Australia's only two active volcanoes have both erupted - and scientists on board a ship conducting research nearby caught the rare event on film.

The Big Ben volcano on remote Heard Island in sub-Antarctica, almost 1800 kilometres north of Australia's Antarctic base at Davis Station, erupted a combination of poisonous gases and red-hot lava. It was the first time it had done so in decades.
We witnessed the lava descending Big Ben interacting dramatically with the snow and ice cover of the mountain.

The other volcano, on the neighbouring McDonald islands, erupted gas only. Scientists on board the CSIRO's RV Investigator were visiting the islands to conduct research into the concentration of iron in Antarctic waters.

"We witnessed the lava descending Big Ben as it interacted dramatically with the snow and ice cover of the mountain," said ANU volcanologist Professor Richard Arculus, who witnessed the eruption first hand.

A pillar of ash shot 10,000 feet into the sky in a violent explosion of the Colima volcano in south-central Mexico. The event was captured on a web camera installed by scientists to monitor the active volcano in the Jalisco province.

The awe-inspiring timelapse footage shows the volcano as it burst last Friday. The mountain is still erupting intermittent explosions varying from 3,000ft to 9,800ft in height, according to VolcanoDiscovery.

Karymsky volcano in Russia's Kamchatka region spews ash 3km high - hours after major earthquake

A HUGE volcano has seen a massive eruption of toxic ash and gas just hours after a major earthquake rocked the region, causing shopping centre evacuations.


The Karymsky volcano in Russian Kamchatka's eastern volcanic zone spewed ash up to 3km into the air, according to the Regional Emergencies Ministry.

Airlines have been placed on an "orange" warning to avoid the area following today's eruption.

It came less than 48 hours hours after a magnitude 7.3 earthquake tore through the region, followed by a series of at least seven less powerful aftershocks.

Terrified shoppers fled from a shopping mall after feeling the tremors inside.

The epicentre of the earthquake was within about 20 miles of the 1,486 metre-high magma mountain, prompting fears seismic activity is on the rise and there could be a catastrophic earthquake, volcanic eruption or both.

The quake struck an area close to the Ring of Fire, an arc of fault lines circling the Pacific Ocean.

It suffers many earthquakes and volcanic eruptions, but the National and Pacific Tsunami Warning Centers have said there is no current risk of a tsunami from the powerful quake.

The area has seen much volcanic activity this month.

Scientists film rare eruption of remote Antarctic volcano

Australian scientists have witnessed the rare eruption of an Antarctic volcano off the coast of the frozen continent.

The scientists, from Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), filmed the volcanic event by chance while aboard research vessel "Investigator" studying the fringe of Antarctica's Heard Island.

The crew, working in conjunction with the University of Tasmania's Institute for Marine and Antarctic Studies (IMAS), were actually looking to study underwater volcanoes before the land-based variety caught their attention.

Heard Island, a remote sub-Antarctic region, is home to Big Ben, an active volcano which is believed to have only erupted three times since the turn of the century.

Given the island's isolation, viewing Big Ben - which is mostly covered in ice throughout the year - during an eruption is considered a geoscientific rarity. Often, satellite images provide the only evidence that an eruption has occurred.

One of Azerbaijan's largest volcanoes erupts

Akhtarma-Pashali volcano erupts
One of the largest volcanoes of Azerbaijan Akhtarma Pashali awoke in the country's Hajigabul region on the night of January 25.

The first eruption occurred at 07:20, when the fire rose to 120-150 meters in the air. The second was fixed 10 minutes later, when the fire rose to a height of 20 meters. The total area of the lava spill was 200-250 square meters.

The mud volcano has ceased erupting, according to the Chairman of the regional emergency commission Sahib Aslanov. No victims were reported, as no settlements are located around the area.

Akhtarma Pashali is located in 35 kilometers of the city of Shirvan. The diameter of the crater is approximately 10 square kilometers.

Aslanov emphasized the last eruption of this mud volcano occurred in 1963, while the first eruption of the volcano was reported in 1948.

