Yowbarb Note: Long dormant volcano Rokatenda came back to life last year and there was a fatal eruption on Sat. Aug 11th 2013

http://www.thejakartaglobe.com/news/villagers-ignore-evacuation-warnings-as-mount-rokatenda-erupts/

Disaster agency officials struggled to convince villagers on the tiny island of Palue to evacuate their homes as Mount Rokatenda continued to erupt on Monday, spewing hot ash and endangering the residents of five villages reportedly bound to their ancestral land by local tradition.

“Out of the 5,315 people living inside the danger zone, only 2,754 have been evacuated,” Eduardus Desa Pante, the executive director of the Sikka District Disaster Mitigation Agency, told Kompas.com. “We will continue to approach them and try to persuade them [to leave].”

Mount Rokatenda, in East Nusa Tenggara, erupted on Saturday, sending clouds of hot ash nearly 2,000 meters into the air and killing five people as torrents of molten lava poured down the volcano’s slopes. The eruption appeared to subside on Monday, but five villages dotting the slopes of the mountain — Rokirole, Lidi, Nitunglea, Ladolaka, and Tuanggeo — remained in a three-kilometer danger zone.

Surono, head of the state volcanology center, warned: “The volcano still has the potential to erupt again.

“Rokatenda remains a threat for those living inside the three-kilometer zone.”

Nearly half of the local residents have ignored both government pleas to abandon their homes and the danger of the erupting volcano, telling disaster agency officials that local customs demand they remain on their ancestral lands.

Evacuation efforts began in force on Sunday as crews helped more than 500 people escape to the nearby Flores island, according to reports by Agence France-Presse. Disaster crews trudged through thick ash to reach the affected villages, often finding residents scared but reluctant to leave.

“Everything was burnt by the lava,” Eduardus said on Sunday. “People were scared and many were crying. They wanted to get away from the volcano but at the same time they were reluctant to leave their livestock and homes.”

Those who have so far left the island are some of the 3,000 people in need of evacuation following the eruption, said Sutopo Purwo Nugroho, spokesman for the national disaster agency.

Officials still hope to evacuate the remaining 2,500 people in the zone.

Bakri Kari, a member of the rescue team, said two boats were being used to transport those affected off the island.

However, rescue efforts were proving difficult as “a lot of infrastructure has been damaged”, he said. “The main bridge… was destroyed, so it’s difficult to reach the displaced [residents].”

The long-dormant volcano rumbled back to life last year, prompting local officials to set up a permanent exclusion zone near the mountain’s peak.

Some 2,000 people had already been evacuated to Flores before Saturday’s eruption, leaving around 8,000 people still on the island.

Indonesia has more than 100 active volcanoes and straddles major tectonic fault lines known as the “Ring of Fire” between the Pacific and Indian oceans.

The country’s most active volcano, Mount Merapi in central Java, killed more than 350 people in a series of violent eruptions in 2010.

I see three vents at the Turrialba Volcano. 08:16 AM CT there in Costa Rica.
I'm not sure if this has happened before since I haven't done much viewing on the cam, lately.

paroxysmal eruption with strombolian explosions and lava flow at Pacaya volcano, Guatemala

Posted by Adonai on August 16, 2013 in category Volcanoes

Another paroxysm with strong strombolian explosions and a lava flow occurred on the evening of August 15, 2013 from the Mackenney Crater at Pacaya volcano, Guatemala. Starting at about 19:15 (local time), eruptive activity increased accompanied by volcanic tremor. Strombolian explosions ejected bombs and blocks to a height of 500 m above the crater and showered the outer flanks.

VAAC Washington issued a bulletin but was unable to identify the height of the ash plume from satellite data. Ash fall was reported from nearby villages such as El Rodeo and El Patrocinio. At the height of the eruption, a lava flow issued from the west flank and reached a distance of 500 m (VD).

As a safety measure, 32 people from the village of San Francisco de Sales on the SW base of the volcano were evacuated to shelters in San Vicente Pacaya on the northwest side.

After about 2 hours, activity started to wane again.

INSIVUMEH reported that during August 7 - 8 white vapor plumes rose 200 m above Pacaya and drifted E. On August 9 seismicity increased, and strombolian explosions ejected tephra 200 m above MacKenney Crater and onto the flanks, 400 m away from crater. The next day the number and magnitudes of explosions increased, and seismic signals indicating fluid movement were recorded.

Tephra was again ejected 400 m away from MacKenney Crater, causing small avalanches of volcanic material on the flanks. On 12 August fumarolic plumes rose 50 m. Cloud cover prevented observations of the crater on August 13; however, the seismic network recorded a few gas explosions and tremor.

Featured image: Long-term strombolian eruptions began at Pacaya volcano in 1965 and continued for more than a quarter century. Nighttime incandescent explosions are often visible from Guatemala City, 40 km to the north. The accumulation of ejecta from frequent strombolian eruptions periodically raises the height of MacKenney cone after it has been partially destroyed by intermittent larger explosions. This November 1988 photo also shows a lava flow from a fissure on the west flank of MacKenney cone descending the right-hand skyline. Photo by Lee Siebert, 1988 (Smithsonian Institution).

Suwanose-jima  | Japan  | 29.635°N, 129.716°E  | Elevation 799 m

According to the Tokyo VAAC, the JMA reported that on 28 August pilots observed ash plumes from Suwanose-jima that rose to altitudes of 3-3.7 km (10,000-12,000 ft) a.s.l. and drifted E and NW. Explosions during 28-29 August generated ash plumes that rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted NE. Ash was detected in satellite images on 29 August, and explosions were detected on 30 August and 1 September.

