Tsunami Early Warning System in India

 


Why in News

According to experts from the Indian National Centre for Ocean Information System (INCOIS), India is much safer against tsunami threats than it was in 2004, due to the establishment of a state-of-the-art tsunami early warning system at INCOIS.

Key Points

  • Indian Tsunami Early Warning System:
    • The Indian Tsunami Early Warning System (ITEWS) was established in 2007 and is based at & operated by INCOIS, Hyderabad.
    • It is an integrated effort of different organizations including the Department of Space (DOS), Department of Science and Technology (DST), the Council of Scientific and Industrial Research (CSIR), Survey of India (SOI) and National Institute of Ocean Technology (NIOT).
    • ITEWS comprises a real-time network of seismic stations, tide gauges and a 24X7 operational tsunami warning centre to detect tsunamigenic earthquakes, to monitor tsunamis and to provide timely advisories to vulnerable communities.
    • Indian scientists can detect large undersea earthquakes in the Indian Ocean in real-time and provide a tsunami warning in 10-20 minutes after the earthquake occurs.
      • In 2004, India didn’t have any tsunami warning capability nor any public knowledge of tsunamis in the Indian Ocean.
    • India is among the first few centres to introduce quantitative tsunami forecasts.
      • Intergovernmental Oceanographic Commission (IOC) of UNESCO (also known as UNESCO-IOC) accredited Indian Tsunami Early Warning Centre (ITEWC) as Tsunami Service Provider (TSP) for 28 Indian Ocean Rim (IOR) countries, along with Indonesia and Australia in 2011, for issuing regional warnings.
  • Recent Focus in Tsunami Warning Capability:
    • The focus in recent times has been on enhancing community awareness and response through several capacity-building activities, biennial Indian Ocean wide tsunami drills and piloting of the UNESCO-IOC Tsunami Ready initiative.
      • Tsunami Ready is a community performance-based programme to promote tsunami preparedness through the active collaboration of public, community leaders, and national and local emergency management agencies.
      • The main objective of this programme is to improve coastal community's preparedness for tsunami emergencies, to minimize the loss of life and property and to ensure a structural and systematic approach in building community preparedness through fulfilling the best-practice indicators.
      • Two villages of Odisha- Venkatraipur in Ganjam district and Noliasahi in Jagatsinghpur district are now ‘Tsunami Ready’.
    • INCOIS is establishing a network of 35 stations to estimate the tectonic plate’s movements in real-time and measure the vertical displacements under the sea directly.

World Polio Day 2020

  World Polio Day  (October 24) provides an opportunity to highlight global efforts toward a polio-free world and honor the tireless contributions of those on the frontlines in the fight to eradicate polio from every corner of the globe. Through the Global Polio Eradication Initiative (GPEI), CDC works with partners to eradicate polio and end the suffering from this devastating disease. Stopping polio in all forms will require us to be resilient, adapt, and innovate to deliver a polio-free world. Resiliency and Innovation in the Face of Challenges This year the polio program has marked inspiring and important milestones, developments, and challenges for advancing progress toward polio eradication, including: Certification of the African Region as wild poliovirus-free in August Testing and preparation for the introduction of novel oral poliovirus type 2 vaccine (nOPV2), a new tool to stop outbreaks of circulating vaccine-derived poliovirus type 2 (cVDPV2). Supporting many count...

Aquaponics Facility

  Why in News A  pilot ‘Aquaponics facility’  has been developed by the   Centre for Development of Advanced Computing  (C-DAC) , Mohali at Guru Angad Dev Veterinary University (GADVASU), Ludhiana. Key Points State-of-the-art facility:  It is equipped with  advanced sensors  for  monitoring and automated controls  of the farming system. The  supercomputing power being provided by C-DAC  in developing agriculture technology. Funding Support  was provided by  the Ministry of Electronics and Information Technology  (Meity). Other Features: The facility is  nearly 100% organic. Needs much less land for a given yield of crop. Consumes 90% less water. The fish and plants grown together are more nutritious. Significance: Demand  for fishes and crops (lettuce, spinach, capsicum, coriander, broccoli and some other leafy plants) is increasing rapidly in urban areas. The  aspirational rural youth will be draw...
