100-Ft ‘Doomsday' Tsunami Could ‘Wipe Out' Part Of US ‘Any Moment'
The Cascadia Subduction Zone has stayed calm for 300 years. When it finally breaks, it could trigger a huge earthquake followed by a tsunami with waves as high as 100 feet.
While the world focuses on AI threats and the looming possibility of World War III, Mother Nature has issued a stark reminder of her own power. Scientists have long warned of impending natural disasters, and a new study published in the Proceedings of the National Academy of Sciences (PNAS) adds to those concerns.
The research suggests that the United States could soon face one of the most catastrophic natural disasters in its history.
What Is The Threat?
The Cascadia Subduction Zone has stayed calm for 300 years. When it finally breaks, it could trigger a huge earthquake followed by a tsunami with waves as high as 100 feet. The disaster could bring severe damage and threaten many lives from northern California in the US to British Columbia in Canada. According to a new study, this could cause sudden and serious changes.
Scientists found that during a major earthquake, the land could sink by 0.5 to 2 meters within minutes. Along with the sinking, rising sea levels could lead to a much bigger risk of flooding. The study warns that by the year 2100, the number of people, buildings and roads at risk of flooding could more than triple. Researchers say this growing danger needs more attention, planning, and action to reduce damage in the future.
What Scientists Are Warning The World About Now
'This is going to be a very catastrophic event for the US, for sure. It's a dual threat. The tsunami is going to come in, and it's going to be devastating. But with tsunamis, we also know that some places are going to be very hard hit, while other places are probably not going to feel as severe effects because of the way the coast is configured. But those areas can still be in the zone of subsidence," Dura added.
Rising Waters And Sinking Land
The study reveals that while many coastal areas are gradually sinking each year, parts of Washington, Oregon and Northern California are experiencing the opposite, land uplift due to deep underground movements. In cities like Astoria, Port Orford, and Crescent City, the land is rising faster than sea levels, causing water levels to remain stable or even decline slightly. However, in areas such as Yaquina Bay and Coos Bay, the land is rising more slowly, leading to a noticeable increase in sea levels.
One exception is Humboldt Bay in Northern California, where the land is sinking. Scientists warn that by around 2030, sea levels will rise faster than the land can keep up. By 2050, water levels may rise to 10 to 30 centimetres, and by 2100, sea levels might increase by 40 to 90 centimetres if carbon emissions stay high.

'It's His Rebirth': Tears & Prayers In Lucknow As Shubhanshu Shukla Makes Final Call From Space
Last Updated: Shukla's family said re-entry to Earth is the most dangerous part of the mission but the astronaut's confidence had given them the belief that all would end well 'This is my last call from the ISS…I'm coming back and will meet you all soon." With these parting words, Group Captain Shubhanshu Shukla, India's first astronaut aboard the International Space Station (ISS), signed off from Space in what his family calls the most emotional moment of his 18-day journey. The message came during a brief satellite call just hours before his scheduled undocking from the ISS at 4.30pm IST on Tuesday as part of the final leg of the Axiom Mission 4 (Ax-4). Though calm and composed, Shubhanshu's words hit hard back home in Lucknow. For the Shukla family, the upcoming return of their son is not just the end of a groundbreaking mission—but a moment akin to rebirth. 'The Call Was Different' 'This one was unlike all the earlier calls," recalled Suchi Shukla, his sister, speaking to News18. 'Usually, we speak freely, laugh, and ask him all kinds of questions. But this time, we all prepared ourselves to remain silent. The moment was heavy." His mother, Asha Shukla, broke down during the call. 'I couldn't speak. I just listened to his voice and cried. He knew I was crying, yet he stayed calm. He kept motivating us and saying everything would be fine," she said. 'That final call was emotional, but it gave us strength too." According to the family, everyone was fighting to hold back their emotions. 'We all knew it was the most critical phase of the mission—re-entry is dangerous. But deep down, we believe he will return safely. And the credit for that confidence goes to Shubhanshu," Suchi said. The family likens his return to a second birth. 'This mission feels like a rebirth of Shubhanshu," said Suchi. 'He went away from Earth into a completely different environment, and now he's returning with new experiences and memories. It's almost like he has come back from another world," she added. The family has been holding an 18-day special prayer session since the mission entered its final stretch, praying for the safe return of Shubhanshu and his fellow astronauts. 'The day he lands safely will not just mark the end of a mission—it will mark the end of our constant anxiety," Asha Shukla added. 'He is reborn for us." Call from Space that Brought Earthly Comfort Two days before the final call, the Shukla family also received a video call from the ISS that made the entire journey feel more real. 