Most oceanic plateaux are massive basaltic volcanoes. However, the structure of these volcanoes, and how they erupt and evolve, is unclear, because they are remote and submerged beneath the oceans. Here we use multichannel seismic profiles and rock samples taken from Integrated Ocean Drilling Program core sites to analyse the structure of the Tamu Massif, the oldest and largest edifice of the Shatsky Rise oceanic plateau in the north-western Pacific Ocean. We show that the Tamu Massif is a single, immense volcano, constructed from massive lava flows that emanated from the volcano centre to form a broad, shield-like shape. The volcano has anomalously low slopes, probably due to the high effusion rates of the erupting lavas. We suggest that the Tamu Massif could be the largest single volcano on Earth and that it is comparable in size to the largest volcano in the Solar System, Olympus Mons on Mars. Our data document a class of oceanic volcanoes that is distinguished by its size and morphology from the thousands of seamounts found throughout the oceans.

Sumatra Volcano Eruption Forces Thousands To Flee Homes

By BINSAR BAKKARA 09/16/13 04:47 AM ET EDT AP

MEDAN, Indonesia -- Nearly 6,000 people were evacuated from their villages following the eruption of Mount Sinabung in western Indonesia, an official said Monday.

The 2,600-meter (8,530-feet) volcano in North Sumatra province erupted early Sunday after being dormant for three years, sending thick ash into the sky with small rocks pelting neighboring villages, said National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho. He said almost 6,000 people have been evacuated and were being sheltered in seven locations. No injuries or damage was reported.

Most of the displaced were from six villages within 3 kilometers of the mountain in Karo district, Nugroho said.

Local authorities prepared 2,000 blankets and distributed masks to displaced people. They also have set up a health command post, Nugroho said.

On Monday, gray smoke still billowed from the peak of North Sumatra's tallest volcano, carrying ash eastward. Authorities asked residents to remain alert for other potential eruptions.

Bambang Ervan, spokesman of the Transportation Ministry, said Monday that the eruption delayed six flights at Kualanamu airport in the provincial capital of Medan on Sunday, but operations returned to normal Monday.

Mount Sinabung's last eruption in August 2010 killed two people and forced some 30,000 people to flee. It caught many scientists off guard because they had failed to monitor the volcano, which had remained quiet for four centuries.

There are more than 129 active volcanoes in Indonesia, the world's largest archipelago nation. It is prone to seismic upheaval due to its location on the so-called "Ring of Fire" – a series of fault lines stretching from the Western Hemisphere through Japan and Southeast Asia.

Seven Volcanoes In Six Different Countries All Start Erupting Within Hours Of Each Other
Update from Chris Carrington: Seven Volcanoes Article: Your Questions Answered

Chris Carrington
Activist Post

A new island has appeared in the Pacific. A submarine eruption just off Nishino-Shima Island Japan has erupted for the first time in 40 years. The Japanese Navy noticed the explosions as boiling lava met sea water giving rise to plumes of steam and ash.

Almost 7,000 miles away in Mexico, the Colima volcano blew its top after a period of relative calm. A steam and ash cloud rose two miles into the sky and the grumbling of the mountain could be heard in towns a few miles away.

In Guatemala the ‘Fire Mountain’ belched out lava and sent up a moderate ash cloud causing an ash fall over nearby towns. The explosions and shock waves occurring in the volcano can be felt by residents over 6 miles away. Doors and windows are reported to be rattling, but there has been no damage so far.

In Vanuatu the Yasur volcano is giving some cause for concern. Although the explosions are quite weak the continuous ash that is coming from the mountain is starting to build up on farming land.

Over to Italy, Mount Etna is putting on quite a display. The current eruption started a few days ago and has been getting stronger as time moves on. A massive eruption lit up the sky and disturbed residents yesterday. The ash cloud was high enough to see flights canceled. The lava flow was the biggest in years, and the town of Zafferana which lay in its path saw some damage. Lava diverters were put into place, and most of the town escaped unscathed.

The Etna eruption (Nov 17th)

In Indonesia a four mile high ash cloud is making life hard for residents. Mount Sinabung came back to life in 2010 after dormancy of hundreds of years. Occasionally coming to life after its 2010 awakening, the rumbling of the volcano prompted the evacuation of over 6000 people as scientists feared a major eruption. There has been no lava flows so far but the ash cloud is growing.

Mount Sinabung ash cloud

Still in Indonesia but on the island of Java this time, Mount Merapi exploded yesterday. Hundreds of people were killed when it last erupted in 2010. There is no news of casualties at this point.

So, we have eruptions big enough to prompt evacuations. Flights are canceled, and a new island pops up off the coast of Japan. I would have called that newsworthy myself but obviously I’m wrong. If I was right it would have been common knowledge right? Reports may have been on the news right?

So many volcanoes throwing so much gas, ash and particulates into the air can have an effect on climate, this is a scientific fact. I’m not saying that these volcanoes herald the start of a new ice age but the planet certainly seems to be getting a bit more active of late.

Continued large eruptions put a huge amount of particulate matter into the atmosphere, and these particles reflect sunlight away from earth and when there is enough of them the temperatures can drop.

The Mount Pinatubo eruption lowered temperatures by around 0.5°C across the Northern Hemisphere.

Considering that we are in a cooling period anyway, having so many volcanoes going off at the same time is not good. Aside from the devastating effects the lava and ash can have on the lives of those living near to them, the global impacts can be enormous.

Lost crops due to ash fall and lower temperatures can lead to hunger and famine, as happened after the Tambora eruption in 1815.

Economic losses due to lost crops and canceled flights runs into millions of dollars a day, as with the Icelandic eruption of Eyjafjallojkull (pronounced: aya fiat la u cud la) in 2010.

The spasms of the earth come without warning, but at the same time those spasms should be a wake up call to all of us that change can happen in the blink of an eye.

Better be prepared for it.
