Pakistani officials are investigating a small island, about 60 feet high, 100 feet long and 250 feet wide, that has appeared off the coast of Pakistan following an earthquake which destroyed thousands of homes in Pakistan's remote Balochistan province.
Dr Brian Baptie, Head of Earthquake Seismology at the British Geological Survey said that the island was likely to be a mud volcano, created by the movement of gases locked in the earth under the sea, pushing mud and earth up to the surface.
"Mud volcanoes are often caused in certain areas as a result of ground shaking during earthquakes ... That shaking results in the release of mud and silt that is pressurised underground.
"They liquefy and can appear at the surface."
He said these types of islands can remain for a long time or eventually subside back into the ocean, depending on their composition.
Residents have been warned not to try to visit the island because it was still emitting gasses.
Such land masses have appeared before off Pakistan's coast. After quakes in 1999 and 2010, new land masses rose up along a different part of the coast about 175 miles east of Gwadar.
