Tsunamis: Cause and everything else you need to know
Tsunamis are one of the most devastating natural disasters on Earth, often arriving without warning and causing widespread destruction. A tsunami is a series of powerful ocean waves usually triggered by undersea earthquakes, volcanic eruptions, or landslides. These waves can travel at speeds of up to 800 km/h and grow in height as they approach coastlines, making tsunami awareness and early warning systems critical for saving lives. In this guide, we'll explain everything you need to know about tsunamis, their causes, effects, detection, and safety tips, while exploring why tsunami preparedness is more important than ever in today's changing a comprehensive guide that covers everything you need to know about tsunamis, from their origin to the latest technologies used for detection and IS A TSUNAMI?A tsunami is a series of ocean waves caused by large, sudden displacements of water, typically resulting from:Undersea earthquakesVolcanic eruptionsLandslidesOr, in rare cases, meteorite impactsUnlike ordinary waves formed by wind, tsunamis carry massive energy, often traversing entire ocean basins at jetliner AND TERMINOLOGYThe word tsunami is derived from Japanese: tsu (harbor) and nami (wave) a nod to the devastating effects these waves have had on Japanese coasts over they were also called 'tidal waves,' but that term is misleading since tsunamis have nothing to do with OF TSUNAMIS1. Subduction zone earthquakes (Most common cause)When tectonic plates collide and one plate slips beneath another (a process called subduction), immense energy is released. If the sea floor is displaced vertically, water is shoved upwards or downwards, creating waves that radiate outward.2. Volcanic activityUnderwater eruptions or collapsing volcanic islands can rapidly displace water.3. Landslides and glacial calvingLarge chunks of rock or ice plunging into the sea displace water instantly.4. MeteoritesRare but catastrophic, an asteroid impact in the ocean could generate massive tsunamis. Though unlikely, this is the basis of many global extinction theories. Tsunamis: What causes them and everything else you need to know HOW ARE TSUNAMIS DETECTED?Tsunami Early Warning Systems (TEWS) have been set up in vulnerable regions. Key components include:Seismic Monitoring: Detects undersea Buoys: Deep-ocean Assessment and Reporting of Tsunamis use pressure sensors to detect water column Gauges: Measure sea level rise at Monitor and relay real-time Alert Systems: Sirens, mobile alerts, and radio India, the Indian National Centre for Ocean Information Services (INCOIS) operates a state-of-the-art tsunami warning centre in FORECASTING AND MODELLINGOnce a potential tsunami is detected:1. Location and depth of the seismic event are analysed.2. Models simulate how waves will propagate.3. Coastal communities receive warnings and evacuation tsunamis cannot be predicted in advance. Scientists can only issue alerts after a triggering event has TO DO DURING A TSUNAMI?BeforeKnow your evacuation up for local an emergency to higher ground away from beaches and wait for official warnings if you feel a strong earthquake near the coast, natural warning signs include:EarthquakesUnusual sea withdrawalRoaring ocean soundAfterStay tuned to official debris-laden others if you can, and follow rescue team AFFECTED REGIONSTsunamis are most frequent around the Pacific Ocean's 'Ring of Fire,' a seismically active zone. However, other regions including the Indian Ocean, Mediterranean, and parts of the Atlantic are also HISTORIC TSUNAMIS2004 Indian Ocean – Over 230,000 lives lost2011 Japan (Tohoku) – Triggered a nuclear disaster at FukushimaARE TSUNAMIS GETTING MORE DANGEROUS?With climate change and rising sea levels, coastal vulnerabilities are increasing.

We are equipping youth with future skills: Lokesh
Singapore: Minister for education, IT, and electronics Nara Lokesh on Monday declared that the state is actively preparing its youth with future-ready skills, moving beyond traditional education to meet the demands of a rapidly evolving technological landscape. He stressed that the challenges of workforce transformation are not limited to any single region, and Andhra Pradesh aims to collaborate with Singapore for accelerated transformation. Speaking at a round-table conference on 'Skills to Competencies, Accelerating Workforce Transformation' in Singapore, Lokesh said, 'In today's competitive world, with technology advancing at a rapid pace, traditional education is no longer sufficient for skill development. The Fourth Industrial Revolution demands not just technical skills but also competencies.' He highlighted the need for individuals to possess the ability to adapt, innovate, and solve complex problems in dynamic environments. 'As the IT & electronics minister of Andhra Pradesh, we are striving to position our state as a hub for innovation and a leader in workforce transformation,' he said. 'We are not just preparing our youth for jobs; we are equipping them with the skills necessary for the future.' He announced that Andhra Pradesh universities are introducing skill development courses and fundamentally changing curricula to align with international technological advancements. 'We are ready to work with Singaporean universities on research, innovation, student exchange, and entrepreneurship,' Lokesh added. He stressed the need for Andhra Pradesh and the organisations represented in Singapore to collaborate to create synergies that accelerate transformation. R. Rajaram (registrar, National University of Singapore), Sia Siew Kien (associate vice president, Nanyang Technology University), Professor Pradeep Reddy (Singapore Management University), chairman Professor Rajesh Elara Mohan (Singapore University of Technology and Design), associate professor Yap Meen Sheng (Singapore University of Social Science), and Chen Hong Xiang (business development director, Skills Future SG Ventures) attended the conference.

Singapore researchers develop AI-based model to predict liver cancer recurrence
Singapore, July 21 (UNI) Singaporean researchers have developed an artificial intelligence-powered scoring system capable of predicting the recurrence of liver cancer, according to a press release from the Agency for Science, Technology and Research on Monday. Developed by scientists from the Institute of Molecular and Cell Biology (IMCB) under the agency in collaboration with the Singapore General Hospital, the system can forecast the recurrence of hepatocellular carcinoma, the most common type of liver cancer, with approximately 82 per cent accuracy. The system works by analyzing the spatial distribution of natural killer immune cells and five key genes within liver tumor tissues. "In Singapore, up to 70 per cent of liver cancer patients experience recurrence within five years," said Principal Investigator Joe Yeong from the IMCB, noting that this system empowers clinicians to intervene as early as possible. Researchers validated the system using tissue samples from 231 patients across five hospitals. It is now accessible via a free web portal for research purposes, with plans underway to integrate it into standard clinical workflows. Further validation studies are scheduled to begin later this year. UNI XINHUA AKT PRS
