Molten lava is starting to flow toward a village on Hawaii’s Big Island where it could burn down the first home since the Kilauea volcano erupted back in the summer.

The lava had crossed a road and carpeted a cemetery on its way toward homes, according to Reuters. At 1,650 degrees Fahrenheit, it would instantly set afire any structure it came across.

A total of 50 homes were in the path of the lava, the leading edge of which is about 250 feet wide. Residents have been slowly moving out of those homes as the lava approaches.

The lava has been approaching since June 27 when the Kilaueu volcano began spewing it out. Since then, it has taken a slow march to the village of Pahoa. It stopped moving in September, but resumed a few weeks ago.

A column of black smoke currently hangs over the town as the lava makes its way slowly across the land, destroying vegetation in its wake. It destroyed an uninhabited building at one point.

The National Guard is likely to arrive eventually to prevent looting, although there have so far been no reports of that activity yet. Authorities plan to visit the affected homes to make sure everyone leaves hte area before nightfall. However, they won’t force residents to stay away.

The population of Pahoa is about 800 residents. Its businesses are at the south end of the village, and face the least threat.

The Kilauea volcano has been an active site since 1983, with its Pu’u O’o vent primarily contributing to the destruction of 180 homes in the 1980s. The last home it destroyed was in 2012.
