Earthquake swarm reported at another Alaskan volcano

Posted on August 17, 2013 by The Extinction Protocol

August 17, 2013 – ALASKA – Seismic unrest is being reported at another Alaskan volcano. Tanaga is a 5,924-foot (1,806 m) stratovolcano located in the remote Aleutian Range of the U.S. state of Alaska. There have been three known eruptions since 1763. The most recent was in 1914 and produced lava flows. According to the Earthquake Report, a swarm of seven earthquakes have struck near the volcano in the last 24 hours- the strongest of which was a 4.7 magnitude. This may suggest magma intrusion under the volcano.

Number 69: Iceland - A small phreatic eruption seems to have taken place yesterday at the ice-covered Kverkfjoell central volcano. The steam-driven (no fresh magma involved) explosion followed a small glacial flood on 15 August the Kverkjökull glacier released into the Volga river and was probably a result of the pressure release during the flood. –Volcano Discovery [link to theextinctionprotocol.wordpress.com]

Huge lava fountains seen gushing from Jupiter moon
20:56 20 August 2013 by Jeff Hecht

One of the most massive volcanic eruptions in the solar system has been spotted on Jupiter's moon Io – by a telescope perched on a volcano on Earth.

On 15 August the Keck II telescope on Mauna Kea in Hawaii recorded fountains of lava gushing from fissures in the Rarog Patera region of Io. Heated by gravitational squeezing from Jupiter and its other moons, Io is covered in volcanoes that erupt almost continuously. This event is easily in the top 10 yet seen on Io by humans, says Ashley Davies of NASA's Jet Propulsion Laboratory in Pasadena, California.

"We try to look at Io at every opportunity, in the hope of seeing something like this," says Davies. "This time we got lucky." The lava fountains spouted molten rock hundreds of metres above Io's surface, erupting over an area totalling 31 square kilometres...

Iceland Glacial Outburst Causes Steam Explosions

A glacial outburst flood occurred in the river Volga on the edge of Kverkjokull, an outlet glacier in the northern part of Vatnajökull, by the Kverkfjoll mountain range late last week. The flood was accompanied by steam explosions, scattering rocks the size of footballs several hundred meters around the area...
On two locations, Kverkjokull lies on top of high-temperature geothermal areas. They cause glacial water to melt and lagoons to form, which at certain points lift the glacier and flood from underneath it.

“There are indications that a glacial outburst flood occurred from a known lagoon called Gengissigio, which is at an altitude of 1,600 meters (5,250 ft) in the high-temperature geothermal area in Kverkfjoll,” said geophysicist Bjorn Oddsson, project manager at the National Commissioner of the Icelandic Police.

The depression left by the glacial outburst flood is 500 meters in diameter. However, this was considered a minor flood.

“At the bottom of the lagoon we can see brash which had accumulated on the lagoon’s surface and there were also steam explosions in hot springs below the lagoon,” Bjorn said in description of the scene, which he explored from the air on Friday...

Guagua Pichincha volcano
...Following a 100 year long interval of being dormant, Guagua Pichincha volcano has entered a new phase of low seismic, phreatic and magmatic activity in 1981....
Plinian eruptions from Guagua Pichincha
Over the past 2000 years, 3 Plinian eruptions happened at the Guagua Pichincha volcano, in the 1st century AD, in the 10th century, and in AD 1660. The eruptions produced plinian eruption columns of 25-30 km height and left well-defined fallout pumice layers covering the upper slopes of the volcano. The 10th century eruption was the largest, with a VEI of 5.
(C. Robin et al. (2008) "Late Holocene phases of dome growth and Plinian activity at Guagua Pichincha volcano (Ecuador)", Journal of Volcanology and Geothermal Research, 176, pp. 7–15) ...

1660 Plinian eruption of Guagua Pichincha
Quito has been significantly affected several times by eruptions of Guagua Pichincha. The worst of these events occurred in 1660, when as much as 25 cm of ash covered the city. A similar event today, as the its population approaches 2 millions, could spell a major disaster.
The eruption in 1660 began on 28 October 1and lasted for 12 hours. A plinian eruption column developed, reached ca. 25 km altitude and deposited ash and pumice over Quito, which was in a total darkness during the eruption. Pyroclastic flows and surges swept down the flanks of the volcano, but the topographic relief of Rucu Pichincha prevented flows from reaching Quito itself.
The ash fell as far north as Popayan, Columbia (300 km ), and to the south at Loja (430 km ), and to the west it reached the Pacific coast (170 km). Earthquakes during the eruption caused panic in Quito...

Large Explosion at Sakurajima Dusts Kagoshima with Ash
BY ERIK KLEMETTI08.18.138:21 PM

Occasionally, large explosions occur and this weekend, Sakurajima produced one of its largest explosions in decades (possibly the largest since the VEI 4 eruption in 1914; see video above). The eruption plume (see below) from Sunday’s eruption reached 5 km (~16,500 feet) and ash from the eruption spread across nearby Kagoshima (the host of the recent IAVCEI Scientific Assembly), causing some limited visibility and train delays due to the ash fall in the city only 8 km from the summit of Sakurajima. The ash was enough to prompt people to wear dust masks to prevent breathing the hazard volcanic glass shards — remember, volcanic ash is really just pieces of volcanic glass that are shattered by the explosive expansion of bubbles in an erupting magma. Some of the news footage of the eruption shows what might be small pyroclastic flows generated by the explosion as well (thanks to James Reynolds for noting that):

If you want a lot of detail on the history of the recent activity at Sakurajima, check out Boris Behncke’s comment below. Oddly enough, this was also Sakurajima’s 500th eruption of 2013. With this constant activity, Sakurajima is always worth watching on the multitude of webcams pointed at the volcano.

