Officials in Hawaii have a message for the many people flocking to see the world's largest active volcano ooze molten rock: You may do so, safely, from a newly developed route that won't get you ticketed.
Mauna Loa on Hawaii's Big Island has been erupting for days, with lava shooting to heights of up to 148 feet on Tuesday.
And although the rare sight has been keeping officials and residents on guard for any possible hazards, local authorities have developed a way -- quite literally -- for visitors to see the eruptions.
A traffic hazard safety route is now accessible through Saddle Road, also known as Daniel K. Inouye Highway, according to the Hawaii County Civil Defense Agency.
The one-way route "will provide safe viewing of lava flows," the agency said Thursday, declaring that parking on the highway was putting motorists at risk of traffic citations and vehicles towed.
Mauna Loa's eruption earlier this week for the first time since 1984 has led to concerns related not only to the lava's impact on the island's main highway but also health hazards stemming from possible toxic gases being released into the air.
As of Thursday afternoon, Mauna Loa's lava was just over 3 miles away from Saddle Road, the fastest route linking the west and east coasts of Big Island, according to the US Geological Survey. But the lava's flow rate has been slowing down and spreading out, sparing people and property from immediate threat.
"Advance rates may be highly variable over the coming days and weeks due to the way lava is emplaced on flat ground," the geological survey said in an update Thursday.
Still, the simultaneous eruptions of Mauna Loa and neighboring volcano Kilauea, which has been erupting for more than a year, could possibly put people at risk of inhaling air that's been compromised, state health officials have warned.
Residents and visitors can expect "vog conditions, ash in the air, and levels of sulfur dioxide to increase and fluctuate in various areas of the state," the Hawaii health department said.
Plus, a combination of volcanic gas, fine ash and Pele's Hair -- which are strands of volcanic glass -- could be carried downwind, the geological survey said.
And the plumes of dark clouds billowing out of the volcanoes are not smoke -- they're "volcanic gases, which are acid gases. You don't want to breathe them in," said volcanologist Jess Phoenix.
"You're talking hydrogen fluoride, hydrogen sulfide, carbon dioxide. These are all gases that are really not fun for average folks to breathe in, let alone if you have any sort of respiratory issue," Phoenix said.
"So the Hawaiian Civil Defense Authority and the US Geological Survey will closely monitor the volcanic smog ... and they will let any communities affected know well in advance if people with respiratory issues should stay inside."
Children, the elderly and those with respiratory conditions should reduce outdoor activities that cause heavy breathing and reduce exposure by staying indoors and closing windows and doors if vog conditions develop, the health department said.
While evacuation orders have not been issued, Hawaii Gov. David Ige said he signed an emergency proclamation as a "proactive" measure.
The governor acknowledged Wednesday the potential for air hazards and said officials are tracking air quality monitors across the island.
"The concern is about dangerous gases from the fissures. And the most dangerous is sulfur dioxide," Ige said. "Observing the volcano should occur at a distance. It's not safe to get up close."
Highway's closure would cause major traffic headaches
It could take at least a week until Mauna Loa's lava reaches Saddle Road due to significant reduction in the lava's flow speed.
"Advance of the largest flow slowed over the past 24 hours to a rate of about 0.025 miles per hour," the geological survey said Thursday. "However, there are many variables at play and both the direction and timing of flow advance are fluid and are expected to change over periods of hours to days."
The state's transportation department and local officials have been working on a plan to shut down the highway if the lava gets close enough to become dangerous, said Adam Weintraub, communication director for the Hawaii Emergency Management Agency.
But even with those plans in place, some drivers will still feel the burden of much longer commute.
Emmanuel Carrasco Escalante, a landscape worker, said he would then have to decide between the northside or southside coastal roadways to get from Hilo to Kona.
"It's a hassle to drive all the way around the island," he told CNN. "If the road closes, that would add almost two hours, more gas, and more miles so hopefully it (lava) doesn't cross that road."
The transportation department shared a preliminary plan for the possibility of closure. The department can provide a six-hour notice of the road's closure, Weintraub said.
"And the staff at the Hawaiian Volcano Observatory say that they can provide at least 24-48 hours advance warning if the lava appears to be threatening the roadway," he said.
And if emergencies arise during a possible highway closure, there are hospitals and first responders on each side of the island, Weintraub said.
