Kumamoto - The Meteorological Agency on Monday raised the volcanic alert level for Mount Aso from 1 to 2, prompting local authorities in Kumamoto Prefecture to ban entry to areas within 1 km of the crater of Mount Naka, one of five peaks in the active volcano's central cone group.

The alert includes a warning for rocks ejected from Mount Naka in the off-limits areas.

The move came after the mountain belched a small amount of volcanic ash Friday and experienced a small eruption Sunday.

Red sky at night: Sicily looks on as Mount Etna erupts in spectacular fashion

After reports of mysterious mass animal deaths around the planet, photos of a fierce volcanic eruption might confirm that the end of the world is nigh.

Thankfully, these magnificent pictures of Mount Etna's latest eruption are merely a chance to revel in the awesome power of nature rather than a reason to start stocking up on canned goods.

The 3,329-metre (10,922-feet) volcano erupted for around an hour yesterday evening, lighting up the Sicilian sky and providing amazing scenery for the village of Milo, just 12 kilometres away.

Fire in the hole: Mount Etna spews lava on the southern Italian island of Sicily yesterday evening
Etna is Europe's tallest and most active volcano and has seen increased activity in recent months yet its seismic might poses no immediate threat to the nearby towns and cities.

According to the Italian Institute of Geophysics and Volcanology, a slight increase in Etna's volcanic tremors had been recorded on Tuesday, reaching its peak at 7am local time yesterday.

The activity diminished but at 9:30pm local time on Wednesday night, Etna roared into life sending lava spewing down its sides.

Expert says eruption of Etna volcano linked to earthquake in Spain

Rome - The eruption of the Etna volcano in southern Italy early Thursday is connected to the earthquakes that rocked the Spanish region of Murcia, killing 12 people and injuring more than 170 others, a seismology expert said Thursday.

"We are currently witnessing an intense seismic activity in the entire Mediterranean area from Spain all the way to Malta which has a certain impact on regional volcanoes," said Domenico Patane, director of the Sicily office of Italy s National Geophysics Institute.

Patane said volcanoes are like windows from where underground magma surfaces and it's normal that they respond to earthquakes occurring in a geographic proximity.

"The Spanish eastern coast hit by the quake, after all, lies close to Italy, in the Mediterranean. Both Spain and Sicily are on the same earth plate," he said.

The earthquakes in Spain on Wednesday, which could be felt in Madrid, reportedly had their epicenter near the towns of Lorca and Totana in the Murcia region. The initial tremor of 4.4 magnitude was followed by a quake of about 5.2 magnitude.

Tungurahua continues to erupt, Taal grows increasingly restless, explosions on Etna (and more)

The light at the end of the finals tunnel has appeared - only one set of papers (where I posed to my volcanoes class the question "if someone asked you 'why bother monitoring volcanoes?', how would you respond?") to grade now. There hasn't been a lot of new eruption news, but there has been a lot of news of simmering volcanoes and threats from volcanoes after eruption. However, we'll start with one that is actively erupting.

Tungurahua in Ecuador erupting during the first week of May, 2011.
Ecuador: Tungurahua continues with its largest eruption since 1999 (video) - and thanks to the bevy of news that Eruptions reader Kirby has sent me, there is a lot to cover. The Instituto Geofisico has put the volcano on Orange Alert status after strombolian activity produced 2-7km / 6,500-23,000 foot ash plumes and a constant sound of explosions/rumbling. The volcano is putting on an impressive show at the summit, with incandescent blocks cascading down the upper flanks of the volcano (see top left), some of which are apparently the size of cars. IG geologists have been quoted as saying the volcano is showing signs of "increased pressure", but the details are scarce. Crop and livestock damage due to the ash in the villages around Tungurahua has been extensive, and now the government will purchase new lands for refugees to move that are a safe distance from the volcano. Even with all this activity, Tungurahua did not stop people from voting in Ecuador.

Guatemalan departments of Quetzaltenango and Retalhuleu were declared this Friday in yellow alert due to the increased activity of the volcano Santiaguito.

According to the National Institute for Seismology, Vulcanology, Meteorology and Hydrology of Guatemala (Insivumeh), the increase is manifested in the number of explosions per hour.

US: Volcano Watch: Kilauea activity update

The floor of Pu`u `Ō `ō crater continues its slow rise as lava pours out of a new vent at the base of the east wall. The height of the floor has risen 20 m (66 ft) over the past two weeks.
Lava erupted continuously within Pu'u 'O'o over the past week, feeding a small lava lake in the center of the crater. Changes in eruptive output commonly resulted in overflows from the lake that slowly built up the crater floor, which is about 70 m (230 ft) below the east rim of Pu'u 'O'o. No lava is erupting outside the crater.

A small, stable lava lake was also present deep within the Halema'uma'u Overlook vent during the past week. Volcanic gas emissions remain elevated, resulting in relatively high concentrations of sulfur dioxide downwind.

Simmering Ecuadorian Volcano Spews Ash Sky High

Residents of Baños, Ecuador were doing what little they could on Saturday to clean their town of a thick coating of ash spewed by the "Throat of Fire" volcano after it erupted on Friday.

Lorry-sized boulders spew from Ecuador volcano as 300 people flee for their lives

Ecuador's Tungurahua volcano hurled lorry-sized pyroclastic boulders more than a mile in a powerful eruption that prompted at least 300 people to flee their homes, authorities said.

Schools were closed for a third straight day as ash showered down on a dozen towns in the sparsely populated area surrounding the 16,480-foot volcano.

Thundering explosions could be heard miles from Tungurahua, which is on the Andes cordillera 84 miles southeast of Ecuador's capital, Quito.

Volcano In Ecuador Erupts Friday




Banos, Ecuador -- Tungurahua Volcano spews ash as high as 10km (33,000-feet) into the air, triggering residents to evacuate and officials to divert flights. Known as "Throat of Fire," Tungurahua is one of eight active volcanos in Ecuador.

Ecuador's "Throat of Fire" volcano erupted today spewing ash that forced hundreds of residents to flee, authorities said.

Loud explosions shook the ground and rattled windows near the volcano, known as Tungurahua in the indigenous Quechua language, 81 miles southeast of Quito, officials said.

Two Russian Volcanoes Spew Ash

Kamchatka volcanoes: A cluster of snow-capped volcanoes stretching across eastern portions of Russia's Kamchatka Peninsula.
Two of Far East Russia's most active volcanoes threatened aviation and wildlife during eruptions that spewed ash above the Kamchatka Peninsula.

Ash from Shiveluch soared nearly five miles high near some key trans-Pacific aviation routes.

RIA Novosti reports an eruption of Kizimen volcano brought hazardous conditions to areas inhabited by wild animals, including some endangered species.

The news agency said reindeer were leaving their normal habitat because their usual winter food supply of moss was buried beneath a thick crust of ash-covered snow.

Experts from the Krontosky Nature Reserve told reporters that reindeer numbers may be reduced to less than 1,000 as a result of the eruption.
