It has absolutely nothing to do with Greece. But I find this news really awesome! That a new island emerged from the sea after an earthquake.
Below a BBC story on the island that emerged off shore of Pakistan!
Footage shows people flocking to see the new island, which oceanographer Dr Simon Boxhall describes as “quite extraordinary, but not unique”
Barely half an hour after they were jolted by a major earthquake on Tuesday, people of the Pakistani coastal town of Gwadar had another shock when they saw a new island emerge in the sea, just over a kilometre from the shore.
A local journalist, Bahram Baloch, received the news via a text message from a friend.
“It said a hill has appeared outside my house,” Mr Baloch said.
“I stepped out, and was flabbergasted. I could see this grey, dome-shaped body in the distance, like a giant whale swimming near the surface. Hundreds of people had gathered to watch it in disbelief.”
Local witness: “We could hear the hissing sound of the escaping gas” said Bahram Baloch local journalist.
“It’s an oval shaped island which is about 250ft to 300ft (76-91m) in length, and about 60 to 70ft above the water,” he said
It has a rough surface, much of which is muddy and some parts are mostly made up of fine- to coarse-grained sand. One part of it is solid rock, and that is where Mr Baloch and his friends landed.
“There were dead fish on the surface. And on one side we could hear the hissing sound of the escaping gas,” Mr Baloch said.
Though they couldn’t smell methane, they did put a match to the fissures from where the gas was oozing, and set it on fire.
“We put the fire out in the end, but it was quite a hassle. Not even the water could kill it, unless one poured buckets over it.”
The story now doing the rounds in Gwadar is that a similar hill had jutted out of the sea 60 or 70 years ago, and that the elders had then named it the Zalzala Koh, or the quake hill.
They say Tuesday’s earthquake has brought it back.
Their story is not entirely incorrect. However the quake hill that appeared in 1945 was not near Gwadar, but over 100km to the east, although it was along the same coastline, which is called the Makran coast.
About 700km from east to west, the Makran coast is characterised by high seismic activity, and is home to several hills called mud volcanoes, having craters at the top from which methane gas seeps.
These volcanoes are located inland, and have been there for a long time. But similar formations that emerge offshore are usually washed away by the sea.
Geologists say it is part of the continuing process of continental drift, or the drift of land mass across the oceans that brought the Indian sub-continent to collide with Eurasia and created the fault-lines, some of which run through the Makran coast.
“The island that popped up is the fourth in this region since 1945”

Rashid Tabrez, the director-general of the Karachi-based National Institute of Oceanography, says the energy released by the seismic movements of these fault-lines activates inflammable gases in the seabed.
“The seabed near the Makran coast has vast deposits of gas hydrates, or frozen gas having a large methane content,” he explained.
“These deposits lay compressed under a sediment bed that is 300m-800m thick.”
“When the plates along the fault-lines move, they create heat and the expanding gas blasts through the fissures in the earth’s crust, propelling the entire sea floor to the surface.”
The island that popped up near Gwadar is the fourth in this region since 1945, and the third during the last 15 years, he said. (full article and more pictures BBC)
