    The shock of the earthquake in Pakistan has brought another shock: the rise of a mysterious island, coming out from the water.

In the aftershock of the earthquake, people living in Grabian Sea and saw a mountain-like shape coming out of the water. “It looked like a huge whale,” Bahram Baloch, a local reporter, told the BBC. “Lots of people gathered to watch it. ”

So what happened? The force of the earthquake was so strong that it moved the sea floor, releasing gas(释放气体). This gas pushed the seabed, mostly rock and sand, out of the water.  This was how the mud volcano (泥火山) was formed. The island which is about 20 meters high, 30 meters long and 90 meters wide is actually the top of the mud volcano.

Is it safe? Although people have visited this new island, scientists have found dangerous gas coming from the newly formed island. “It will catch fire, when a match was lit,” said Mohammad Danish, a scientist, to Universe Today.

The mud volcano is strange because mud volcanoes seldom appeared in an area where people often live, and not far out in the sea. It is a special one. However, it’s not expected to last very long. Most of these mud volcanoes are swept back under the sea within one year.
