Hawaii Volcano Observatory (HVO) geologists walk over the surface of a lava flow from the Kilauea Volcano to track surface breakouts near the village of Pahoa, Hawaii October 22, 2014.  The lava began flowing from the Kilauea Volcano on June 27 and as of October 24 the flow front was 0.7 miles (1.2 km) from Pahoa Village Road, according to the U.S. Geological Survey.  About 4,000 people overall live in the residential communities that the lava is approaching. Picture taken October 22, 2014.