Mud volcanoes are a fairly widespread geological phenomenon and over a thousand mud volcanoes are known to exist in the world.

The dissemination of mud volcanoes usually indicates the existence of large oil and gas basins, therefore oil and gas-rich Azerbaijan ranks first in the number of mud volcanoes in the world. The territory of Azerbaijan places 344 mud volcanoes and 133 of them are located in the country's Caspian Sea section.

Peru's El Misti volcano awakens

The last eruption of great magnitude at Misti was 2,000 years ago, informs Peru's volcano authority.

The iconic symbol of Arequipa, the Misti volcano, that gazes over the southern Peruvian city has long been considered 'asleep.'

However, studies by the Southern Volcano Observatory (OVS, Spanish acronym), reveal that it is awake and emitting gases, informs Publimetro.

It is currently considered the greatest risk in the South American country, as thousands of habitants reside near its crater.

"The gases that Misti emits are magmatic. This confirms that the volcano is active and is not sleeping, as many people think," VS engineer, Luisa Macedo, told AFP over the phone from Arequipa, according to Publimetro.

The volcano is located only 17 kilometers from the city.

The engineer informed that four weeks ago a group of researchers from OVS took images of the Misti crater. With their investigation were able to identify magmatic activity.

"The gases reach 500 meters and contain sulfuric acid, carbon and calcium," said Macedo. He informed that the distance prevents the nearby communities being affected by the emissions.

Another OVS specialist, Domingo Ramos, explained that although the volcano is active, it does not necessarily mean there is danger of a hazardous eruption.

More than 1,200 people have been evacuated from their homes as a volcano in eastern Indonesia spews clouds of ash and toxic gas into the air.

Officials said they had distributed thousands of gas masks to villagers around Mount Egon in eastern Flores island as the choking fumes from the volcano intensified.

All residents within three kilometres of the volcano were ordered to evacuate and roads were also closed.

Authorities said they were prepared to issue a wide-scale evacuation order if the situation deteriorated further.

"We are on a high alert and ready to evacuate any time," disaster mitigation official Silvanus Tobi said.

The volcano began rumbling last month but has become more active in recent days.

An "orange" code of warning for the aviation has been issued, and travel companies have been asked not to organize tours to the areas close to the Zhupanovsky volcano


The Zhupanovsky volcano in Russia's Far Eastern Kamchatka Peninsula on Tuesday released ash to the height of 8 kilometers above the sea level after almost two months of relative calm, a member of the local group of the Institute of Volcanology and Seismology has said. "Today at around 4.30 p.m. local time [3.30 a.m. GMT] the Zhupanovsky volcano spewed ash to the height of up to 8 kilometers [5 miles] above the sea level.

The ash column could be seen with the naked eye from Petropavlovsk-Kamchatsky and some other settlements," the scientist said. Experts said the ash cloud spreads in the eastern direction towards the Pacific Ocean. The populated areas are currently not under threat. "At the moment, the ash cloud has spread to 20 kilometers and it continues moving towards the ocean," the member of the group said. An "orange" code of warning for the aviation has been issued.

Peru's Ubinas volcano erupts: 3km smoke ash cloud

Peru's Ubinas volcano
Peru's Ubinas volcano
Peru's Ubinas volcano erupted on 15 January at 12.53pm local time (7.53am GMT), emitting smoke and ash that affected seven nearby towns. The volcano spewed an ash cloud some 9,842ft (3km) high, according to the scientists who monitor the volcano.

Volcanologists from the Volcanology Southern Observatory said the ash spread south and southeast some six miles (9.65km), affecting seven surrounding towns. Scientists expect smaller eruptions of smoke and ash to continue throughout the day.

Just days earlier, a team of volcanologists had ascended Ubinas to study the crater and take readings. After being dormant for several years, the volcano has become increasingly active since September 2013. The Ubinas volcano is in Peru's Moquegua department, 776 miles south of Lima.
