Giant 'balloon of magma' inflates under Santorini
A new survey suggests that the chamber of molten rock beneath Santorini's volcano expanded 10-20 million cubic metres – up to 15 times the size of London's Olympic Stadium – between January 2011 and April 2012.

The growth of this 'balloon' of magma has seen the surface of the island rise 8-14 centimetres during this period, a team led by Oxford University scientists has found. The results come from an expedition, funded by the UK's Natural Environment Research Council, which used satellite radar images and Global Positioning System receivers (GPS) that can detect movements of the Earth's surface of just a few millimetres.

The findings are helping scientists to understand more about the inner workings of the volcano which had its last major explosive eruption 3,600 years ago, burying the islands of Santorini under metres of pumice. However, it still does not provide an answer to the biggest question of all: 'when will the volcano next erupt?'

The late Bronze Age event was a Plinian eruption of epic proportions, with an estimated Volcanic Explosivity Index (VEI) of 6.9. The immensity of this eruption is equaled or surpassed by only seven other terrestrial eruptions in the past four millennia.

Greek Santorini Volcano Runs Risk of First Eruption in 70 Years

Greece’s Santorini Volcano, the site of an eruption 3,600 years ago that wiped out Minoan settlements on the island and in Crete, has begun to fill with molten rock, expanding the most since its last eruption from 1939 to 1941.

...

Studies at the volcano “strongly suggest that the present episode of volcanic inflation is the only significant one since the eruption of 1939-1941, or shortly thereafter,” the researchers wrote. “It would be unwise to assume that the present state of unrest will not end in an eruption.”

...

Santorini alternates between explosive eruptions that occur every 10,000 to 30,000 years and smaller, more frequent dome- forming eruptions separated by as little as 14 years, according to the paper. The volcano had its last “significant” eruption about 70 years ago, the authors said.

“If the present rate of inflation were to continue for a small number of years, the intruded volume would be equivalent to the volumes of previous eruptions,” the researchers said.

3,600 years ago?

Now why does that number ring a doom bell with me?

Re: Giant 'balloon of magma' inflates under Santorini
The Nisyros volcano, part of the same chain as Santorini, is experiencing outgassing from some of its vents in the crater. Whilst this is nothing new, it hasn't occurred for some time.

The original caldera for Nisyros covers the sea floor between Nisyros & Kos islands - one big mother.

Thanks for this.

The volcanic islands of Kos & Nisyros

The Island of Kos is part of one of the biggest volcano calderas in Europe. There was a explosion of the Kos volcano many times larger than the one that happened at Santorini in Minoan times. 140.000 years ago the south-western part of Kos was blown in the air by a huge eruption. Even today you can find thick layers of pumice and pyroclastic rocks on the island. The western part of Kos, the Kefalos peninsula is dominated by huge volcano domes. The islands of Strongyle, Yali and Nisyros are the today active centers of this volcano caldera. Nisyros is a small circular volcanic island around 30 km south of the island of Kos.
It is one of the most interesting active volcanoes of Greece.

Re: Giant 'balloon of magma' inflates under Santorini
Nisyros (Greek: Νίσυρος) is a volcanic Greek island and municipality located in the Aegean Sea. It is part of the Dodecanese group of islands, situated between the islands of Kos and Tilos. Its shape is approximately round, with a diameter of about 8 km (5 mi), and an area of 41.6 km2 (16.062 sq mi).[4] Several other islets are found in the direct vicinity of Nisyros, the largest of which is Gyali. The Municipality of Nisyros includes Gyalí (pop. 21) as well as uninhabited Pacheiá, Pergoússa, Kandelioússa, Ágios Antónios, and Stroggýli. It has a total land area of 50.055 km2 (19.326 sq mi) and a total population of 1,008 inhabitants. The island was also called Nisiro (in Italian) and İncirli (in Turkish).

Re: Giant 'balloon of magma' inflates under Santorini
Thanks OP.

There are areas near the village of Kefalos on Kos where there are fields of sulphur. You can see and smell it bubbling out from the ground most of the time. Also on the south coast, there is a beach where you can see gasses bubbling out into the water. These are a good 30+ km from the present crater for the volcano on Nisyros.

3,600 years is the cycle Hercolubus comes back around here according to Carlos Ferrada. He said it would cause great earthquakes and volcanoes. Isn't that also the number of the Sumerians cycle?



[link to www.livescience.com]
"No actual volcanic eruption has occurred in the Yellowstone National Park region of Wyoming, Montana, and Idaho since a lava flow poured out about 70,000 years ago. In the 1970s, a resurvey of benchmarks discovered the unprecedented uplift of the Yellowstone Caldera of more than 28 inches (72 cm) over five decades. These new data reveal that Yellowstone is in nearly continuous but frequently changing movement—the floor of the caldera continued to rise until 1984, stopped rising during 1984–85, and then subsided for the next 10 years."
[link to pubs.usgs.gov]
"At Yellowstone, scientists measured over two feet of uplift during the period 1923-1985, followed by a shorter period of subsidence."

And now?

Yellowstone Super Volcano Roaring To Life, Professor Bob Smith Says Nothing Like This In The 53 Years He Has Watched it
"Right now, the ground underneath Yellowstone National Park is rising at a record rate. In fact, it is rising at the rate of about three inches per year. In September, 130 earthquakes hit Yellowstone over the course of a single week. This has got many Yellowstone observers extremely concerned…"
#4 There are approximately 3,000 earthquakes in the Yellowstone area every single year.
#9 The “volcanic winter” that a massive Yellowstone eruption would cause would radically cool the planet. Some scientists believe that global temperatures would decline by up to 20 degrees.

Scary stuff there! Sorry OP, looked to see if it was doing anything and it is >.> Doing the same thing, swelling upwards so I pasted some of it.
