Inu is a lakeside village along the Lake Kutubu.
Baiyo Baboro, a local there, said the earthquake rattled their area at around 3am on Monday morning, splitting the ground. The lake water and river Mubi rose up, covering parts of the village.
Also submerged now is the Inu Primary School, Inu Sub-health Centre and the secondary school.
Villagers, students, teachers and other public servants in the area are cut off, stranded on this island.
Baboro said the tremors are still being felt and water is rising.
