Residents were advised to evacuate by Friday afternoon or get arrested, and emergency responders said they had no plans to rescue anyone from the evacuated areas past the deadline, the agency said.
More than 400 power poles and other equipment have been destroyed by the encroaching lava, Hawaii Electric Light Co. said. "They are not only putting themselves into potentially life-threatening situations, but we can't completely lock gates or erect impassable barricades in areas where people have only one way out - these are the routes loiterers are using to gain up-close access". They stopped to inquire of their situation, and then when asked, airlifted them to a safe place.
Officials say birds and wildlife are OK in areas upwind of the lava flow.
There are no immediate reports or damage, injuries or fatalities from the quake, which was recorded at around 3.30pm GMT. The seven individuals will have to appear in court, Hawaii officials said.
Lava from a fissure near the volcano entered Kapoho Bay late Sunday or early Monday, forcing billowing clouds of steam into the atmosphere as hot lava hit the cool water of the Pacific Ocean.
These were new risks geologists warned of on Tuesday (May 22) as Kilauea's 19-day eruption showed no sign of easing, with repeated explosions at its summit and fountains of lava up to 160 feet (50 m) from giant cracks or fissures on its flank.
In its report, the US Air Force said: "Modern aerial bombing has a substantial probability of success for diversion of lava from most expected types of eruptions on Mauna Loa's Northeast Rift Zone, if Hilo is threatened and if Air Force assistance is requested".
The resulting steam from the lava creates a anxious mixture that is leaking into the atmosphere, with hydrochloric acid and volcanic gas posing threats to anyone nearby, acting as an irritant to skin, eyes and lungs.
Lava erupts in May from a fissure in the Leilani Estates neighbourhood.
"These remnant and sub-populations of wildlife may no longer persist, rapidly decline, or become further fragmented and/or contract in range", said Steve Bergfeld, the Branch Manager of the DLNR Division of Forestry and Wildlife, in the release.
