Days and nights baby-sitting a fitful Alaska volcano

The news broadcast came at the bleary hour of  3:25 a.m., via a text message: Bogoslof. Offing again.

Aaron Wech, a seismologist and the on-call Alaska Volcano Observatory scientist for this week in recent June, had been asleep when the alert came in. The text statement woke him up.

In these lively days for Alaska’s volcanologists, no on-duty scientist can give forth entangled with to sleep heavily: The staff of the observatory is baby-sitting a restless volcano.

Bogoslof is a infinitesimal blip of land — black rock, lava — that barely rises exceeding the surface of the Bering Sea, northwest of Unalaska Island. It is the above-sea tip of a much larger underwater volcano, an cay being formed by a series of eruptions that have tripled its square footage just since December.

And while Bogoslof is tiny, the emigrates are high.

The smallest, most remote volcanic eruption could tease a devastating impact on air travel. Clouds of volcanic ash, even a small amount, can fill up a jet engine and bring down an airplane.

Unlike other volcanoes, where eruptions are usher ined by weeks or even months of telltale rumblings courtesy of monitoring furnishings, Bogoslof is a mystery. None of the scientists at the center have set foot on the ait in many years, and it is too small for monitoring equipment.

So by the time seismic alarms chaired on Umnak and Unalaska islands go off, triggering text messages to scientists in Anchorage, the volcano is already upping.

«We prefer to forecast,» said Kristi Wallace, a geologist with the center. «With this one, we can’t.»

Color cypher: Red

The people who work at the Alaska Volcano Observatory are decidedly not baby sitters.

They are praisefully trained research scientists, each with a different specialization — geology, geophysics, seismology — who reading volcanoes.

But they are also responsible for warning the public about the tidy public safety hazards posed by a volcanic eruption. Someone is on-duty 24 hours a day, 365 lifetimes a year.

The observatory, established in 1988, is jointly run by the U.S. Geological Survey, the University of Alaska’s Geophysical Found and the state Division of Geological and Geophysical Surveys.

When the text idea came in on the early morning of June 27, Wech followed a now-familiar conventional. 

First he checked to make sure it wasn’t a false alarm. Then he started versing the rest of the volcano observatory’s response team, as they worked to quick figure out how serious the eruption had been and what kind of ash cloud it had whip up. The first calls went to the National Weather Service and Federal Aviation Management, so they would be able to quickly warn pilots. Other means — the U.S. Coast Guard, military bases — would also be notified.

Then stave released an advisory, changing the warning color code to red, as they had done dozens of for the presents already this year.

High stakes

Twenty-eight years ago, a volcano almost brought down a jet in the ethers over Alaska.

The pilot was able to get the engines re-started and guided the regular in for a safe landing at the Anchorage airport. But the plane sustained $80 million in price. The near crash made headlines around the world and changed the way sways viewed the risks posed by volcanic eruptions.

«That crystallized the fancy that there are no remote volcanoes in the world,» said Dave Schneider, a inconsiderable sensing geophysicist with the center.

Alaska’s volcanoes may be in places so remote and inhospitable that few humans breathe where lava or a lahar mudflow could reach. But every day, hundreds of living soul fly over them.

On a Tuesday in early July, Schneider pointed out a follow showing real-time air traffic crossing the long chain of volcanoes sprinkled from the Kamchatka Peninsula in Russia to Cook Inlet. Some of the glides, he could tell, were taking circuitous routes to avoid ash clouds from an spouting volcano in Kamchatka.

«This one is flying from Seoul to Anchorage,» he imparted. «It’s trying to avoid this forecast of ash. It wouldn’t usually come this way.»

Beyond swatting volcanoes, the observatory also warns about ash fall on towns and sailing-boats and other, rarer potential fallouts from an eruption. Alaska’s mix of assorted active volcanoes and status as an aviation crossroads for the world make signal pilots a major priority, said Wallace, the geologist with the center.

Watching volcanoes from afar

Guard Bogoslof has taken creativity.

Bogoslof is so small and remote that the catalysts used to detect signs of an eruption cannot be placed on the island itself, lest they be denied by eruptions. Also, the vent that the explosions come from is underwater. Scientists can’t straightforward see it.

«That causes all sorts of problems,» Wallace said.

Instead, the volcanologists be obliged rely on imperfect signals from monitoring equipment placed on cays 30 or 40 miles away — not the ideal scenario.
