Lava from the ongoing eruption at the Mauna Loa volcano is just miles away from a crucial highway on Hawaii's Big Island. But despite the inconvenience of shutting down the highway, it's unlikely any attempts will be made to redirect the lava flow, experts say.

But despite the inconvenience of shutting down the highway, it's unlikely any attempts will be made to redirect the lava flow, experts say.according to an alert from the US Geological Survey.
Lava's "tendency to flow is extremely temperature-sensitive," Paul Segall, a professor of geophysics at Stanford University who researches earthquakes and volcanoes, told CNN. This makes it "somewhat unpredictable."Additionally, although different countries have tried in the past to redirect their flows, their efforts have mostly been expensive failures. "The history is not successful," Segall said.
Some efforts to combat volcano flows have succeeded despite the odds. In 1973, for instance, the Eldfell volcanic eruption triggered a months-long crisis for the small Iceland island of Heimaey. Massive amounts of seawater were sprayed onto the lava to cool it down, which helped prevent the lava from closing off the island's vital harbor.
For Maile, the eruption of Mauna Loa is especially resonant because of its timing. The volcano erupted on November 28th, Hawaiian Independence Day, which commemorates the signing of the Anglo-Franco Proclamation of 1843 which recognized Hawaii as a sovereign kingdom.
