ギリシャに災難、サントリーニ島火山が70年ぶりの噴火リスク http://www.bloomberg.co.jp/news/123-MA4J9U6TTDT901.html
９月10日（ブルームバーグ）：エーゲ海クルーズの寄港地として人気の高いギリシャのサントリーニ島で、3600年前の噴火でクレタ島を中心に栄えていたミノア文明を壊滅させた火山が70年ぶりに噴火する可能性が出ている。
英オックスフォード大学を中心として研究者らがネイチャー・ジオサイエンス誌に発表したところによると、サントリーニ火山の地下マグマの量が2011年１月－12年４月までの間に1000万－2000万立方メートル増えた。増えた量は最大で、ロンドン五輪会場の15倍だという。
論文の筆者らは、マグマのデータが差し迫った噴火を示唆するものではないが、その可能性を排除することはできないとしている。火山の調査結果は現在の活動状況が「1939－41年の噴火とその直後以降で唯一の意味のあるものだということを強く示唆している」という。

'Atlantis'-killer volcano under island of Santorini wakes again http://www.heraldsun.com.au/travel/news/atlantis-killer-volcano-under-island-of-santorini-wakes-again/story-fn32891l-1226471552512
IT destroyed the Minoan civilisation and sent shockwaves through history as the legend of Atlantis. Now, the volcano of Santorini is stirring again.
Almost four thousand years ago, the island of Santorini was probably much as it is now - a scenic retreat for the Minoan's wealthy and powerful.
And history may be set to repeat itself: Magma has been detected once again pouring up to 20 million cubic metres of molten rock into chambers deep beneath the idyllic island.
A report in the scientific journal Nature Geoscience says the island has lifted as much as 14 centimetres in recent years. And seismic sensors placed around the island earlier this year registered a string of small earthquakes - the first after 25 years of dormancy.
From the hints and clues unearthed in the buried town of Akrotiri, the island was an important and extravagant trading hub - with remarkable similarities to the mythical civilisation of Atlantis.
One ancient wall map clearly shows a palace built upon a small island embraced by another ring-like island. Roman historian Plato said Atlantis was an island of concentric rings.
What the ancients didn't know was that the mound they had built upon was the peak of a volcano, nosing out of the water-filled caldera of an even more ancient volcano.
One of the most violent volcanic eruptions in recorded history blasted much of the island into the ocean - vaporising the central palace and burying settlements under metres of volcanic ash.
The resulting 12 metre tsunami devastated the Minoan coastal cities on nearby Crete. It was a disaster the civilisation never recovered from.
Knowing Santorini is a volcano has not stopped the island from once again being turned into an island resort. It is a regular stop-over for cruise liners and Greek-island holidaymakers.
"Although Santorini is well known for its large explosive eruptions, these probably only happen every 20,000 years or so," Oxford University researcher David Pyl said.
Smaller, more frequent dome-forming eruptions can happen as frequently as every 14 years.
The volcano had its last significant eruption about 70 years ago.
"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.
