India plans smart tsunami and earthquake early warning system with underwater sensors
India is laying the groundwork for a smart tsunami and earthquake early warning system with a 275 km-long underwater cable in the Indian Ocean. The system could change the way seismic activity, submarine landslides, and other deep-ocean threats are detected. The initiative, still at the Request for Proposal (RFP) stage, is conducted by the Indian National Centre for Ocean Information Services (Incois), Hyderabad. It aims to overcome limitations in the existing system that relies primarily on surface buoys. The communication cable equipped with sensors will be laid at a depth of about 2,500 m in the Indian Ocean from the Andaman Islands to the seismically active Andaman-Nicobar subduction zone. This cable will host a suite of sensors, including bottom pressure recorders, seismometers, tilt meters, and hydrophones, enabling real-time monitoring of seismic activity, undersea landslides, and sudden pressure changes. It will help gather long-term observations of the Indian Ocean and study oceanographic and geophysical parameters for climate research and operational applications also related to storm surge early warning systems. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 2025 Top Trending local enterprise accounting software [Click Here] Esseps Learn More Undo "The region is monitored with tsunami buoys that have a bottom pressure recorder and a surface buoy," says T M Balakrishnan Nair, Director of Incois. "Though data is transmitted to the Indian Tsunami Early Warning Centre in Incois, maintaining the buoys is challenging as they are vulnerable to environmental conditions." He adds that the system will be reliable and provide high-bandwidth data related to seismic activity directly to shore stations. The Andaman-Nicobar subduction zone is where tectonically active Indian plates subduct beneath the Eurasian plate. This process is responsible for the formation of the Andaman and Nicobar Islands and has historically been a hotspot for seismic activity. The entire northwestern segment ruptured during the 2004 Andaman-Sumatra earthquake, which led to the tsunami. The plan also includes setting up a dedicated shore station in the Andaman Islands, which may eventually evolve into a regional tsunami service centre, given the islands' vulnerability to tsunamis. The cable will be connected to the data processing centre in Hyderabad to ensure rapid dissemination of alerts. Email your feedback with your name and address to

Toxic cargo poses threat to marine life
1 2 3 Kozhikode: The marine life and ecology in the Arabian Sea off the Kerala coast face serious threat if the hazardous chemicals aboard the Singapore-flagged vessel MV Wan Hai 503, which is on fire, were to leak into the sea, especially during the ongoing fish breeding season. The vessel is now 44 nautical miles off Azhikkal coast. The ship is carrying tonnes of highly dangerous substances, including 16 officially classified marine pollutants and dozens of other toxic chemicals. Some of them are known carcinogens which can have long-term impact on marine ecology as well as human health. The Central Marine Fisheries Research Institute (CMFRI ) has started collecting seawater samples to check for chemical presence. The chemicals which have chronic marine toxicity in the cargo manifest include trichlorobenzene which affects aquatic life, hydroquinone which also has mutagenic potential and tetrachloroethylene which is a probable carcinogen among many others. CMFRI Kozhikode regional station head Anulekshmi Chellappan said the hazardous and toxic chemicals, as per the list shared, if leaked to the sea, may negatively affect the marine life, especially since it is the fish breeding season. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Top 5 Dividend Stocks for May 2025 Seeking Alpha Read Now Undo However, the extent of the impact can only be determined after a detailed scientific study and understanding of the spilled items and their magnitude. "We've already started collecting and testing water samples and sediments from coastal waters of Kannur, Kozhikode and Malappuram districts. Fish samples are also being taken from traditional vessels. Based on prevailing southern and southeastern currents and advisories from Incois, the effects are likely to be felt most significantly in the districts from Kozhikode to Kochi," she said. She said of the 157 listed substances aboard the vessel, at least 43 are classified as marine pollutants. "Pollutants from ship could still harm marine ecosystems," she said. "We have initiated a study and monitoring to estimate how much of the ship spills, hazardous substances listed in the cargo manifest would impact marine organisms," she said. Anulekshmi added that the small-scale fisheries are operating close to shore far away from accident area and this is a ban period for mechanised fishing operated mostly in offshore waters. Kufos aquatic environment department head Anu Gopinath said the incident involving MV Wan Hai would pose a more serious threat to marine life and ecology when compared to the recent sinking of MSC ELSA 3 off Kochi coast. "What is of concern is the huge quantity of hazardous substances in the cargo. There are category 6 pesticides and many other toxic substances. If they reach the sea, then the damage could be huge. It might not manifest in the next few days or weeks, and we have to look at the effect of the chemicals on the Kerala coast and marine environment in the long term. We need to do comprehensive long-term monitoring to see the extent of the spread and see if the marine life is having a concentration of the chemicals," she said. Gopinath added that apart from fish which has some ability to evade adverse conditions like these, other sedentary marine life forms and microorganisms would also be most affected.

IMD issues warning for thunderstorms in Kerala
Kochi: IMD issued a warning for thunderstorms in Kerala until Wednesday.A yellow alert was issued for Pathanamthitta, Idukki, and Malappuram on Tuesday, while Ernakulam, Malappuram, Wayanad, and Kannur were on alert for Wednesday. Thunderstorms accompanied by lightning and gusty winds with speeds reaching 40-50 kmph are very likely to occur at one or two places over Kerala until was reported that the trough from Saurashtra to the east-central Arabian Sea across the northeast Arabian Sea persists. An upper air cyclonic circulation is likely over the southeast Bay of Bengal adjoining the south Andaman Sea until Wednesday. The north-south trough from Marathwada to Gulf of Mannar across interior Karnataka and Tamil Nadu became less are favourable for the advance of the southwest monsoon into some parts of the Andaman Sea, south Bay of Bengal, and Andaman and Nicobar Islands by Tuesday. It is also favourable for further advancement over some parts of the south Arabian Sea, Maldives, and Comorin area in the next four to five maximum temperatures were above normal in Kottayam, Palakkad, Kollam, Thiruvananthapuram, and Thrissur districts. Palakkad recorded the highest maximum temperature of 37.5 degrees National Centre for Ocean Information Services (Incois) issued a swell surge alert for the coastal regions of Alappuzha, Ernakulam, Kannur, Kasaragod, Kollam, Kozhikode, Malappuram, Thiruvananthapuram, and Thrissur. Swell waves in the range of 15-16 seconds period with 0.4-0.5m height are forecast until 11.30pm on Tuesday. It advised that there is a possibility of surging waves, and boats should ply with utmost vigilance, and recreation should be undertaken with due care.
