Lava from the continuing eruption on the Mauna Loa volcano is simply miles away from a vital freeway on Hawaii’s Massive Island. However regardless of the inconvenience of shutting down the freeway, it’s unlikely any makes an attempt can be made to redirect the lava stream, consultants say.
As of Saturday morning, the lava was simply 2.5 miles from the Daniel Ok. Inouye Freeway, based on an alert from the US Geological Survey. It had been shifting round 40 toes per hour over the past 24 hours, the company says.
However predicting if, or when, the lava may hit the freeway, which connects the west and east of the island, is tough.
“There are a lot of variables at play and each the route and timing of stream advances are anticipated to alter over intervals of hours to days, making it tough to estimate when or if the stream will impression Daniel Ok. Inouye Freeway,” wrote the company in its replace.
That is a part of the issue with makes an attempt to redirect the lava stream: lava is unpredictable, and it’s exhausting to inform the place it would go subsequent.
Lava’s “tendency to stream is extraordinarily temperature-sensitive,” Paul Segall, a professor of geophysics at Stanford College who researches earthquakes and volcanoes, instructed CNN. This makes it “considerably unpredictable.”
It’s exhausting to say at this level whether or not the lava will even attain the freeway, Segall defined.
Moreover, though totally different international locations have tried up to now to redirect their flows, their efforts have principally been costly failures. “The historical past shouldn’t be profitable,” Segall mentioned.
Previously a long time, staff have used bulldozers to assemble big earthen partitions to redirect after eruptions like that of Mount Etna in Sicily.
And in 1935, Thomas Jaggar, founding father of the Hawaiian Volcano Observatory, known as on the US Military Air Corps to bomb the supply of lava flowing from Mauna Loa, which was headed in the direction of the Wailuku River, based on the U.S. Geological Service. The military dropped two 600-pound bombs, however they missed their goal and had minimal impact on the lava flows.
Some efforts to fight volcano flows have succeeded regardless of the chances. In 1973, for example, the Eldfell volcanic eruption triggered a months-long disaster for the small Iceland island of Heimaey. Large quantities of seawater have been sprayed onto the lava to chill it down, which helped stop the lava from closing off the island’s important harbor.
Segall additionally mentioned that more and more, scientists and residents of Hawaii alike view the lava stream as a pure phenomenon – not one thing that must be disrupted.
“I feel there’s a good quantity of sentiment in Hawaii that you just don’t mess with Pele,” he mentioned, referring to the Hawaiian goddess of fireside. “That it is a pure course of.”
Uahikea Maile, an assistant professor of indigenous politics on the College of Toronto, echoed this sentiment.
For Maile, the eruption of Mauna Loa is particularly resonant due to its timing. The volcano erupted on November twenty eighth, Hawaiian Independence Day, which commemorates the signing of the Anglo-Franco Proclamation of 1843 which acknowledged Hawaii as a sovereign kingdom.
“Mauna Loa is erupting on Lā Kūʻokoʻa, Hawaiian Independence Day. Settler society sees her as a harmful risk for containment,” Maile wrote on Twitter. “That is true too for Hawaiian sovereignty. However we’re irrepressible. It could be harmful, however it creates life to face on for generations to return.”
“Like Mauna Loa, Hawaiian sovereignty is seen as one thing that must be contained that must be suppressed,” Maile instructed CNN.
He famous that Hawaii itself was created on account of volcanic eruptions. With out volcanoes, there can be no Hawaii.
And somewhat than making an attempt to interrupt pure phenomena like lava flows, he steered that people ought to be extra aware of their very own impression on Hawaii. He highlighted petroleum contamination linked to Navy bases on Hawaii, in addition to the environmental destruction brought on by tourism and the November spill of “endlessly chemical compounds” at Hawaii’s Purple Hill Naval Facility.
“These are types of unnatural environmental destruction and volatility that ought to be thought of extra of a precedence than the bombing of lava stream,” Maile mentioned. “As an alternative of containing lava flowing from Mauna Loa, the US army ought to clear up their very own mess at Pōhakuloa Coaching Space, and include ongoing jet gas and ‘endlessly chemical’ spills at Purple Hill.”
Within the meantime, Hawaiian officers say they’ve a plan to close down the freeway if the lava will get shut sufficient to turn out to be harmful.
