A state of emergency has been declared for Vanuatu's Ambae Island as a volcano continues to spill thick heavy ash.

Thousands of residents who call the island home have been warned they may need to evacuate after up to 1cm of ash has fallen in some areas north of the island on Tuesday night.

The situation was described as 'becoming critical in some areas' and national EMT coordinator Dr Basil Leodoro told Vanuatu Daily Post they had 'received reports of houses collapsing due to the weight of the ash.'

Popocatepetl volcano in Mexico erupts and sends huge plume of smoke and flaming debris into the sky

The smoke begins to turn a dark red colour as it continues spewing out of the volcano
This is the incredible moment a volcano explodes into life sending a huge cloud of smoke into the sky and flaming debris flying.

The Popocatepetl volcano, located between the central Mexican states of Morelos, Puebla and Mexico, burst into life.

In the video, a huge plume of black smoke can be seen coming out from the volcano's crater.

Is the Pacific Ring of Fire becoming more active?

Indonesian schoolchildren walk together at Sipandak elementary school in Tiga Pancur village in Karo, North Sumatra on Feb. 19, 2018, as thick volcanic ash from Mount Sinabung volcano rises into the air following another eruption. Sinabung roared back to life in 2010 for the first time in 400 years and has remained highly active since.
Recent eruptions prompt calls for better building standards and evacuation plans in Southeast Asia

When Bali's Mount Agung started rumbling last September, authorities on the Indonesian resort island -- mindful of the destruction the 3,000-meter volcano had caused in 1963 -- began warning residents to evacuate. Tremors of varying intensity continued until Nov. 21, when it finally began to erupt, forcing as many as 140,000 people to seek refuge. More than four months later, it still hasn't stopped.

On Jan. 23, Mount Kusatsu-Shirane, about 150km northwest of Tokyo, astounded the Japan Meteorological Agency when it suddenly erupted 2km from one of 50 areas around the country kept under constant video surveillance. Falling debris killed a member of the Ground Self-Defense Force who was skiing nearby and injured five others.

At much the same time, Mount Mayon in the Philippines began spewing ash and lava, displacing more than 56,000 people.

Then, in mid-February, Mount Sinabung in Sumatra, Indonesia, blew spectacularly, sending billowing pillars of steam and superheated ash over 7km into the air. People fled, and schoolchildren ran home wailing.

Sinabung's eruption was followed in late February by a magnitude-7.5 earthquake in Papua New Guinea, its worst in a century. Earlier in the month, a magnitude-6.4 quake rocked Taiwan's Hualien County, tilting buildings and killing 17.

Mount Sinabung erupted on April 6, 2018, spewing a massive volcanic ash column up to 5km into the air and sending hot clouds as far as 3.5km in different directions.
Indonesia's Mount Sinabung in North Sumatra, erupted on Friday (April 6) spewing a massive volcanic ash column up to 5km into the air and sending hot clouds as far as 3.5km in different directions.

The eruption took place at 4:07 pm (5:07 pm Singapore time), shocking local residents living around the volcano. Mt Sinabung had been relatively quiet for the past month.

"There was no eruption recorded in the past month. This quiet condition has been disrupted following the big eruption today," Pelin Depari, resident of Gurukinayan village said.

Volcanic lightning at Shinmoedake is seen from Kirishima, Kagoshima Prefecture, on Thursday morning in Japan.
An explosive eruption occurred early Thursday morning at Shinmoedake, a volcano in the Kirishima mountain range straddling Miyazaki and Kagoshima prefectures, the Japan Meteorological Agency said the same day.

Volcanic smoke from the 1,421-meter Shinmoedake reached as high as 5,000 meters above the crater, the highest since a series of eruptions began on March 1. Minor pyroclastic flows poured in the direction of Takaharu, Miyazaki Prefecture, which is located southeast of the crater, some spreading about 800 meters from the crater.

