Fuego volcano spews ash onto nearby towns in Guatemala


Guatemala’s Fuego volcano erupts with fiery lava.
A restive volcano near Guatemala's capital spewed ash on nearby towns Wednesday, including on a colonial-era city popular with tourists, officials said.

The overnight eruption of Fuego Volcano - whose name means "fire" in Spanish -sent ash billowing up to five kilometers (three miles) into the sky and rivers of lava up to two kilometers long, according to Guatemala's Volcanology Institute.

Light tremors were also felt up to 25 kilometers away.

Strong gusts of wind could carry the clouds of "fine ash particles" to Guatemala City, 45 kilometers distant, said David de Leon, a spokesman for the government's disaster coordination service.

El Misti volcano waking up from nearly 600-year slumber in Peru

Peru's typically snow-capped El Misti volcano, also known as Putina, is showing signs of awakening from a period of relative slumber that goes back to the 15th century.

While gas emissions have occurred since eruptions around 1440 and 1470, the volcano is now showing signs of rising magma.

El Misti is considered the most dangerous volcano in Peru, with about 1 million people around Arequipa under threat.

Santiaguito volcano in Guatemala
A new explosion at Santiaguito volcano, Guatemala was recorded on February 7, 2016.

Look at the pictures of the large ash and gas clouds engulfing the sky. Powerful.

Turrialba volcano blows ash and noxious gases 500 meters into the air in Costa Rica

Turrialba Volcano
On Saturday afternoon, geologists at the Observatory on Volcanology and Seismology at the National University of Costa Rica (Spanish acronym: OVSICORI) reported a new eruption at the Turrialba Volcano, the most active colossus in their country.

The volcanic event took place about ten minutes before 2:00 pm during a warm, yet extremely windy, afternoon.

The seismographic sensors of the OVSICORI began stirring after 1:50 pm, at which time the scientists on duty activated their crater cameras to capture the eruption.

In the beginning, the eruption was mostly a slow emanation of volcanic ash and noxious gases.
About ten minutes into the natural event, a more powerful ejection occurred and a solid plume formed about 500 meters into the air.

Thanks to the crisp weather conditions and the clear-blue afternoon skies, the eruption on the western crater was visible from the summit of the nearby Irazu volcano.

Chemistry experts at the OVSICORI combined their observations with data from the Institute of Meteorology to provide a forecast of where the ash clouds were headed yesterday.

Indonesia's Mount Soputan volcano erupts


Mount Soputan has erupted 39 times in the last 600 years
Mount Soputan volcano in North Sulawesi province of Indonesia erupted several times on Sunday, spewing a column of hot ash by up to 2.5 km high, official of disaster management agency said.

Mount Soputan, located some 60 km from Manado, capital of the province, has high potential for further big eruption which is indicated by persistent tremors with amplitude of 41 mm, Spokesman of National Disaster Management Agency Sutopo Purwo Nugroho disclosed.

Several subdistricts in Minahasa Tenggara district were hit by rains of ash and volcanic materials that the local disaster agency distributes masks to protect local residents from the impact, he told Xinhua via phone.

The authorities have banned villagers or visitors from entering the area of 4 km from the crater, but at the southwest of the crater the evacuation zone is at 6. 5 km, Mr. Sutopo said.

The 1,874- meter high Mount Soputan is one of Indonesia's active volcanoes whose number is about 129, according to the National Volcanology Agency.

Steam / ash plume and thermal hot spot at Barren Island on 1 Feb 2016
Minor eruptive activity (possibly strombolian) seems to continue on the remote island, at least intermittently.

Yesterday and the day before, a weak steam and possibly ash plume was visible on satellite imagery as well as a thermal hot spot.

Australian volcanic eruption captured on film

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.

Timelapse video captures spectacular explosion of Mexico's Colima volcano

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

The volcano erupted within 48 hours of the 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

Big Ben has erupted at least three other times in the past 15 years
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.
