Ash plume from underwater volcano off Tonga cancels flights and turns sea red | World news | theguardian.com

Air New Zealand and Fiji Airlines both turn flights around after Hunga Tonga-Hunga Ha’apai sends huge ash cloud kilometres into air about 65km north of capital Nuku’alofa

An underwater volcano off Tonga was spewing ash high into the air on Tuesday, causing several carriers to suspend air travel to the South Pacific island nation and turning the surrounding ocean blood red, residents and officials said.

The Hunga Tonga-Hunga Ha’apai underwater volcano, about 65km north of the capital Nuku’alofa, was sending volcanic ash up to 4,500m into the air, the Wellington Volcanic Ash Advisory Centre (VAAC) said.

Tonga residents described a spectacular sight, with the enormous plume from the volcano shooting high into the sky and a muddy discharge underwater turning areas of the sea off the island blood red.

“I feel it is healthily letting off steam but it is growing ... the base has doubled in size since 24 December when we first saw it again. And it’s getting higher,” resident Chris Egan told Fairfax media.

The volcano, which first erupted in 2009, had been rumbling in recent weeks before exploding violently in the past few days, the New Zealand Herald reported.

An Air New Zealand flight between Auckland and Nuku’alofa on Monday was diverted to Samoa and later returned to New Zealand because of the volcano, the airline said in a statement.

A return service had been scheduled to fly on Tuesday, the airline said, but had been cancelled because of volcanic activity. The volcano was not disrupting flights to other regions, it said.

Regional carrier Fiji Airlines also turned around a flight to Tonga on Monday, citing safety concerns, and domestic flights were grounded in Tonga.

No damage is reported and New Zealand’s VAAC said the ash cloud was expected to dissipate by the end of Tuesday.

Mexican volcano spews ash 29,000 ft in the air

A huge ash column exploded into the sky from one of Central America’s most dangerous volcanoes on Wednesday, reaching airplane-level heights of the atmosphere.

Mexico’s Colima volcano played host to a “strong vulcanian-type explosion” at 9:15 a.m. local time on Wednesday. The mountain belched an ash column more than 4 km above the summit, with volcanic matter rising to 29,000 ft (9 km). The resulting ash flow eventually drifted to the northeast, Volcano Discovery reported.

A webcam focused on the active stratovolcano captured the powerful blast.

A small pyroclastic flow that descended the steep slope of the volcano was generated during the explosion.

The Protección Civil (Civil Protection) said there is not a forecast of ash falling in the region, which is located in southwestern Mexico, according to Mashable. The volcano, which is also known as the ‘Volcano of Fire,’ straddles the states of Colima and Jalisco.

Australian hiker: Eruption sounded like a huge bomb
An Australian hiker has told how he and his group were forced to flee down a mountain in Guatemala after a volcano sent cloud of ash raining down upon them.

The hikers were trekking near the volcano Fuego when it violently erupted on Saturday (local time), with one saying it "sounded like a jumbo jet taking off ... with the occasional explosion that sounded like a huge bomb".

It was Fuego's largest eruption in three years.

"There was an immediate change in air quality that began to coat my exposed skin with volcanic ash," said Melbourne man Justin Gallant, who was one of about 30 tourists and guides taking the popular but gruelling seven-hour trek up the adjoining peak of Acatenango volcano.

"The ash seemed like a cloud that made me cough. I was nervous about the ash getting into my lungs.

"The guides told us that the military and volcano experts had told us to descend as it was far too dangerous to be so close and there was a risk the lava could reach camp.

"I began to get a bit nervous and was keen to descend. Several hikers began to run most of the way down the mountain."

Mr Gallant said as he descended the mountain, Fuego was making a "thunderous sound" and he could see volcanic ash exploding from the top.

The eruption sent ash falling on the capital Guatemala City and the UNESCO town of Antigua and led to the closure of the international airport for much of Sunday. People were evacuated from nearby villages.

Melbourne woman Jade Nobel was working as a volunteer at a hostel in Antigua when the volcano erupted.

"All of a sudden it went really dark and started what I thought was spitting rain, until I looked up and got a clump of ash in my eye," she said.

"We went outside the front of the hostel and within a minute or so my t-shirt was covered in ash.

"We spent hours sweeping it all up and even now, I've just been out and I'm covered in a film of ash."

Tourists flock to Antigua using it as a base to hike near to several of the world's most active volcanos that line the edge of the Caribbean and Cocos tectonic plates.

Fuego is about 16 kilometres from Antigua and has been very active in recent weeks, providing spectacular displays of daily small lava eruptions which are visible from Antigua.

Fuego's most recent large eruption was during 2012 when more than 33,000 people were evacuated from their homes.

Now safely in Antigua, Mr Gallant said he had not ruled out trekking another of Central America's active volcanos.

"I was amazed by the force of Mother Nature," he said.

"And getting down safely, I am now so grateful for the rare experience."
