PAHOA, Hawaii - Lava from Kilauea volcano has forced Shawn Heard to move her house once already, back in the 1980s. She's at peace with the possibility of eventually having to do so again. Heard lives just miles from a cluster of homes that is being threatened by a lava flow inching its way down the lush, rain forest-like slopes of Kilauea. She knows lava could one day get to her house.
