Chief of Geological Disaster Mitigation and Volcanology Agency, Surono, said Dieng Mountain in Central Java has seen increasing activities in the past few days as poisonous gas starts spewing into the air.

The Indonesian Red Cross has evacuated inhabitants living in four villages of Sumberejo, Serang, Kaliputih and Simbung. This causes tourists to avoid coming to the area.

A staff at a homestay in Dieng said, "Some cancellations are indeed made. Tourists called off visits after being informed of the volcanic activities," said Dwiyono who, like many Indonesians, uses one name.

He believed tourist attractions in Dieng are still secure since the Timbang Crater, which produces carbon dioxide, is located 12 kilometers away from the said spots.

Activity Increases At Costa Rica's Poas Volcano

Activity at the Volcano Poas is increasing rapidly, while at the same time drying up the lagoon, say experts, a team of geologists and volcanologists from the seismological network of the Universidad de Costa Rica (UCR)

The team visited the colossus on Wednesday where the recorded 18 "phreatic eruptions" in a three hour period, when normal is 1 or 2 per day.

The temperature of the crater is also increasing, which is causing the lagoon to dry up and possibly disappear.

Experts warn that this could bring more acid rain and ash in the area around the volcano.

However, the activity of Poas is not a danger to tourists and the national park will continue open.

A phreatic eruption, also called a phreatic explosion or ultravulcanian eruption, occurs when rising magma makes contact with ground or surface water.

The extreme temperature of the magma (anywhere from 600 to 1,170 °C (1,112 to 2,138 °F)) causes near-instantaneous evaporation to steam resulting in an explosion of steam, water, ash, rock, and volcanic bombs.

Five Years On, Indonesia's Mud Volcano Still Erupting

Porong - "Lusi" the mud volcano is slowing down five years after it engulfed fields, homes and factories in a heavily populated part of Indonesia, but experts say the danger may last for decades.

Almost every minute another jet of thick, boiling, foul liquid shoots into the sky followed by a white cloud of vapour, adding to the vast lake of mud which now covers more than 700 hectares (1,730 acres) of Java island's Sidoarjo district.

"My whole life is buried here. I've lost everything: my house and the warung (streetside food stall) I opened just before the disaster," said Harwati, a 35-year-old widow and mother-of-two who now guides tourists around the disaster zone.

"Since then, life has been really hard. It's difficult to find a job."

She is one of some 40,000 people who have been forced out of their homes by the inexorable ooze, which appeared without warning on May 29, 2006 in the middle of a rice field.

Gradually, the mud has swallowed 12 villages, 30 factories, dozens of shops and a busy highway near the country's second largest city of Surabaya. Twelve people have been killed, but many more lives have been wrecked.

As the mud continues to flow, a row over its cause also festers with some experts and victims accusing a local gas drilling company of sparking the torrent - an allegation it denies.

Iceland: Volcano grounds 500 flights but plume shrinking

Reykjavik - Activity at Iceland's erupting volcano has slowed significantly and its ash plume, which has dropped to a fraction of its 20 kilometre peak, could disappear by the weekend, experts said on Tuesday.

The plume of ash from Grimsvotn, located in the southeast of Iceland at the heart of its largest glacier, Vatnajoekull, had fallen to two kilometers on Tuesday evening, according to an Icelandic crisis management official.

The column "is decreasing now and the height of the plume is around two kilometers so it's dramatically decreased," Thorir Hrafnsson, a spokesman for Iceland's crisis management agency, told AFP.

"If it behaves like earlier eruptions, hopefully it will be over by the weekend," he said, while stressing "it's very hard to guess."

At an altitude of just two kilometres, the plume "will not be dangerous for air traffic," Hrafnsson said, acknowledging that ash still in the air from the initial blast could continue to cause problems.

US: Volcano, Power Failure Vex Weekend Air Travelers

Just one year after a volcanic eruption decimated the air travel network across Europe for nearly a month, another volcano in Iceland has decided to erupt. Will this new eruption bring European air travel to its knees again? The Los Angeles Times reports that Iceland's airports were closed Sunday and trans-Atlantic flights were being diverted around that country's airspace. Last year it was the Eyjafjallajokull volcano and now it is a volcano with another unpronounceable name, the Grimsvotn volcano, which is spewing ashes into the atmosphere. At this time the air travel disruption is only impacting flights over Iceland, but the disruption could expand at any time.

