PAHOA, HAWAII - OCTOBER 26:  In this handout provided by the U.S. Geological Survey (USGS), a HVO geologist maps the margin of the June 27th lava flow in the open field below Apa'a Street and Cemetery Road on October 26, 2014 in Pahoa, Hawaii.  Scientists of the Hawaiian Volcano Observatory conducted ground and air observations of the lava flow from the Kilauea Volcano and determined that it was 510 meters (560 yards) upslope from Pa-hoa Village Road and the flow width was about 50 meters (55 yards) at the leading edge. Molten rock from the flow is inching its way towards homes in the town of Pahoa on Hawaii's Big Island where close to a thousand people live.  (Photo by USGS via Getty Images)
