Halmahera, Indonesia: Ash cloud 800 meter high at Dukono volcano

Armand Vervaeck
Earthquake Report
Wed, 07 Sep 2011 10:28 CDT


Dukono volcano (North Halmahera regency, Indonesia) activity increased on September 6, 2011 in sending volcanic ash clouds as high as 800 meters in the sky. The capital town of the Halmahera regency lies at the port of Tobelo, approx. 15 km from the volcano (population approx. 15,000). Residents were asked to evacuate at least about two kilometers from the foot of the volcano.

The volcano observation post at Mount Dukono, told the press that dozens of volcanic earthquakes occurred every day.
The eruption can be seen from Ternate, and island and biggest city in the area (has also an airport).

The volcano is currently in PVMBG Alert status III (local sources) although the official PVMBG site is still showing a II alert status (alert status range from 1 to IV). North Halmehara is part of the province of North Maluku (Moluccas)



Dukono, Halmahera, Indonesia - satellite map ; summit elev. 1335 m

Activity of the volcano as written in our report of the first half of August :
According to a news article, activity at Dukono has continued to increase. On 11 August ash explosions were audible within a radius of about 7 km from the base of the volcano. Ash was ejected as high as 1 km above the crater, producing plumes that drifted E and S, and also approached Tobelo City (14 km ENE). Seismographs at the Dukono observation post recorded more than 100 eruption earthquakes. Based on analyses of satellite imagery, the Darwin VAAC reported that on 11 and 14 August ash plumes rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted 93 km NW.

Reports from this remote volcano in northernmost Halmahera are rare, but Dukono has been one of Indonesia's most active volcanoes. More-or-less continuous explosive eruptions, sometimes accompanied by lava flows, occurred from 1933 until at least the mid-1990s, when routine observations were curtailed. During a major eruption in 1550, a lava flow filled in the strait between Halmahera and the north-flank cone of Gunung Mamuya. Dukono is a complex volcano presenting a broad, low profile with multiple summit peaks and overlapping craters. Malupang Wariang, 1 km SW of Dukono's summit crater complex, contains a 700 x 570 m crater that has also been active during historical time.

US, Alaska: Remote Alaska Volcano Resumes Dome Growth


Associated Press

The lava dome at a remote Alaska volcano has resumed growing, prompting officials to raise its alert level.

The dome now fills the floor of the crater at Cleveland Volcano, 940 miles southwest of Anchorage.

The Alaska Volcano Observatory on Tuesday raised the volcano's alert level to watch status. The threat level was dropped on Aug. 30, but raised against after a persistent thermal anomaly started Saturday. Observatory officials say in a news release that's when the lave dome likely started growing again.

The dome was 262 feet in diameter on Aug. 30, but is now about 394 feet in diameter.

Officials say if that continues, lava flows could start on the flanks of the volcano. The growing dome also increases the possibility - but doesn't ensure - an explosive eruption.

No Imminent Eruption Risk in Iceland's Volcano Katla
There are no definite signs of an imminent eruption in the sub-glacial volcano Katla in south Iceland although regular series of minor earthquakes and increased geothermal heat indicate that the volcano is expanding. Katla remains under close observation.

Scientists and the Department of Civil Protection have concluded that while there is no imminent risk of a volcanic eruption, these may be long-term indications that the volcano is preparing to erupt. However, similar events have occurred before without them leading to an eruption, Morgunbladid reports.
“People are very calm about it. There will be a public meeting in Vík on Monday with Magnús Tumi [Gudmundsson, geophysicist],” said Kjartan Thorkelsson, chairman of the Civil Protection Committee of the counties Rangárvallasýsla and Vestur-Skaftafellssýsla.
“The Department of Civil Protection will also meet on Monday and decide what happens next, what we take from the public meeting. We are well prepared if Katla were to erupt,” he added.
Ingi Már Björnsson, farmer at Sudur-Foss in Mýrdalshreppur, agreed that locals are calm. “I was born and raised here and one has always dismissed talk of Katla being on the verge of erupting, though I find these circumstances a little different than before.”
“One is a bit more conscious and has more belief that something like this could happen after the share that we’ve had here,” Björnsson added, referring to the three volcanic eruptions that have hit south Iceland in the past three years: Fimmvörduháls in March 2010, Eyjafjallajökull in April 2010 and Grímsvötn in May 2011.
“It would be best for the agriculture and tourism industry if the eruption were to start in the autumn. The ideal time would be November when the slaughter season is behind us and all the livestock is inside. None of the highland pastures have been herded yet so it wouldn’t be good if a volcanic eruption were to start now,” Björnsson concluded.
Sheep herding and roundup in south Iceland will begin next weekend.

