Bali’s Mt Agung Volcano Continues Heating Up

Posted by feww on September 29, 2017

Mass Evacuation: 140,000 people flee Bali town of Amed turning it into a ghost town

Mt Agung Volcano continues to exhale a large column of steam, smoke and ash, while ominously eying the town of Amed.

The normally bustling tourist town, located about 4km outside Mt Agung volcano’s exclusion zone, has been experiencing  more than 1,000 tremors per day, prompting residents and tourists to abandon the town.

More than 100,000 others are expected to abandon nearby villages as fears of an “imminent eruption” mount.

Authorities has set up about 500 temporary shelters outside the exclusion zone around the volcano, said the National Disaster Management Agency.

However, the shelters may prove unsafe, if a large, explosive eruption occurs.

Vanuatu Volcano: State of Emergency Declared

Meanwhile, most of 11,000 residents in Vanuatu’s Ambae island have abandoned the volcanic island under evacuation orders, as the Manaro Voui volcano continues emitting ash, smoke and volcanic gases, stoking fears of an imminent eruption.

IAEA ineffective, or corrupt to the core?

Posted by feww on January 11, 2016

Sent by a reader… edited by FEWW-JMC

“Atoms for Peace”

The International Atomic Energy Agency (IAEA) was set up in 1957 supposedly to promote the peaceful use of nuclear energy, and to prevent its use for military purpose, including nuclear weapons. It’s based in Vienna, and has “Regional Safeguards Offices,” one in Toronto and the other in Tokyo. The IAEA also has liaison offices both in New York City,  and in Geneva. Additionally, it has three laboratories in Vienna, Seibersdorf, and Monaco.

Despite being established independently of the United Nations through a separate international treaty, the IAEA Statute, the “Atoms for Peace” reports to both the United Nations General Assembly and Security Council.

The organization describes itself as follows:

The IAEA is widely known as the world’s “Atoms for Peace” organization within the United Nations family. Set up in 1957 as the world’s center for cooperation in the nuclear field, the Agency works with its Member States and multiple partners worldwide to promote the safe, secure and peaceful use of nuclear technologies.

How Safe are the Nuclear Power Plants in Japan?

Japan sits near major tectonic plate boundaries, in a volcanic zone situated on the Pacific Ring of Fire. It has had a long history of seismic activity, with powerful, destructive earthquakes that often result in tsunamis.

If there were a 101 on where not to build your nuclear power plants, Japan would fill all criteria as the experts’ top choice for the most dangerous example.

Yet the crowded country of 130 million has 54 nuclear reactors.

On 11 March 2011, Japan experienced the strongest and most destructive earthquake in its history, followed by a deadly tsunami. The magnitude 9.0 Tōhoku earthquake generated a tsunami about 14 meters high. The quake and tsunami, followed by hundreds of aftershocks, including some measuring 7.0Mw or larger, killed thousands of people, razing entire towns and villages, destroying or damaging more than 120,000 buildings. The giant tsunami also crippled the Fukushima Dai-ichi I nuclear power plant, resulting in a nuclear disaster with multiple core meltdowns and large scale radioactive fallout.

  • If the IAEA was effective, it would have shut down all nuclear power plants in Japan, long before the Fukushima meltdowns, to prevent such disasters.

  • If the IAEA was NOT corrupt, it would have permanently shut down all nuclear power plants in Japan after Fukushima meltdowns, to prevent repeat disasters.

Meanwhile, back in Japan…

IAEA Begins Evaluating Japan’s Alleged Efforts on making Nuclear Power Plants Safe (!)

On Monday, IAEA began evaluating Japanese government’s alleged improvement work on ensuring “safety” of nuclear power plants, according to a report.

“A group of experts of the International Atomic Energy Agency (IAEA) began on Monday its planned assessment of the Japanese government’s efforts to ensure safe use of nuclear power plants.”

“This mission will assess the new regulatory framework established in Japan after the Fukushima Daiichi [disaster,]” Philippe Jamet, the IAEA delegation’s head, told reporters.

“The IAEA mission to Japan includes representatives from 24 countries, according to the organization’s website. They are expected to visit nuclear facilities to inspect the infrastructure, to meet with representatives of the Japanese nuclear power industry. The mission will end on January 22. Based on the results, the IAEA will produce a report on the country’s nuclear safety,” the report said.

