The island, located south of the Hariabhanga river, has been claimed by both Bangladesh and India for almost thirty years, since it first appeared in the seventies as a mud flat created by variable currents in the river delta . The School of Oceanographic Studies in Calcutta commented that the disappearance of the island was confirmed by satellite imagery. Hazra claimed that, until 2000, sea levels in the area increased approximately three millimetres annually, but in the past year the figure was augmented to about five millimetres. The director said that ten other islands in the vicinity of New Moore were in danger of being submerged as well. An average of three millimetres per year over 30 years would be 9cm. According to officials, eighteen percent of the Bangladeshi coastal land will be submerged if sea levels increase by one metre by 2050, and twenty million people will be displaced . However the US National Oceanic and Atmospheric Administration's nearest tide gauge at Vishakhapatnam, India, (which has measured sea levels since 1937) shows a mean sea level rise of 0.54mm (+/-0.52) mm/yr - an indicated rise of approximately 1.5cm in 30 years .