Event: Earthquake
Location: Canary-Islands (Esp.) Province of Las Palmas Agüimes

Situation:

Fears are growing that the El Hierro volcano in The Canary Islands could soon erupt after seismic activity beneath the island increased dramatically during Tuesday and Wednesday. Over 150 earthquakes were recorded on the smallest of the Canary Islands during Tuesday prompting officials to evacuate some local residents, shut El Hierro's main tunnel, and close local schools. At least 20 earthquakes, exceeding magnitude 3.0 on the Richter Scale, have been felt by local residents during the last 24 hours. The most recent earthquake, which measured 3.4 magnitude, was recorded just off the southern tip of the island at 07:04 am Wednesday. The rise in seismic activity last night prompted the Spanish Civil Guard (Guardia Civil) to advise almost 50 residents of the municipality of La Frontera to leave their homes because of landslide fears.

Plans are also underway to evacuate more of the island's 10,000 residents, according to Canarias7.es. The newspaper reported that two units of the Spanish military's emergency intervention unit (EMU) will depart nearby island Tenerife this afternoon to assist in the possible evacuation of hundreds of El Hierro residents. Meanwhile, the island's main tunnel (Tunel del Golfo), which links Frontera to Valverde, has been shut forcing motorists to travel across the 280-sq-km island via a mountain road. The Cabildo de El Hierro also has ordered the closure of schools on Wednesday. Hierro, a shield volcano, has had a single historic eruption from the Volcan de Lomo Negro vent in 1793. The eruption lasted approximately one month and produced lava flows. The Canary Islands Government commenced an in-depth geological survey of El Hierro earlier this month in an effort to determine the source of an earthquake swarm. The Government raised the volcanic risk level to ‘Yellow' on Sunday, the highest alert status since an unprecedented earthquake swarm commenced in mid-July.

The unprecedented seismic activity commenced on 19 July (the activity was first reported by iWeather Online on 26 July). In excess of 8,200 earthquakes have been recorded up to Wednesday, 28 September 2011. Up to last weekend, the majority of earth tremors ranged between 1 and 3 magnitude. However, the majority of quakes are now registering between 2 and 4 magnitude and are occuring at depth of 14-17 kilometres, according to the National Geographic Institute (IGN). Speaking to the El Pais newspaper, volcanologist Juan Carlos Carracedo suggested that an eruption on El Hierro would "not be a major surprise". He explained: "It is the youngest of the Canary Islands. There is a ball of magma which is rising to the surface and it is stationed at the limit of the earth's crust. At the moment we do not know if that ball of magna will break the crust and cause an eruption." IGN Director, María José Blanco said that any eruption on El Hierro would most likely have a "low explosion value". He added that an imminent eruption is unlikely. In the meantime, the frequent and increasingly intense earthquakes being felt throughout El Hierro are unlikely to appease the residents of and visitors to the tiny island.

Earthquake swarms are events where a local area experiences sequences of many earthquakes striking in a relatively short period of time. The length of time used to define the swarm itself varies, but the United States Geological Survey (USGS) points out that an event may last for days, weeks, or months. El Hierro is situated in the most southwestern extreme of the Canaries. The island was formed after three successive eruptions, and consequent accumulations, the island emerged from the ocean as an imposing triangular pyramid crowned by a volcano more than 2,000 metres high.