WE WILL SEE!

Calbuco Volcano Erupts Again

Posted by feww on May 1, 2015

Chile’s Calbuco erupts for the third time in 8 days

The Chilean volcano, located  about 1,000km  south of the capital Santiago, erupted for the third time in eight days on Thursday, sending yet another column of  volcanic matter up to 4km into the air.

The 2,015-meter high Calbuco, an extremely explosive andesite volcano, ejected about 200 million tons of ash into the atmosphere last week, blanketing multiple towns and communities, damaging the nearby salmon farms and forcing flight cancellation as far as the Argentine capital Buenos Aires, about 1,400 km away.

However, Thursday’s eruption was notably less powerful than the previous two explosions, which prompted the evacuation of thousands of nearby villagers.

The red alert  and a 20-km exclusion zone remains in effect, said Chile’s ONEMI emergency office, as officials evacuated an additional 1,580 people.

The total number of evacuees in the Los Lagos region now stands at 6.685  people.

ONEMI has posted the following update (Spanish) on its website:

Calbuco Volcano Finally Erupts

Posted by feww on April 23, 2015

Thousands evacuated as Calbuco volcano explodes

Located in southern Chile, about 1,000km  south of the capital, Santiago, the extremely explosive andesite  volcano finally erupted, sending a massive column of ash, smoke and lava up to 20km into the atmosphere.

Chile’s ONEMI emergency office declared a red alert and evacuated more than 4,000 people within a 20km (12 mile) radius of the 2,015-meter high volcano.

Residents of the nearby town of Ensenada and two other communities have been ordered to abandon their homes.

Calbuco’s last major eruption occurred in 1961.

Villarrica volcano, also in southern Chile, erupted in March.

ONEMI has posted the following update (Spanish) on its website:

22 Indonesian Volcanoes Remain on High Alerts

Posted by feww on November 16, 2013

5 Indonesian volcanoes remain on the 2nd highest state of alert, “orange,” 17 others on “yellow”

The alerts follow the latest eruption at Mt Sinabung, which saw the volcano ejecting ash to a height of about 7 km above the summit, forcing the authorities to evacuate about  5,600 people in several villages, according to Indonesia’s Center for Volcanology and Geological Disaster Mitigation (PVMBG).

Indonesian authorities have established a 3-km exclusion zone near the volcano following the Tuesday eruption for the second time in 9 days.

PVMBG had issued a “level three,” or “orange alert,” recommending villagers to stay out of the 3-km danger zone on November 3, 2013, followed by a 7-day state of emergency declared by the local authorities.

The explosive activity follows a series of most recent eruptions exhibited by the 2,460-meter high volcano that began in September 2013, leading to a significant eruption on October 24, which saw the volcano spewing smoke and ash to a height of about 3km above the crater summit, followed by other eruptions, especially the explosive eruption that occurred on Sunday, November 3.

Mt Sinabung is one of 130 or so active volcanoes in the Indonesian archipelago, whose 18,307 islands (922 of the islands are permanently inhabited) straddle the Pacific Ring of Fire (PRF).

PRF, aka the circum-Pacific seismic belt, is home to 452 volcanoes, or more than 75% of the world’s active and dormant volcanoes.

About 90% of the global seismicity and 82% of the largest quakes occur along PRF  [FIRE-EARTH data.]

Mt Sinabung erupted in August 2010 after 410 years of dormancy. The eruption claimed a dozen lives and displaced thousands of others. The eruption which occurred on August 29, 2010 was followed by a more powerful explosion the next day, and much stronger blast on September 7, 2010.

Sinabung spewed ash to a height of about 2km in its second eruption in two days on August 30, 2010.

Indonesian Volcanoes

Indonesian Volcanoes have been responsible for a number of cataclysmic explosions in modern history.

Krakatoa [Krakatau] Cataclysmic Eruption 1883

The Krakatoa eruption affected the climate driving the weather patterns wild for the next 5 years. Average global temperatures fell by about 1.2 °C in the following years, returning to normal only in 1888.

The eruption ejected about 21 cubic kilometers of volcanic matter and destroyed two-thirds of the Krakatoa island. The explosion also spawned giant tsunamis killing an estimated 40,000 people.

