Volcanic Ash Cloud Disrupts Flights

June 29, 2011

An ash cloud from a Chilean volcano is disrupting air travel in Australia and New Zealand.

From CNN:

“Volcanic ash from the eruption of the Puyehue Cordon Caulle volcano in Chile continues to cause flight disruptions to the Qantas network,” the airline said in a statement.

“At Qantas safety is our first priority and a number of flights have been canceled or rerouted to avoid the volcanic ash cloud.”

Qantas and Jetstar suspended Wednesday flights to and from Queenstown, Christchurch and Wellington.

Qantas flights between Sydney and Buenos Aires are delayed.

Volcano Ash Cloud Moves Over UK

May 24, 2011

A cloud of ash from Iceland’s Grimsvotn volcano is spreading towards central Europe, forcing airlines in Britain to cancel hundreds of flights for the second time in little more than a year.

From CNN:

The ash cloud began to reach London’s Heathrow airport — the world’s busiest international air travel hub — around lunchtime, a computer model indicated. The European air traffic control organization Eurocontrol reported about 500 flights in British airspace would be canceled Tuesday, roughly double the number expected earlier in the day.

The ash cloud was projected to cover all of British airspace by early Wednesday morning and will be densest over Scotland, Northern Ireland and northern England, according to Britain’s weather agency, the Met Office.

Ash From Eyjafjallajokull Volcano Grounds Flights Again

May 5, 2010

Ash from the Eyjafjallajokull volcano in Iceland has shut down airports in England and Ireland again today, causing disruptions to hundreds of passengers.

From CNN:

Glasgow airport in Scotland closed at 7 a.m. (2 a.m. ET), and both main airports in Belfast, Northern Ireland, were due to close at 1 p.m. (8 a.m. ET), Britain’s Civil Aviation Authority said. The restrictions were due to last until 7 p.m. (2 p.m. ET) and included nine other airports in Scotland and Northern Ireland, the CAA said.

In Ireland, the airports in Dublin and three other cities were closed to flights “until further notice,” the Irish Aviation Authority said. The IAA lifted earlier restrictions on other airports, including Shannon, but said they could be reimposed later.

Planes Flying Again in Europe

April 22, 2010

Flights across Europe are expected to return to normal today, seven days after ash from an Icelandic volcano forced the shutdown of airspace and stranded thousands of passengers around the world.

From CNN:

The mood among passengers was one of cautious optimism. After days of endless waiting, many reserved their celebrations for when they were airborne.

“I think when we land down in America, then we’ll know we’re there. But at the minute, we’re a bit cautious,” said Georgina Evett.

She was part of a group trying to fly from Manchester, England, to Florida for a world cheerleading championship this week.

Manchester Airport was among many where flights are now taking off and landing.

The closure of so much European airspace for nearly a week left untold numbers of travelers stranded, and it’s not clear how long it will take to get everyone home.

Philippines Volcano Shakes Once Again

December 16, 2009

More than 30,000 people have fled their homes ahead of an expected eruption of the Mayon volcano in the central Philippines.

From CNN:

Philippine authorities have said a large-scale eruption of the 2,464-meter (8,077-foot) peak is imminent, and have begun trying to evacuate about 50,000 people living around the nation’s most active volcano.

Gwendolyn Pang, the secretary-general of the Philippine Red Cross, said the ground around the mountain shook several times Wednesday. Emergency workers have so far evacuated 30,751 people, with 21 centers set up to take in the evacuees, she said.

People in surrounding Albay province have flocked to town centers to catch a glimpse of glowing lava cascading down the slopes of Mayon since the mountain began oozing fiery lava and belching clouds of ash this week.

The Philippine Institute of Volcanology and Seismology raised its alert level for the Mayon volcano Monday night, warning that a full-scale eruption could occur “within weeks to days.” The volcano, about 500 kilometers (310 miles) south of the Philippine capital Manila, has gone off 49 times since the first documented eruption in 1616.

Earthquake Rattles Island of Hawaii

April 14, 2009

An earthquake measuring a magnitude of 5.1 has struck the island of Hawaii.

From KHNL:

The quake’s epicenter was located 27 miles south of the city of Hilo and about 9 miles south of the town of Volcano.

The earthquake was felt at 12:44 Tuesday. The exact coordinates of the quake are 19.328°N, 155.210°W.

It is unknown if the earthquake poses any tsunami threat at this time.

Undersea Volcano Erupts in Tonga

March 19, 2009

Scientists are inspecting an undersea volcano that has been erupting for days near Tonga.

The volcano is shooting smoke, steam and ash thousands of feet into the sky above the South Pacific ocean.

From the Associated Press:

Authorities said Thursday the eruption does not pose any danger to islanders at this stage, and there have been no reports of fish or other animals being affected.

Spectacular columns are spewing out of the sea about 6 miles from the southwest coast off the main island of Tongatapu — an area where up to 36 undersea volcanoes are clustered, geologists said.

