An AP investigation revealed the problem is larger than at first thought.
Scientists said internal conditions at Kilauea are changing in a way that could lead to an explosive eruption.
Lava flows from Kilauea, one of the earth’s most active volcanos, have already destroyed 36 structures in the Puna District of the Big Island.
After a brief pause in volcanic activity, two more lava fissures Tuesday threatened Leilani Estates and Lanipuna Gardens communities.
The people here are largely self-sufficient and understand the hazards of their location.
UPDATED: Hundreds of residents of the Leilani Estates subdivision were allowed to briefly return to their homes to gather possessions.
UDATED: A magnitude 6.9 quake hit Friday as more than 1,700 residents faced evacuation orders.
UPDATED: The Leilani Estates subdivision is at greatest risk, but scientists say new vents and outbreaks could occur.
It may have already gone under the highway to the viewing area, and Hawaii County is making preparations for a possible eruption.