Based on their models, our colleagues at EDRO forecast that the collapse of Singapore may occur as a result of volcanic activity on the island of Sumatra. However, they have not disclosed any further detail.

Indonesia Volcano Alerts

PVMBG has placed five volcanoes on the second highest level of activity “Level III, Orange Alert,” and 17 others on  third highest alert level “Level II, Yellow Alert.” Following table shows the alert level designations, as of November 16, 2013.

Sinabung Volcano Explodes

Posted by feww on November 3, 2013

Mount Sinabung in North Sumatra erupts explosively

North Sumatra’s Sinabung volcano erupted explosively early Sunday, ejecting a column of smoke and ash up to 7,000 meters above the summit on November 3, according to Indonesia’s Center for Volcanology and Geological Disaster Mitigation (PVMBG).

Authorities have established a 3-km exclusion zone and are evacuating 4 villages, according to local reports.

The explosive activity follows a series of most recent eruptions exhibited by the 2,460-meter high volcano that began in September, 2013, leading to a significant eruption on October 24, which saw the volcano spewing smoke and ash to a height of about 3km above the crater summit.

Mt Sinabung erupted in August 2010 after 410 years of dormancy. The eruption claimed a dozen lives and displaced thousands of others. The eruption which occurred on August 29, 2010 was followed by a more powerful explosion the next day, and much stronger blast on September 7, 2010.

Sinabung spewed ash to a height of about 2km in its second eruption in two days on August 30, 2010.

Indonesian Volcanoes

Indonesian Volcanoes have been responsible for a number of cataclysmic explosions in modern history.

Krakatoa [Krakatau] Cataclysmic Eruption 1883

The Krakatoa eruption affected the climate driving the weather patterns wild for the next 5 years. Average global temperatures fell by about 1.2 °C in the following years, returning to normal only in 1888.

The eruption ejected about 21 cubic kilometers of volcanic matter and destroyed two-thirds of the Krakatoa island. The explosion also spawned giant tsunamis killing an estimated 40,000 people.

Based on their models, our colleagues at EDRO forecast that the collapse of Singapore may occur as a result of volcanic activity on the island of Sumatra. However, they have not disclosed any further detail.

Indonesia Volcano Alerts

PVMBG has placed five volcanoes on the second highest level of activity “Level III, Orange Alert,” and 6 others at the third highest alert level “Level II, Yellow Alert.” Following table shows the alert level designations together with the last date of eruption, as of November 3, 2013.

Mount Rokatenda Erupts, Kills 6 People

Posted by feww on August 10, 2013

Restive Mount Rokatenda on Palue, Indonesia, finally erupts

Mount Rokatenda, located on the small island of Palue about 2,000km east of Jakarta, erupted spewing ash and rocks more than 2,000 meter into the air.

Hot ash and lava from the eruption fell on a nearby beach, killing at least 6 people including 2 children, officials said.

Rokatenda has been restive since last October, forcing the evacuation of hundreds of villagers.

The eruption started at 04:27 on Saturday (20:27 UTC Friday) and lasted for about 4 hours, according to the National Disaster Mitigation Agency.

=================

Mount Rokatenda is one of about 130 active volcanoes in Indonesia, an archipelago of more than 17,000 islands. Much of the country sits along the Pacific “Ring of Fire,” an area crisscrossed by numerous fault lines and prone to earthquakes and volcanic activity.

Mount Merapi’s 2010 eruption in central Java left up to 400 people dead and more than 250,000 others displaced.

Kamchatka Volcanoes The Fat Lady?

Posted by feww on December 24, 2010

Kamchatka Volcanoes May Be Instrumental to the ‘Epilogue’

Activity at Kamchatka Volcanoes Could Increase Dramatically in the Period Leading to Collapse

There are about 165 volcanoes on Kamchatka Peninsula, 29 of which are still active. About 120 of the volcanoes are believed to have erupted during the Holocene Epoch (approximately 12,000 years ago to present time).

Mayon Volcano Oozes Lava

Posted by feww on December 15, 2009

Mayon, Philippines most active volcano, oozes lava and ejects plumes of ash into the air

The Philippines Institute of Volcanology and Seismology, PHIVOLCS, raised the five-step alert to 3 after increased activity at Mayon volcano.

The authorities have evacuated thousands of residents from the 6-km (4 miles) permanent danger zone, which is now declared a prohibited area.