Trade winds continued to blow gas and steam away from the island Thursday.

No warnings yet
Tonga’s police deputy commander Taniela Faletau said coastal villages close to the roiling ocean site were not yet at risk and that no warnings had been issued.

Police were waiting for a government team of officials and scientists to survey the area and report on their observations before taking any action.

Coastal residents said the steam and ash column first appeared on Monday morning, after a series of sharp earthquakes were felt in the capital, Nuku’alofa.

Volcano Set to Erupt in Alaska

February 4, 2009

Mount Redoubt is ready to blow, but Alaskans appear to be taking it in stride.

We may have earthquakes in California, but I’m glad I’m no where near an active volcano!

From CNN:

“I looked up and there was a huge cloud,” recalls Debbie Adamson. “It looked like a Disney movie, billowing up in the sky.”

But what goes up must come down, and so it was with the ash from the eruption. On and off for five months Redoubt dropped ash on this community of about 7,500 people.

“It fell straight down. That was cool,” says Sandy Campbell, who took off work the first day of the eruption but was back out on the streets by that evening. “The eruption was the night of the Christmas party, we didn’t miss that.”

Campbell and Adamson have been pals for years. They live in Kenai, Alaska, just across Cook Inlet from Mount Redoubt.

In the summer months they’ll be out fishing for red salmon together on the banks of the Kenai River, but on this bitter cold February day they are warming themselves with hot tea among the mounted moose heads and stuffed king salmon at Louise’s restaurant on the main drag in town.

When Redoubt blew in 1989, the ash coated everything in town — making it difficult to breathe, hard on cars and nearly impossible to clean up. Both women have bought paper masks to wear, as they did last time.

“All of us did. We wore them wherever we went,” says Adamson “That’s ground rock. The body doesn’t eliminate it, it stays in your lungs.”

They have fresh air filters for their cars. Some here in town claim the best way to protect your car is to put a pair of pantyhose over the air intake on the car’s engine, but the ladies remember what happened last time.

“One guy forgot to take the pantyhose off,” recalls Campbell, who says a few weeks after the eruption the man’s car stopped running. “They found a bunch of wadded up pantyhose in his engine.”

Campbell’s first experience with a volcano came in 1980, when her parents were picking her up from college in Oregon. They drove right into the ash from Mount St. Helens, but she knows this is much different. The Mount St. Helens explosion killed 57 people. With Redoubt the impact will probably be more of a nuisance than truly dangerous

“Its kind of exciting,” she says. “But we’re not in imminent danger.”

It’s all part of being an Alaskan, they say.

“It’s a hearty bunch of people up here,” says Adamson. “It was exciting and a wonderful thing to experience because most people are never going to see something like that.”

Like seeing moose as they graze along the roads, or going out for a cup of tea when the temperature is 10 below zero, having a volcano in your back yard seems like part of life in a state known as “The Last Frontier.”

Has a Volcano Awakened at Yellowstone?

January 10, 2009

Hundreds of small earthquakes at Yellowstone National Park over the past few weeks have been a reminder for some people that underneath the park’s word famous geysers lurks one of the world’s biggest volcanoes.

From the Associated Press:

In the ancient past, the volcano has erupted 1,000 times more powerfully than the 1980 blast at Mount St. Helens, hurling ash as far away as Louisiana. No eruption that big has occurred while humans have walked the earth, however, and geologists say even a minor lava flow is extremely unlikely any time soon.

Some observers are nonetheless warning of imminent catastrophe.

“To those of us who have been following these events, we know that something is brewing, especially considering that Yellowstone is over 40,000 years overdue for a major eruption,” warned a posting on the online disaster forum

Another Web site contained a page entitled “Yellowstone Warning” that encouraged “everyone to leave Yellowstone National Park for 100 miles around the volcano caldera because of the danger in poisonous gasses that can escape from the hundreds of recent earthquakes.”

That site, which carried the U.S. Geological Survey logo, has since been taken down.

“A casual observer would be led to believe that was an official source,” Yellowstone spokesman Al Nash said, pointing out that the Yellowstone Volcano Observatory, which monitors the park for seismic activity, hasn’t changed the volcano’s alert level from “normal.”

Working with the Geological Survey, Nash issued a news release Thursday, saying no evacuation had been ordered.

Jessica Robertson, a Geological Survey spokeswoman in Reston, Va., said the Web page violated the USGS trademark and that the agency’s attorneys were investigating whether a federal offense was committed.

Phone and e-mail messages left with the contact named on the Web site weren’t returned Thursday.

Earthquakes are hardly unusual in Yellowstone. Hundreds occur in the park every year. Earthquake “swarms” like the recent activity also aren’t uncommon, although the 900 or so quakes that began Dec. 26 and significantly tapered off about a week later appear to have been the most energetic swarm in more than 20 years.

The most powerful temblor was magnitude 3.9, just short of being able to cause moderate damage. The vast majority of quakes were too weak to be felt by people.
