The Shiveluch volcano in the Russian Far East erupted on Tuesday morning local time, throwing a plume of ash up to 20km into the atmosphere. The Kamchatka authorities are monitoring the lava flow, while regional residents were told to stay inside and wear masks.

The eruption began around 1am and reached its maximum five hours later, according to local volcanologists. Plumes of hot ash rose into the sky, followed by rockfalls and lava flow from the mountain, which rises 2,500 meters above the Pacific Ocean.

12 eruptions in 24 hours at Popocatepetl Volcano in Mexico

mmmmmm
There have been 12 eruptions in the last 24 hours at Popocatepetl Volcano in Mexico. Ash fell in the city of Atlixco, close to the volcano. Authorities warned to stay away from the volcano's crater.

Explosions continue at Popocatepetl Volcano in Mexico. In the statement made by the Mexican National Center for Disaster Prevention (CENAPRED), it was stated that 12 new eruptions took place in Popocatepetl Volcano in the last 24 hours, and 199 gas and ash outputs were recorded.

It was reported that the ash from the mouth of the volcano spread to the east and southeast directions with the effect of the wind, and it was stated that ash precipitation occurred in the city of Atlixco, which is located just southeast of the volcano.

Huge ash cloud as Russia's Shiveluch volcano erupts

mmmmmmm
One of Russia's most active volcanoes has erupted, with a vast cloud of ash rising into the sky and smothering villages.

The eruption triggered an aviation warning around the county's far-eastern Kamchatka peninsula.

Shiveluch volcano erupted just after midnight local time, reaching a crescendo about six hours later.

Villages have been carpeted in grey ash as deep as 8.5cm amid warnings of mud slides.

Medieval writings on lunar eclipses may help date volcanic eruptions

When medieval monks were looking up at the night sky, writing down their observations of celestial objects, they had no idea that their words would be invaluable centuries later to a group of scientists in a completely different field: volcanology.

A new study published Wednesday in the peer-reviewed journal Nature explains how descriptions of lunar eclipses by monks and scribes were key in studying some of the largest volcanic eruptions on Earth.

Using a combination of these medieval writings and climate data stretching back centuries, researchers were able to clarify the date of around 10 volcanic eruptions that took place between the year 1100 and 1300.

"I was listening to Pink Floyd's Dark Side of the Moon album when I realized that the darkest lunar eclipses all occurred within a year or so of major volcanic eruptions," lead author Sébastien Guillet, senior research associate at the Institute for environmental sciences at the UNIGE, said in a press release. "Since we know the exact days of the eclipses, it opened the possibility of using the sightings to narrow down when the eruptions must have happened."

Researchers say that getting a more accurate date for these Earth-shattering events could help paint a clearer picture of how volcanos contribute to extreme climate variability.

Semeru volcano (East Java, Indonesia): actively growing lava dome generates pyroclastic flows

Pyroclastic density current from Semeru
© INFO SEMERUPyroclastic density current from Semeru volcano yesterday.
The actively growing lava dome in the inner Jonggring Saloko summit crater generated a block-and-ash flow yesterday.

The pyroclastic flow descended along the steep southeastern ravine and reached approx. 1,5 km length as can be seen in the video recorded by local observers in Huntap. Grey ash plumes formed as they separated from the current (so-called phoenix clouds).

The reason for this flow was presumably either accumulated lava material from the front of the lava flow or destabilization of the lava dome resulting in the partial collapse.

Airlines warned of danger from erupting Bezymianny volcano in Russia

mmmmm
Bezymianny in Kamchatka ejected a 12,000-meter-tall ash cloud, Russia's air regulator said

Aircraft have been strongly advised to review their flight routes due to a powerful volcanic outburst in Russia's far-eastern peninsula of Kamchatka, according to a statement by the Federal Agency for Air Transport, Rosaviatsiya, published on Saturday.

Rosaviatsiya said that on Friday morning Bezymianny volcano, which is located in the eastern part of the peninsula and is considered to be one of the most active in the region, erupted with a 12,000-meter column of ash, which then started to drift off to the southeast.

Indonesia's Anak Krakatoa volcano erupts, belches huge ash tower

nnnnnnnn
The offspring of Indonesia's infamous Krakatoa volcano erupted several times on Tuesday, sending a huge volcanic ash tower some 2,500 meters (8,200 feet) into the sky.

Mount Anak Krakatoa, which means Child of Krakatoa, erupted four times, officials said, with the biggest followed by another that sent a column of smoke and ash 1,500 meters above its crater.

"This is part of an eruption phase associated with the formation of a new body for the volcano," Oktory Prambada, an official at the Center of Volcanology and Geological Hazard Mitigation, told AFP.

In 2018, its crater partly collapsed when a major eruption sent huge chunks of the volcano sliding into the ocean, triggering a tsunami that killed more than 400 people and injured thousands.

There were no immediate reports of injuries or damage on Tuesday.

Indonesia's Merapi volcano erupts, spews hot lava

MMMMM
Indonesia's Mount Merapi, one of the world's most active volcanoes, erupted late Friday and continued to spew hot ash and other volcanic material on Saturday.

Footage of flaming lava pouring out of the crater and a tall column of hot cloud rising 1,300 metres into the air was taken by the government-run Merapi Volcano Observatory on Friday night.

The volcano continued to spew hot ash and hot lava was visible on Saturday.

"Residents should anticipate the disruption due to the volcanic ash from Mount Merapi eruption and please be on alert for the danger of volcanic mudflow, especially when it rains around Merapi," the country's volcanology agency said in a statement Saturday.

Karangetang volcano (Api Siau Island, northern Indonesia): incandescent avalanches separate from lava dome

The effusive eruption of the volcano remains intense.

We are regularly given first-hand information from our local expedition leader and volcanologist, Andi, about the volcano's behavior. Glowing lava blocks continue to detach from the actively growing lava dome, located within the Crater 1, and roll over the western and eastern slopes, most of which reach the base of the dome area. Feel free to enjoy a noteworthy video from the ongoing activity here.

Some people have been evacuated to avoid being affected by large hot rock falls that may result in dangerous pyroclastic flows.

Indonesia's Merapi volcano erupts, covers villages in ash

Indonesia's Mount Merapi, one of the world's most active volcanoes, erupted on Saturday (Mar 11), spewing out smoke and ash that blanketed villages near the crater.

There were no immediate reports of casualties, the country's disaster mitigation agency said.

Images broadcast on local outlet Kompas TV showed ash-covered houses and roads at a village near the volcano, located on Java Island, near Indonesia's cultural capital Yogyakarta.

The Merapi Volcano Observatory estimated the ash cloud reached 3,000m (9,600 feet) above the summit.