About 50,000 people live in an 8km (5 mile) radius of the mountain.

About 30,000 people were evacuated from the foot of Mt Mayon after the volcano spewed ash and lava in Albay province, the Philippines.  Photo:AFP. Image may be subject to copyright. Click image to enlarge.

Magma had been steadily rising at Mayon since late November and finally oozed out of the crater late Monday, and the activity at the volcano is expected to intensify, said PHILVOC.

If magma continues to push up the crater at a steady rate there would be lava flows, and “the possibility of an explosion.” PHILVOC reported.


Major Volcanoes of the Philippines Location Map. Click image to enlarge.

The 2467-meter Mayon Volcano is a stratovolcano [it is renowned for its almost perfectly conical shape] islocated about 15 kilometres northwest of Legazpi City [about 500 kilometers south of the capital, Manila,] in the province of Albay, Bicol Region, on the island of Luzon, in the Philippines.

Mayon is one of the 22 or so active volcanoes in the Philippines, and has caused the deaths of thousands of people and devastated several towns and villages in three major eruptions since its 1814. In 2006, after several eruptions, typhoon Durian triggered mudslides of volcanic ash on November 30, which buried  several villages near the foot of the mountain, killing about 1,000 people.

Fire Earth Moderators believe more volcanic activities at other Philippines volcanoes are highly probable in the near future. The volcanoes located on the island on Mindanao are particularly liable to erupt in the next 12 to 36 months.

The moderators also believe a large eruption may occur at Taal volcano. For other related forecast, see links below and search blog contents.

Powerful Quake Strikes Fiji

Posted by feww on November 9, 2009

Another powerful earthquake strikes Fiji – more intense seismic activity could occur in the region this year

A powerful quake measuring up to 7.3 Mw struck Fiji at 17.212°S, 178.413°E or about 100 km north of the capital, Suva and at a depth of 585 km on Monday, November 09, 2009 at 10:45 UTC.

The mainshock was followed by at least one aftershock measuring 5.3 Mw.

On August 19, 2009 FEWW Moderators posted the following entry:

New Round of Geo-Assualt at Kermadec Trench

Following the powerful 7.8 magnitude earthquake that struck the tip of the Fiordland, South island, New Zealand, followed by a large cluster of aftershocks, another round of geo-assault appears to be gearing up at the southern end of the Kermadec trench.

The Fiordland quakes occurred as a result of a large reverse faulting motion caused by the subduction of the Australian subplate under the Pacific plate, on which Fiordland rests,  in Puysegur Trench, at the Alpine Fault.

The new wave of earthquakes would instead be caused by the ‘mirror image’ action, with Pacific plate subducting beneath the Australian protoplate.

A magnitude 6.3 earthquake that struck south of the Fiji Islands on August 18, 2009 at 21:21 UTC may herald a new round of intense [and unprecedented] seismic activity at Kermadec Trench to the north, NE, and East of the North Island, as well as the north, NE, and east of the South Island, New Zealand.

Earthquakes: Human Enhanced Disasters – UPDATE 2 Oct 2009

Posted by feww on October 2, 2009

Sumatra Double Earthquakes

FEWW Moderators believe it’s highly probable that another 2 or more strong to powerful quakes could strike the region in the coming days. Padang and other coastal towns in Sumatra and Java must also prepare for a possible tsunami.

At least 1,200 bodies have been recovered following widespread damage after a magnitude 7.9 quake  struck southern Sumatra, Indonesia, on Wednesday, according to the officials.

The Death Toll Could Reach Many Thousands


There are no reports of deaths from the 6.8 magnitude quake that struck southern Sumatra  on Thursday. However. a local radio station reported that a dozen 12 people had been injured and up to 75 building damaged in  the town of Jambi.

“People are trapped and screaming for help but they are below huge slabs which will take heavy equipment to move,” an aid worker said.

“I saw dozens of the biggest buildings collapsed in town. Most of the damage is concentrated in the commercial center market, which was fully packed,” he said.

Images that will be repeated throughout the world, again, and again

Regional Economy

West Sumatra, a major producer of crude palm oil, is also affected economically.

Indonesia’s finance minister Sri Mulyani said: “This region has been damaged seriously, including its infrastructure,” adding that her government has allocated $25 million over two month for emergency operations.