The volcanic activity, principally at the convergence of the three ridges, resulted in the continual expansion of the island. A mere 50,000 years ago, as a result of seismic tremors which produced massive landslides, a giant piece of the island cracked off, crashed down into the ocean and scattered along the seabed. This landslide of more than 300km3 gave rise to the impressive amphitheatre of the El Golfo valley and at the same time caused a tsunami that most likely rose over 100 metres high and probably reached as far as the American coast.

According to the Global Volcanism Program, the massive Hierro shield volcano is truncated by a large NW-facing escarpment, seen here from the east, which formed as a result of gravitational collapse of the volcano. The steep-sided 1500-m-high scarp towers above a low lava platform bordering 12-km-wide El Golfo Bay, which is barely visible at the extreme left. Holocene cones and flows are found both on the outer flanks and in the El Golfo depression. The last eruption, during the 18th century, produced a lava flow from a cinder cone on the NW side of El Golfo.

According to ElHierro.com: "Although over 200 years have elapsed since the last eruption, El Hierro has the largest number of volcanoes in the Canaries with over 500 open sky cones, another 300 covered by the most recent outflows, and some 70 caves and volcanic galleries, notably the Don Justo cave whose collection of channels surpasses 6km in length." El Hierro is located south of Isla de la Palma (population 86,000), currently the most volcanically active of the Canary Islands. About a half a million years ago, the volcano, Taburiente, collapsed with a giant landslide, forming the Caldera de Taburiente. Since the Spanish occupation, there have been seven eruptions.

Orbiting instruments such as the Advanced Land Imager (ALI) aboard Earth Observing-1 (EO-1), which acquired these images, may be the only reliable way to monitor Nabro. The images show the volcano in false-color (first) and natural-color (lower second) on September 28, 2011. Heat from vents in Nabro’s central crater is visible as a red glow in the false-color image. Another hotspot about 1,300 meters (4,600 feet) south of the vents reveals an active lava flow. A pale halo surrounding the vents indicates the presence of a tenuous volcanic plume. South of Nabro’s crater, the dark, nearly black areas are coated with ash so thick it completely covers the sparse vegetation. On either side of this region is a thinner layer of ash with some bright green vegetation (exaggerated in false-color) poking through. In the natural-color image, the arid landscape is light brown where it is not covered by ash. The ash is black, while a fresh lava flow, spewed out in the last two weeks of June, is dark brown. More fresh lava flows surround the active vents. On either side of Nabro’s caldera, ephemeral streams have washed away the ash, leaving light-colored channels behind—a first sign of the erosion that will reshape, and eventually remove, what the eruption built.

Indonesia: Anak Krakatau Raised To Highest Alert Status- Quakes Are Now Continuous, Warn Officials

Gunung Anak Krakatau


Indonesian officials have raised the status of one of its most dangerous volcanoes, Anak Krakatau, to a "standby" or level IV- the highest level.

The Center for Volcanology and Geological Hazard Mitigation (PVMBG), Surono said this is a rise in status that was set on Friday, September 30, 2011 evening at 24.00. The reason for the elevated status is because of the high-intensity level of earthquakes.

Today, for example. "On October 2, 2011, at 00.00 until 12.00, there are 2745 recorded seismic events," said Surono, when he was contacted by VIVAnews.com, Sunday, October 2, 2011. Earthquakes under Mount Anak Krakatau, Surono added, were even felt all along the island of Anak Krakatau.

"The swarm of tremors are continuous and although small, 2 on the Richter scale, they are cause for concern because they are felt constantly," he added. He explained, almost since 2007, Krakatau has been stirred by unrest. "In a moment, it stopped, and erupted in 2009. I think this mountain is always in danger of erupting," he added. - Viva News (translated)

Volcanologist Brad Scott says this is because the temperature of the crater lake is cooler, which tends to produce more gas. The latest Volcanic Alert Bulletin says the lake's temperature on 29 September was 17.6 degrees Celsius. In March, the temperature peaked at 41 degrees Celsius. Mr Scott says the lake is heading towards a temperature where volcanic activity typically occurs, but doesn't always.

