Flood is a complex outcome of an interface between geological, physiographical, hydrological, meteorological and anthropogenic dynamics. It mandates high computational techniques for the analysis of a large volume of hierarchical pictorial data. GIS technology, inseparably interleaved with remote sensing, helps to panoramically beam complex issues involving river floods and the feasibility of detecting and mitigating them.
Kerala has witnessed one of the most devastating floods in history. Many lives and livelihoods were lost in just a few days. To reduce future occurrences and the impact of such calamities, it is important that we focus on implementing and improving the measures that can offer greater resilience.
Given India’s population, its density, concentration in particular geographies and weak state of its institutions of governance, adopting precautionary measures to disaster preparedness becomes imperative. These measures should have roots in deep, systemic scientific analysis based on flexible, responsive governance structures.
Why landslide mitigation is important The monsoons may bring life and prosperity to our agrarian societies, but it also has harmful consequences, especially for hilly regions. The monsoons have already begun to wreak havoc this year with persistent heavy rains leading to floods and landslides in many parts of Northeastern India that have claimed more than 80 lives according to government officials in the month of July 2017 (Indian Express, 2017), along with large numbers of people displaced by floods...
Natural phenomena are largely benevolent and are beneficial to society. However, at times these are of severe intensity and thus become hazardous. When societies fail to cope with hazards they turn into disasters. It is ironical that on one hand improved hazard monitoring, early warning system and disaster management practices have helped in mitigating adverse impact of hazards; on the other hand land use changes have turned hazards in to disasters. It is interesting to note that land use change...
Earthquake is one of the most destructive natural disasters. Learn how to keep yourself safe in case you ever encounter a devastating earthquake event. Earthquake safety tips would really saves lives and prepare us for such destructive natural disaster.
There has been a paradigm shift in cyclone warning services in India due to the modernisation programme and other initiatives taken by the Ministry of Earth Sciences.
India has made some major advances in seismological research in the past few decades. However, gaps continue to remain, and populations remain vulnerable to earthquakes and tsunamis. Initiatives like microzonation, and scientific drilling may yet provide a solution to these problems.
Extreme rain and cities of the world A study at the University of New South Wales, Australia have determined that cities face harsher and more concentrated rainfall as climate change not only intensifies storms, but draws them into narrower bands of more intense downpours. The findings have major implications for existing storm water infrastructure, particularly in large cities, which face higher risks of flash flooding. https://www.geographyandyou.com/climate-change/environment/extreme-weather-events/ The...
More than a decade after the 2004 Andaman-Sumatra earthquake/tsunami, offshore and deep ocean observation systems now contribute to early tsunami warning efforts in India. The lessons we learnt from this catastrophe taught us to develop better strategies for disaster-preparedness.
