In an unusual occurrence, the sea receded up to 50 metres to 100 metres at the Kothi Beach near Nainamvalappu in Kozhikode on Saturday evening.
However, the Kerala State Disaster Management Authority ruled out the possibility of a Tsunami as the withdrawal of sea is normally treated as a natural warning.
According to the locals, the phenomenon started by 4 pm and the sea had receded almost 50 metres across about 200 metres of shoreline.
