To understand more about Kilauea volcano's threat from a slow-moving lava flow in a Hawaiian town, affected traders are meeting civil defense officials.

The meeting was fixed for Wednesday in the town of Pahoa on the Big Island. Since 1983, Kilauea has been constantly erupting and scientists have started worrying when a new lava flow moved within a mile of a subdivision last week.

The flow comes out from a vent at Kilauea's Puu Oo crater in late June and from that time it has moved about nine miles.

The flow had moved about 460 yards between Tuesday and Wednesday morning, according to a blog from scientists at the U. S.

Late last week, an emergency order has been signed by Gov. Neil Abercrombie for Hawaii County and no families have been yet informed to vacate the place but they know there is a possibility that they can be asked to vacate it.

The flow has slowed and started moving parallel to the Kaohe Homesteads. Researchers say that the flow could still move slowly into the subdivision.

On Tuesday, County Mayor Billy Kenoi told community members that there is also possibility that lava will cross key roads within weeks, so researchers are preparing for it. The country is also planning alternate routes.

The Hawaiian Volcano Observatory said on Wednesday that lava flow has increased 460 yards since the previous morning.

The lava is moving slowly through thick forest, setting on fire trees and creating smoke plumes. It is seen only from the air not like previous flows that travelers could observe drop in the ocean from coastal viewing areas.

Residents have been warned about the lava because there is possibility that lava might cover part of a highway that could isolate about 8,000 people.
