just saw article regarding Santorini.
signs of a possible awakening.
Interesting article here bout even more underwater volcanoes than previously thought.
In 1993, marine geophysicists on board the research vessel Melville discovered 1,133 underwater volcanoes not previously been mapped off the coast of Easter Island.
Some of the recently discovered volcanoes are as much as a mile and a half high above the seabed,and tops are a half mile below the surface of the sea, all this in a relatively small area of only 55 square miles, about the size of the State of New York.
Geophysicists have increased the known reserves of underwater volcanoes to more than ten per cent only in a few months.
Today, scientists estimate that there are more than three million submarine volcanoes. Yes that is a three followed by six zeros!
In 2007, oceanographers Hillier and Watts seen 201,055 underwater volcanoes. "From this, they concluded a staggering total of 3,477,403 submarine volcanoes should reasonably exist in the world," said John O'Sullivan in an article.
Hillier and Watts have based their conclusion on the observations of previous and respectable Specialist Science, Batiz (1982) who discovered that at least 4 percent of the seamounts are active volcanoes. "
Batiz According to the survey, half of the Pacific plate alone contains an incredible amount of underwater volcanoes (22000-55000), with at least 2,000 of them considered active.
The Arctic Ocean contains many more previously suspected submarine volcanoes, hydrothermal activity and displays more than scientists had suspected. Look at the Gakkel Ridge.
The Gakkel ridge is a gigantic underwater volcanic mountain range that extends for about 1,100 miles (1,800 km) beneath the Arctic Ocean from north of Greenland to Siberia.
With its 3 miles high summits, Gakkel ridge, the northernmost part of the mid-ocean ridge system, is much more powerful than the Alps
If a volcano is only able to heat a high mountain lake in New Zealand to 108 degrees, imagine what a chain length of 1100 miles of underwater volcanoes could do to the Arctic Ocean.
It does not take much imagination to understand that is why the Arctic is struggling to recover through the polar ice.
Volcanoes are vents of Asphalt on the ocean floor that spew asphalt instead of lava.
They were discovered in the Gulf of Mexico during an expedition of the research vessel SONNE, led by Gerhard Bohrmann of the DFG Research Center Ocean Margins in 2003. In 2007, seven more of these structures have been discovered off the coast of Santa Barbara, California.
The largest of these volcanoes are located at a depth of 213 m.
The structures are larger than a football field and high As a building of six floors, all made entirely of asphalt and also emit large amounts of methane gas.
No need to wonder why so many dead fish came belly up, on the California coast, and in various other parts the world.
Calif. Saudi Arabia Thousands of starfish, crabs and other sea creatures were found dead on a beach in Flintshire North Wales
Currently, June 25, the Chilean volcano is still erupting and a few days after it has entered into a volcano erupting in Eritrea is too "it entered into eruption, ejecting large quantities of ash and SO2 into the atmosphere in which it currently can be seen in the Southern Hemisphere sky, a sign indicating that the coming winter could feel a drastic drop in temperatures at ground level, because the sulfur particles redirecting part of the solar radiation.
It seems that all other volcanoes are showing signs of waking up or having substantial volcanic activity accompanied by a significant increase in seismic activity like Volcano Taal, Philippines, the 'steady increase in the levels of carbon dioxide indicates that magma is rising towards the crater and may cause strong explosions of steam and toxic gases. In the meantime, however a strong earthquake of 6.3 on the Richter scale shook the islands of Santa Cruz, Pacific, just hours after another quake of 7.2 on the Richter scale struck near the Aleutian Islands of Alaska.
In Greece, it seems that Santorini has seen an increase in activity. Seismologists and volcanologists are monitoring closely the seismic sequence that took place in the last week in Santorini. The unusual activity recorded in the volcano Thera 'was caused by magma rising from the bottom of the volcano, increasing the pressure on the cone of crater.The volcanic activity is of short duration, with a slow progression, but in recent weeks the characteristic smell of rotten eggs that emits sulfur, which exists in abundance in the subsoil of a volcanic island, is becoming more intense.
Katla volcano in Iceland, too, occasionally seems to be waking, especially of seismic activity and sooner or later it seems likely that its next eruption could be very intense. If one of them erupted in a violent way this year, the climate will almost certainly reach a situation similar to that before the Industrial Revolution of 1850.
But in Indonesia there is a volcano that has recently begun to cause concern, because a place on its crater lake has started to become a typical reddish color, placing a sign of some type of mineral water that has killed all the fish present.
But back to the submarine volcanic activity, it is appropriate to say that these beasts we find everywhere. In April 2008 one of these was found off Iceland on the Reykjanes Ridge, and it was discovered that a point at which Greenland's ice melt is placed over a volcanic hot spot and it is conceivable that such phenomena may occur even in Antarctica.
Huge plumes of boiling water were also found in the Indian Ocean, one of them on the scale of 70 km in diameter, a scale never seen before.
Researchers have also recently announced the discovery of hydrothermal deep-sea fields in the Arctic Ocean and south Atlantic. The appearance of hydrothermal vents around the world, suggests that they have a much more common than previously thought place in the ocean system and could have a major influence on circulation patterns and ocean chemistry.
6.5 Lake Taupo last night. No damage reports.
Interesting news about Hekla, could it be the next Icelandic volcano to erupt?
Some comments from Jon Frimann :
Breaking news on sky of a 7.9 earthquake off the coast of New Zealand, no reports of a tsunami yet but worrying considering how big it is
Earthquake hits English Channel
The earthquake was the biggest in the area for nearly 300 years
An extremely dangerous shallow earthquake occurred in the border area of Kyrgyzstan, Uzbekistan and Tajikistan at 01:35 AM. Theoretical damage calculations are reporting limited to severe number of victims.
Magnitude : 6.2 UTC Time : Tuesday, July 19, 2011 at 19:35:42 UTC Local time at epicenter : Wednesday, July 20, 2011 at 01:35:42 AM at epicenter Depth (Hypocenter) : 9.2 km
Once again the Daily Mail manage to get/get hold of the most stunning pictures. Etna, this time.
Mount Etna erupting illuminates cathedral
Etna still blowing it's top, eruption levels are actually increasing:
Picked the wrong year to visit Sicily - we were there last year on holidays and all was quiet when we visited Etna, pretty spectacular place all the same, would love to be around there at the moment
Tambora also has had alert level raised to 2. Continuous tremor there for 29/30 Aug.
7.1 in Alaska a while ago.
tsunami warning for the Aleutians.
looks like the warnings have been cancelled.
Tambora raised to alert level 3.
(in Indonesian though!)