This was the first time since March 25 that both an explosive eruption and pyroclastic flows were observed. The two prefectural governments said they had not received any reports of injuries or damage to buildings caused by the eruption. The agency said there is no need for immediate evacuation.

Piton de la Fournaise volcano on Reunion Island has erupted
The Piton de la Fournaise volcano on Reunion Island, one of the most active in the world, began erupting this morning for the first time since July 2017.

One scientist warned of a "seismic crisis" after the eruption caused a crack in the crater stretching one mile across the French island, which is located in the Indian Ocean

The eruption was so strong its effected could be seen by satellite, which experts warning it is continuing to "intensity".

And the eruption also caused landslides and fumaroles - openings through which toxic gas escapes.

The Institut de Physique du Globe de Paris (IPGP), a French governmental research institution, said: "The volcanic tremor continues to intensify."

And IPGP seismologist Lucile Bruhat said on Twitter: "Volcanic eruption in progress in Reunion Island at Piton de la Fournaise. Seismic crisis this morning leading to dike (~1km long) opening."

IPGP flew a helicopter over the volcano and said they're local OVPF team had seen "lava fountains" erupting through the crust of the crater.

They said: "Following a reconnaissance made by a team of the OVPF at the ramparts of the Enclos, the eruptive activity could be confirmed.

Huge steam vortices filmed above Hawaii's Kilauea volcano

Hawaii volcano vortices 2013 Kilauea

The Volcanic vortices pictured back in 2013.”
Several land spouts of twisting lava were seen just above the Pulama pali at sunrise on Thursday, helicopter footage shows.

Mick Kalber, a videographer who was aboard a Paradise Helicopters flights, said: "[A] pink rainbow, amazing land spouts and a veritable plethora of lava flows made for a spectacular lava overflight this morning.

"We have often seen water spouts at the ocean entry, but this morning, due to a head downpour on the 61G flow and the right wind and heat conditions, several vortices [land spouts] appeared just above the Pali."

Comment: While this phenomenon has been recorded before, it's notable that all over the world the appearance of wind vortex formations in the unlikeliest of places appear to be increasing - and that perhaps our understanding of how they form needs to be questioned:

Turrialba Volcano
The activity at the Turrialba Volcano in Costa Rica just doesn't stop, on April 1st, two significant eruptions took place early in the morning and carried on for close to 30 minutes.

The biggest eruption was registered at 8:38 a.m. local time and the cameras located near the crater registered a column of ash that reached between 500-700 meters above the active crater. The activity at the volcano started at 6:30 a.m. with ash columns of close to 300 meters above the crater.

Seismic activity continues and a low amplitude tremor.

Several communities in the Central Valley reported ash fall, among them, Hatillo, Curridabat, Coronado, Guadalupe, Moravia, Tibas and Heredia.

The "Ayrantokan mud volcano in Baku's Garadagh district erupted on March 29 at around21:10.

The eruption lasted up to seven minutes and was accompanied by flames, which reached a height of about 100-150 meters above the volcanic crater.

The eruption covers an area of up to 2 hectares and varies from 0.3 to 1.2 meters in thickness.

There are no settlements around the mud volcano. Radial cracks have formed in the volcanic area.

Study warns Mt. Etna sliding into Mediterranean and could trigger landslides and tsunamis

Mount Etna is slowly sliding into the Mediterranean Sea, according to the first study which confirms the entire active volcano is shifting and could trigger catastrophic landslides and devastating tsunamis.

Scientists have confirmed for the first time that the entire volcano is moving in an east-south-east direction towards the town of Giarre, at an average rate of 14mm (.55 inches) a year. That's according to the study published in the Bulletin of Volcanology.

"This is the first time it's been observed in an active volcano," the study's lead author, John Murray, of the Open University told RT. "While it has been known to happen in extinct volcanoes, this is the first time it's been demonstrated for the whole volcano to be moving like this."

Researchers were able to determine the whole volcano is on the move by using a series of more than 100 GPS stations located around Mount Etna, which they monitored for 12 years.