Here we go again: Icelandic volcano ash could enter UK airspace, forecasters warn

Ash from an erupting Icelandic volcano that has already grounded planes locally could enter UK airspace by Tuesday, forecasters have warned.

The Grimsvotn volcano began erupting on Sunday, causing flights to be cancelled at Iceland's main Keflavik airport after it sent a plume of ash smoke and steam 12 miles into the air.

However experts said the eruption was unlikely to have the dramatic impact that the Eyjafjallajökull volcano had in April last year, when flights were cancelled over the UK and much of Europe for several days.

Paul Mott, forecaster at Meteogroup, said ash from the volcano could potentially reach the UK by Tuesday.

Comment: This eruption may well merit caution, but remember that we've been here before and been bamboozled before:

12-Mile-High Ash Plume Shutters Iceland Airports

More than a year after an Icelandic volcano wreaked havoc for millions of air travelers across the globe, a new eruption has spewed an ash plume 12 miles in the air. Iceland's airports have been shut down, and ash could affect Europe later this week.

Ash could reach northern Scotland by Tuesday and parts of Britain, France and Spain by Thursday or Friday if the eruption continues at the same intensity, airlines were warned on Sunday.

The warning is based on the latest 5-day weather forecasts, but is being treated cautiously because of uncertainties over the way the volcano will behave and interact with the weather.

The Grimsvotn (GREEMSH-votn) volcano, which lies beneath the ice of the uninhabited Vatnajokull glacier in southeast Iceland, began erupting Saturday for the first time since 2004, sending ash, smoke and steam 12 miles into the air.

It was the volcano's largest eruption in 100 years.

Largest Volcanic Eruption in Grímsvötn in 100 Years

The current volcanic eruption in Grímsvötn on Vatnajökull glacier is the largest in that volcano 100 years and larger than the one in Eyjafjallajökull last year. It is similar to the eruption of 1873, according to geophysicist Magnús Tumi Gudmundsson. A large flood is not expected.

This morning the ash cloud was 15 to 18 kilometers high which means that the volcanic eruption is ten times more powerful than the last eruption in Grímsvötn in 2004, Gudmundsson told ruv.is.

However, it is not unique. Grímsvötn goes through phases where it erupts often in a period of 60-80 years, then there are quieter periods of equal length.

Iceland's Grimsvotn volcano erupting

Reykjavik, Iceland - Iceland's most active volcano has started erupting, scientists said Saturday - just over a year after another eruption on the North Atlantic island shut down European air traffic for days.

Iceland's Meteorological Office confirmed that an eruption had begun at the Grimsvotn volcano, accompanied by a series of small earthquakes. Smoke could be seen rising from the volcano, which lies under the uninhabited Vatnajokull glacier in southeast Iceland.

One eyewitness, Bolli Valgardsson, said the plume rose quickly several thousand feet into the air.

Grimsvotn last erupted in 2004. Scientists have been expecting a new eruption and have said previously that this volcano's eruption will likely be small and should not lead to the air travel chaos caused in April 2010 by ash from the Eyjafjallajokul volcano.

Reykjavik, Iceland - Iceland's most active volcano erupted Saturday, with a white plume shooting 18,000 feet into the air, scientists said.

The eruption was followed by around 50 small earthquakes, the largest of which measured 3.7 on the Richter Scale, according to Iceland's meteorological office.

There was a similar eruption at the same volcano in 2004.

Scientists don't believe this eruption will lead to air travel chaos like that caused by ash from the Eyjafjallajokul volcano in April 2010.

The Grimsvotn volcano is located underneath the Vatnajokull glacier in southeast Iceland.

Sparsely populated Iceland is one of the world's most volcanically active countries and eruptions are frequent.

They often cause local flooding from melting glacier ice, but rarely cause deaths.

Last year's Eyjafjallajokul eruption left millions of air travelers stranded after winds pushed the ash cloud toward some of the world's busiest airspace and led most northern European countries to ground all planes for five days.

In November, melted glacial ice began pouring from, signaling a possible eruption. That was a false alarm but scientists have been monitoring the volcano closely ever since.
