Fresh Geological Investigation: Subsidence Threatens Joshimath Town
Joshimath, a town in the Chamoli district of Uttarakhand, is currently facing the threat of subsidence. To address this issue, experts from the Geological Survey of India (GSI) and the Landslide Mitigation and Management Centre (LMMC) are conducting a fresh geological investigation. The aim is to map the area and track rainwater percolation, which is believed to be a contributing factor to the subsidence.
The need for this investigation arose after cracks were observed on a section of the Auli road, which were subsequently repaired. Additionally, land subsidence was reported on a walking path in the Singdhar municipal ward. Concerned about the situation, the district magistrate of Chamoli, Himanshu Khurana, wrote to the state government, requesting a fresh geological investigation to determine the cause of the problem.
Ranjit Sinha, secretary of the disaster management department, explained that the GSI has been assigned the task of conducting geological and topographic mapping of Joshimath. This mapping will provide crucial information about the affected areas and help in planning effective measures for disaster mitigation. Notably, a geological map of 1:5000 scale is being prepared for the first time, which will greatly contribute to future planning.
The LMMC team is focusing on tracking rainwater patterns and identifying natural drains in the area. These drains play a significant role in the subsidence as water seeps or passes through the town on a slope. Understanding this process is crucial to developing appropriate mitigation strategies.
The subsidence issue in Joshimath became more severe in the first week of January, resulting in the displacement of approximately 1,000 families. A total of 868 houses developed cracks, with 181 declared unsafe for habitation. In response, the state government requested a study from eight central scientific and technical institutions to investigate the causes of subsidence and propose solutions. However, the findings of this study are yet to be made public.
The ongoing fresh geological investigation is a significant step towards addressing the subsidence threat in Joshimath. By analyzing the geological and topographic characteristics of the area and studying rainwater percolation, experts hope to gain a better understanding of the causes of subsidence. This knowledge will be vital in planning and implementing mitigation measures to prevent further damage and safeguard the lives and properties of the residents.
It is crucial to approach this issue with a balanced view, considering various perspectives and opinions. By prioritizing the well-being of the affected population and the need for sustainable solutions, the authorities can ensure the long-term stability and safety of Joshimath town.
