Zalzala Koh (Urdu: زلزلہ جزیرہ, Earthquake Mountain) or Zalzala Jazeera (Earthquake Island) was a small island off the coast of the port city of Gwadar in Balochistan province of Pakistan which appeared on 24 September 2013 following an earthquake. As predicted by many geologists, the island soon started to submerge, with satellite images indicating the island had sunk 3 m (10 ft) into the sea one month after its initial appearance.[2] By the end of 2016, the island had disappeared.[3]

Formation


Zalzala Koh may have been be a mud volcano,[4] located in the Arabian Sea offshore of Gwadar in Balochistan, Pakistan. It rose out of the water during a 7.7-magnitude earthquake that struck the same province on 24 September 2013.

Ali Rashid Tabriz, the head of Pakistan's National Institute of Oceanography, said that the surfacing of the island had been caused by an emission of methane gas on the seabed.


Location


The island was visible from Pakistan's coastline[5] and was about 2 kilometres (1.2 mi) from the shore, with a height of 15 to 20 metres (50 to 65 ft), a length of 175.7 m (576 ft), width of 160.9 m (528 ft), and a surface of 22.726 m2 (244.62 sq ft) (measured from satellite Pleiades). These figures were debated, though.[1][6][7][8]


Ecology


While the surface was lifeless, the seas around the island became a haven for fish and other life forms (including the coral Acabaria delicata), which boosted the local fishing industry.[9]