Situation Update No. 8
On 2011-10-04 at 13:10:07 [UTC]

Event: Earthquake
Location: Canary-Islands (Esp.) Province of Las Palmas Agüimes



Number of Evacuated: 10000 person(s)


Situation: The Instituto Geografico Nacional (IGN) has reported surface deformations exceeding 35mm on the Spanish island of El Hierro, where residents have been alert for a possible volcanic eruption. The number of earthquakes recorded since July 17 on the smallest of The Canary Islands exceeded 9250 on Tuesday morning.



IGN confirmed on Monday that 1172 earthquakes were recorded last week, the majority of which were located in the sea to the SW of the 280-sqkm island. 52 of the earthquakes were felt by the local population, estimated to be approximately 10,000. A further 10 earthquakes, exceeding 3.0 magnitude on the Richter Scale, were felt during Monday and early on Tuesday.



Hierro, a shield volcano, has had a single historic eruption from the Volcan de Lomo Negro vent in 1793. The eruption lasted approximately one month and produced lava flows. The recent surge in the number and intensity of earthquakes prompted officials from the IGN and The Canary Islands Government to raise the alert level for the Hierro volcano to ‘Yellow’ late last month. Seismologists say the majority of the earthquake activity has shifted from El Golfo in the island’s northwest to beneath the Las Calmas Sea in the south.

However, magma is now on the move upwards while the depth of earthquakes has become increasingly shallow in recent days with most being recorded at a depth of 10 to 14 kilometres.



Movement of magma towards the surface signifies that a volcanic eruption is likely to happen, but the timing of such remains unclear. Volcanologist Juan Carlos Carracedo last week suggested that an eruption on El Hierro would "not be a major surprise".



He explained: "It is the youngest of the Canary Islands. There is a ball of magma which is rising to the surface and it is stationed at the limit of the earth’s crust.



At the moment we do not know if that ball of magna will break the crust and cause an eruption." IGN Director, María José Blanco said that any eruption on El Hierro would most likely have a "low explosion value". A dramatic rise in recorded earthquakes on El Hierro last Tuesday prompted officials to evacuate some local residents, shut El Hierro’s main tunnel, and close local schools. The Spanish Civil Guard (Guardia Civil) advised almost 50 residents of the municipality of La Frontera to leave their homes because of landslide fears. Two units of the Spanish military’s emergency intervention unit (EMU) were also placed on standby to depart the nearby island of Tenerife to assist in the possible evacuation of hundreds of other El Hierro residents.

Meanwhile, the island’s main tunnel (Tunel del Golfo), which links Frontera to Valverde, was shut forcing motorists to travel across the 280-sq-km island via a mountain road. The Cabildo de El Hierro also ordered the closure of schools on Wednesday. El Hierro is situated in the most southwestern extreme of the Canaries. The island was formed after three successive eruptions, and consequent accumulations, the island emerged from the ocean as an imposing triangular pyramid crowned by a volcano more than 2,000 metres high. The volcanic activity, principally at the convergence of the three ridges, resulted in the continual expansion of the island. A mere 50,000 years ago, as a result of seismic tremors which produced massive landslides, a giant piece of the island cracked off, crashed down into the ocean and scattered along the seabed. This landslide of more than 300km3 gave rise to the impressive amphitheatre of the El Golfo valley and at the same time caused a tsunami that most likely rose over 100 metres high and probably reached as far as the American coast.

According to the Global Volcanism Program, the massive Hierro shield volcano is truncated by a large NW-facing escarpment, seen here from the east, which formed as a result of gravitational collapse of the volcano.



The steep-sided 1500-m-high scarp towers above a low lava platform bordering 12-km-wide El Golfo Bay, which is barely visible at the extreme left. Holocene cones and flows are found both on the outer flanks and in the El Golfo depression. The last eruption, during the 18th century, produced a lava flow from a cinder cone on the NW side of El Golfo. According to ElHierro.com: "Although over 200 years have elapsed since the last eruption, El Hierro has the largest number of volcanoes in the Canaries with over 500 open sky cones, another 300 covered by the most recent outflows, and some 70 caves and volcanic galleries, notably the Don Justo cave whose collection of channels surpasses 6km in length." El Hierro is located south of Isla de la Palma (population 86,000), currently the most volcanically active of the Canary Islands. About a half a million years ago, the volcano, Taburiente, collapsed with a giant landslide, forming the Caldera de Taburiente. Since the Spanish occupation, there have been seven eruptions.

