Tidal waves that began battering the coastal areas of Valiathura and Cheriyathura earlier this week have prompted the authorities to open two relief camps on Wednesday.

As on Wednesday, 106 families, whose houses were inundated on Tuesday, had been shifted to the two camps set up at the Valiathura Government Fisheries School and the Government UP School there, B. Sashikumar, tahsildar, Thiruvananthapuram, said.

Four houses in the Thiruvallam village were also inundated, but the families had shifted to the houses of relatives.

District Collector Biju Prabhakar, who discussed the situation with officials on Wednesday, said all arrangements, including for food, were made and that the district administration was monitoring the situation.

The Collector would visit the affected areas on Thursday. Health Minister V.S. Sivakumar visited some of the areas on Wednesday.

Valiathura councillor Tony Oliver, meanwhile, said the situation could have been avoided had the several projects, including those for rehabilitation of people in the area, were not delayed.
