel large rocks and debris in adjacent forested areas.
I urge residents in Leilani Estates and the surrounding areas to follow instructions from the County of Hawai‘i’s Civil Defense Agency. Please be alert and prepare now to keep your family safe. @USGSVolcanoes #Kilauea— Governor David Ige (@GovHawaii) May 4, 2018
Governor David Ige had activated the archipelago state's National Guard troops, and told residents to pay heed to warnings from the Civil Defense Agency.
"Please be alert and prepare now to keep your family safe," Ige wrote on Twitter.
A local community center was open to residents impacted by the threat, Hawaii's emergency management agency said.
