Lava in Hawaii flows 800 feet a day toward homes

Rural Hawaii residents are keeping a nervous eye on a lava flow that is moving 800 feet a day toward their community.
Lava from the Kilauea volcano is less than a mile from Kaohe Homesteads and could reach it in five to seven days if it continues on its current path, AP quoted geologists with the Hawaiian Volcano Observatory as saying, raising the alert level Thursday to a warning. It wasn't immediately clear how many homes could be affected.
However, the observatory said predicting a lava flow's exact path can be difficult because of subtle variations in topography, changes in lava volume and how lava enters or exits ground cracks.