Event: Volcano Eruption
Location: Canary-Islands (Esp.) Island of El Hierro Underwater volcano (unnamed)

Situation: Two new volcanic eruptions were confirmed on Wednesday near Spain's El Hierro island in the Canaries, where 500 people spent another night outside their homes after being evacuated as a precautionary measure. "I confirm the existence of two points of volcanic eruption at El Hierro," Laura Otero, a spokeswoman for the local authorities, told AFP, adding that there were dead fish and a strong odor of sulfur at both sites. The head of emergency services in the Canaries, Juan Manuel Santana, said in a statement that "the two points are located at two nautical miles and 1.5 miles southwest of (the village of) La Restinga". The first eruption occurred at a depth of 2,300 feet and the other at a depth of 655 feet. He said the eruptions "resulted in two stains on the sea surface where there are dead fish and a strong odour of sulfur." Some 500 residents and tourists were evacuated from the village of La Restinga as a precautionary measure on Tuesday after a 4.3-magnitude quake the previous day, the first volcanic euption in the Canaries in 40 years. Monday's eruption was detected 3 miles from the island at a depth of between 1,640 and 3,940 feet beneath the sea. Experts had said the eruption would not be felt on the island. Most of the evacuees have found refuge with relatives or friends in other villages on the island. But dozens of others, mostly tourists, spent the night in a student dormitory and a local gym. Pointing to "uncertainty over the coming days", authorities said in a statement that they were keeping Restinga on "red alert", while the rest of the island remained on yellow alert, one notch lower. "It is recommended to exercise caution," said Paulino Rivero, head of the Canaries administration. But he said people would be able to return to their homes under the protection of civil safety officials to retrieve medicines or clothes. Rivero said scientists had noticed no significant changes since Tuesday afternoon. El Hierro, which means iron in Spanish, is the smallest of Spain's Canary Islands, located in the Atlantic off the coast of Morocco. Perched atop an ancient volcano, the island of Hierro has undergone some 10,000 tremors since July 19, the vast majority of them not felt by its 11,000 residents. The last volcanic eruption on the Canary Islands was on nearby La Palma in 1971.

Situation Update No. 3
On 2011-10-22 at 18:36:32 [UTC]

Event: Volcano Eruption
Location: Canary-Islands (Esp.) Island of El Hierro Underwater volcano (unnamed)



Situation: Residents of the village of La Restinga on the island of El Hierro were allowed on Saturday to return to their homes,as the risk of a volcanic eruption subsides. Although the stain in the sea caused by sulphur emitted by the underwater volcano off the coast of the most westerly of the Spanish controlled Canary Islands now surrounds much area of the island, indicators point to the eruption losing strength.



As a result the residents of La Restinga, the village closest to the site of the eruption began to return to their homes on Friday night. They had previously been allowed to make only a brief return to their houses in order to collect essential possessions. The permission to allow the residents to return to their village, which has an economy based on tourism and fishing, comes in the wake of explanations by Spanish scientists on Thursday. Carmen Lopez, of the Spanish National Geographic Institute and Joan Marti of the Board of Scientific Investigation said that the eruption was less powerful than first predicted. Early predictions had spoken of a four stage eruption resulting in magma expelled to the surface creating a new island. That now looks a remote possibility after Lopez said indicators such as the strength and depth of earth tremors have been falling and there has been an overall decrease in seismic activity. Marti was more cautious and said that although it could be that an eruption with various phases could still happen, there was no evidence to show that it was the case in El Hierro. He said event will eventually turn out to be an underwater eruption like many others in the region, which is situated close to a fault line in the Atlantic Ocean. Scientists will now continue to monitor the situation until readings return to the normal levels seen until July when seismic activity was first detected.
