When a magnitude 7.8 earthquake struck Pakistan’s Baluchistan province on Tuesday, locals watched in amazement as a small island rose out of the sea 600 metres off the coast.
Scientists have been studying data from the quake and fielding questions about what caused the island to appear.
They have since said that the island is actually a mud volcano, caused by pressure in sediment below the seabed.
