But despite the inconvenience of shutting down the highway, it’s unlikely any attempts will be made to redirect the lava flow, experts say.“There are many variables at play and both the direction and timing of flow advances are expected to change over periods of hours to days, making it difficult to estimate when or if the flow will impact Daniel K. Inouye Highway,” wrote the agency in its update.In the past decades, workers have used bulldozers to construct huge earthen walls to redirect after eruptions like that of Mount Etna in Sicily.And in 1935, Thomas Jaggar, founder of the Hawaiian Volcano Observatory, called on the US Army Air Corps to bomb the source of lava flowing from Mauna Loa, which was headed towards the Wailuku River, according to the U.S. Geological Service.“Instead of containing lava flowing from Mauna Loa, the US military should clean up their own mess at Pōhakuloa Training Area, and contain ongoing jet fuel and ‘forever chemical’ spills at Red Hill.”In the meantime, Hawaiian officials say they have a plan to shut down the highway if the lava gets close enough to become dangerous."
