Nashik: In response to a series of 45 low-intensity tremors recorded across Nashik district over the past fortnight, the district administration has ordered a comprehensive survey of all buildings marked ‘red’ as unsafe for habitation, along with structures that have developed cracks, to assess whether they remain fit for occupation.The tremors, ranging from 2.6 to 4.1 on the Richter scale, have rattled several parts of the district and caused anxiety among residents. While experts from the Geological Survey of India (GSI) and the National Centre for Seismology (NCS) have ruled out the possibility of major damage from the tremors, officials have decided to take preventive measures.Collector Ayush Prasad said the administration was closely monitoring the situation and would act swiftly wherever public safety was at risk. “These tremors, at the most, lead to cracks in the walls. However, rainwater seepage can make the damage worse, especially in buildings already marked as ‘red’ and unsafe for habitation. We have ordered a fresh inspection of such structures and asked local civic bodies to prepare evacuation plans wherever required,” said Prasad.According to the administration, six cases from Surgana, Peth, Dindori and Kalwan talukas have been flagged for immediate follow-up to determine whether the damage is serious enough to warrant intervention.Resident deputy collector Rohit Rajput said assistance proposals would be prepared after assessing the damage.“Following the panchanama of these affected buildings, proposals that meet the requirements of the National Disaster Management Authority and State Disaster Management Authority will be prepared and sent for granting of help.”Authorities are also preparing contingency plans to relocate residents to community halls, wedding halls and schools if evacuation becomes necessary.Explaining the geological factors behind the cracks, Prasad said tremors often affect shallow soil layers above basalt rock formations, where heavy monsoon rainfall can trigger underground water movement and increase the risk of landslides.“We have identified 25 villages in Trimbakeshwar taluka that are affected because of such movements and are preparing for the relocation of the people on temporary basis. Also measures to treat the problems are being worked out,” the collector added.The administration has urged residents to report fresh cracks or structural damage immediately while maintaining that the tremors recorded so far are of low intensity and not expected to cause large-scale destruction.
