Lava that has entered a rural Hawaii town has been described as a disaster in slow motion. After months of creeping through uninhabited areas of the Big Island, it reached Pahoa this week, crossing a residential street, burning down a garden shed and inching toward homes and a main road that goes through downtown.
The lava is from Kilauea, one of the most active volcanos in the world. It has been actively erupting since 1983.
HOW PREDICTABLE IS ITS PATH?
Scientists from the U.S. Geological Survey's Hawaiian Volcano Observatory have the tools to monitor active volcanos to determine if an eruption is imminent and forecast the path of a lava flow.
But lava is still a natural phenomenon, and much like a hurricane, some uncertainty remains.
The Big Island's topography contributes to deviations in the lava's route, said volcanologist Loyc Vanderkluysen, an assistant professor at Drexel University in Philadelphia who earned a doctorate degree from the University of Hawaii.
