Meantime, the State government distributed plastic tarpaulins to various ashramshalas (government hostels for tribal students) in the Dahanu and Talasai areas, as students of tribal schools are studying in the open due to the mild tremors. The tarpaulins are to cover bamboo
temporary sheds and converted into a makeshift school, and also provided the boarders bedsheets,blankets and pillows to them so that they could stay inside the temporary sheds as we also provide food including breakfast and lunch daily but the students prefer to go to their homes instead after school he said and not stay with us due to the tremor fear he said.
Fear among the residents are also on the rise said Anand Thakur,MLC of the area. The tribal residents are staying in the open and spend the chilly nights near their homes so if they stay away there are chances of theft of property said Thakur. We have asked for special funds for the construction of temporary sheds for the tribals so that they could shift inside them, due to their fear of the mild tremors, said a government official.
However, people of the above two areas are not taking any chances,and since the past weeks are spending the nights in the open air, braving the chilly winds,due to the winter season.