Boris Behncke • a day ago
Here's an interesting presentation (in pdf format) by Masato Iguchi about the recent activity of Sakurajima (through early 2012), which has the hypothesis that the activity might eventually culminate in something major (based on accelerated inflation of the volcano, which is going on in spite of the vigorous eruptive activity):

The balding Arctic
Sea ice retreat through the first half of August was near average, bringing the ice extent to 5.94 million square kilometers (2.30 million square miles). Sea ice extent continues to track well below average levels (average of 1981 to 2010), though remains within two standard deviations of the long-term mean. Retreat rates increased slightly in the western Beaufort Sea and Chukchi Sea, but ice cover remains extensive in those regions compared to 2012. Another major difference between ice extent during 2012 and this year is the much greater extent in the East Siberian Sea. Low ice extent in this region observed last year was in part attributed to the effects of the “Great Cyclone of 2012” (see previous post of August 14, 2012). On the eastern side of the Arctic near Europe and Greenland, the extent remains below average...

...The tendency towards a more open pack, with large areas of open water between ice floes, has increased in the past decade as the ice cover has thinned, as well as a tendency for formation of large polynyas (see ASINA posts for September 2006) and areas of pack detached from the main Arctic ice cover (such as mid-August 2012). The University of Washington’s Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) model and other models of ice thickness continue to indicate thin ice cover this summer...

That high pressure last year over Greenland also contributed to a record melt season for the Greenland ice sheet. Melt this year over the ice sheet has been more moderate, though still above rates seen in the 1990s....

Record extent in the Antarctic
Antarctic sea ice extent for August 19 is 18.70 million square kilometers (7.22 million square miles), a record or near-record high level (August 19, 2010 was similarly high), led by unusually extensive ice in the Bellingshausen, Amundsen, and Ross seas, and in the western Indian Ocean sector...

A submarine eruption has likely occurred this morning in Indonesia. VSI raised the alert level of Iliwerung volcano from 1 (normal) to 2 (watch) following increased seismic and visual activity from an underwater flank vent called Gunung Hobal.
Iliwerung volcano forms a peninsula on the south coast of Lembata (Lomblen) Island (East Indonesia). Mount Hobal (Gunung Hobal) is a submarine flank vent of Iliwerung located about 800 m from the coast. It has had several historic eruptions during which several temporary islands were formed. The latest bulletin of VSI describes that the water around Hobal has recently shown significant color changes to yellow, intense bubbling and white steam plumes rising up to about 1000-2000 m from 7:14 local time this morning. Half an hour later, from 7:46 am, glow even began to be visible.

Some Volcanic Eruptions On Hold Indefinately
AUG 21, 2013 04:02 AM ET // BY TIM WALL

Detecting a pocket of magma doesn’t necessarily mean a volcanic eruption is imminent. Magma may hang out near the surface of the Earth for hundreds of thousands of years before exploding out in an eruption, according to new research...

Understanding how long a magma reservoir can remain liquid could improve geologists ability to assess the risk from particular deposits.

“If you see melt in an area, it’s important to know how long that melt has been around to determine whether there is eruptive potential or not,” Gelman said. “If you image it today, does that mean it could not have been there 300,000 years ago? Previous models have said it couldn’t have been. Our model says it could. That doesn’t mean it was there, but it could have been there.”

Landslide-Tsunami

Landslide events within the ocean can be far larger than those on land and often generate tsunami events that can devastate coastlines thousands of miles distant. There have been several large submarine landslides in the Arctic in the last 20,000 years, the largest of which occurred off the coast of Norway and saw a volume of sediment collapse that would cover Scotland to a depth of 260 feet. The resulting tsunami is thought to have devastated Mesolithic human cultures living on the eastern shores of England and Scotland and may have destroyed a land bridge between England and Denmark...

[link to arp.arctic.ac.uk]

...Supplementing observations with models of the impact of current and future changes in the Arctic will yield a better understanding of the nature and magnitude of the risk to the UK of a major tsunami being initiated by an Arctic submarine landslide.

Given the timings of past slides, there is already a 5% probability of a major landslide occurring in the next 200 years. However, LANDSLIDE-TSUNAMI’s research is set to become even more relevant as the climate changes occurring in the Arctic could significantly increase this risk of large landslides and tsunamis. Rapid warming now being observed in Arctic waters could cause dissociation (breakdown through thawing) of gas hydrates (crystalline ice structures) buried in marine sediments so releasing the greenhouse gas methane previously trapped in the hydrate structure. This release of methane could be significant for climate change if it reached the atmosphere but the gas bubbling could also cause vast areas of sediment to slide catastrophically. A further means to destabilise marine sediment slopes is through the weight of ice sheets and glaciers being removed from parts of the Earth’s crust because of rapid ice melt which would trigger rebound and uplift of the depressed crust that was under the ice and cause earthquakes in the process.

Suphan Dagi is a 4158-m-high basaltic-to-rhyolitic stratovolcano located immediately north of Lake Van. A glacial icecap mantles the summit of the volcano, the 2nd highest in Turkey. During construction of the volcano andesitic-dacitic lava flows alternated with fluid basaltic flows, followed by construction of a large lava dome over the central vent. The flanks of the volcano are dotted with numerous lava domes and pyroclastic cones erupted along radial and circumferential fissures, particularly on the northern, souther, and eastern sides. The 1.5-km-wide, low-rimmed Aygirgolu maar was erupted on the lower southern flank. During the latest stage of activity, voluminous basaltic lava flows traveled as far as 30 km from the summit. Potassium-Argon dates for Süphan Dagi range from 2 to about 0.1 million years, but the latest basaltic eruption occurred about 10,000 years ago (Yilmaz et al., 1998).