'He was floating in zero gravity, smiling, showing us around the space station," Suchi shared. 'For a few minutes, we forgot he was thousands of kilometres above us. It felt like he was just in the next room." Asha Shukla added, 'He looked healthy, his eyes sparkled. That video call took away so much fear. It made everything seem normal." Undocking Begins, Return Set for July 15 Group Captain Shukla, along with Commander Peggy Whitson, and Mission Specialists Sławosz Uznański-Wiśniewski and Tibor Kapu, began their return journey aboard SpaceX's Dragon spacecraft. The spacecraft undocked from the ISS on July 9 at 4:30 pm IST and is expected to splash down off the California coast on July 15, around 3:00 pm IST. Upon return, the crew will undergo a 10-day post-mission medical observation, as is standard for space travelers to ensure their physical adaptation after prolonged microgravity exposure. The Longest Indian Presence on ISS Originally planned for two weeks, the Axiom-4 mission was extended to nearly three weeks, making it the longest duration an Indian has ever spent on the ISS. Shubhanshu's inclusion on the Ax-4 mission was part of a landmark collaboration between ISRO and NASA, fulfilling a commitment made by Presidents Donald Trump and Joe Biden, and Prime Minister Narendra Modi, to further joint human spaceflight efforts. Over 60 Experiments in 18 Days: India's Space Science Milestone During the mission, the Ax-4 crew conducted over 60 scientific experiments, including several spearheaded by Shukla under India's research portfolio. These studies, designed by ISRO and top Indian research institutions, spanned space biology, AI, materials science, cognitive psychology, and sustainable food systems. One of the standout projects was the Sprouts Experiment, which examined how Moong beans and Fenugreek (Methi) germinate in microgravity. Though he couldn't eat the sprouts, the goal was to understand the changes in nutritional content, growth, and gene expression—critical for future space agriculture. Another key study involved stem cell research, testing if muscle regeneration could be accelerated using nutritional supplements in zero gravity—an experiment that could reshape both space medicine and treatments on Earth. He also led a psychological investigation called Voyager Displays, measuring how astronauts interact with screens and digital systems in space—data that could improve spacecraft and aviation interface designs. Further, Shukla worked on microalgae cultivation and studied tardigrades, microscopic creatures known for surviving extreme conditions, to understand their response to cosmic radiation and low temperatures. Dr Lucie Low: 'Thank You for Carrying the ISRO Portfolio' Dr Lucie Low, Chief Scientist at Axiom Space, who frequently interacted with Shubhanshu, lauded his performance. 'Thank you, Shux, for all your hard work doing science in the glove box and for the entire ISRO portfolio," she said, using his call sign. Her appreciation reflected the larger international admiration for Shukla's contributions to global space science during the mission. Back in Lucknow, A Family Prepares Despite the nerves, the Shukla family is preparing for Shubanshu's homecoming in their own way. 'His favourite dishes are already being planned," said Asha. 'It's our way of keeping hope alive. We'll feed him the food of home, of Earth." top videos View all As India awaits to welcome back its Gaganyatri, one home in Lucknow is already brimming with emotion, prayer, and anticipation. 'This is more than just a mission," Suchi said. 'It's the story of courage, science, and above all—faith. And for us, it's the story of our Shubhanshu's rebirth." view comments Location : Lucknow, India, India First Published: July 14, 2025, 15:00 IST News india 'It's His Rebirth': Tears & Prayers In Lucknow As Shubhanshu Shukla Makes Final Call From Space Disclaimer: Comments reflect users' views, not News18's.

India's Astronaut Shubhanshu Shukla Prepares To Return Home, ISS Undocking Today
Last Updated: The crew will return aboard SpaceX's Dragon spacecraft, with splashdown expected off the California coast on July 15 at around 3:00 pm IST Group Captain Shubhanshu Shukla, India's first astronaut to visit the International Space Station (ISS), is set to undock from the orbiting lab today at 4:30 pm IST. Shubhanshu Shukla participated in the Axiom-4 (Ax-4) mission along with three international crew members: Commander Peggy Whitson, and Mission Specialists Sławosz Uznański-Wiśniewski and Tibor Kapu. The crew will return aboard SpaceX's Dragon spacecraft, with splashdown expected off the California coast on July 15 at around 3:00 pm IST. Shukla's return marks the end of a landmark mission that highlighted India's growing role in international space collaboration and scientific research. During their 18-day stay on the ISS, the Ax-4 crew conducted over 60 scientific experiments across biology, AI, materials science, and human health. Among Shukla's key contributions was the Sprouts Project, which examined how microgravity influences seed germination and early plant growth — research aimed at supporting future space agriculture. He also led experiments on microalgae, assessing their ability to generate food, oxygen, and biofuels in space. Additionally, the crew tested glucose monitoring devices in microgravity to support future astronauts with diverse health needs. Other experiments included studies on mental health and evaluating next-generation spacesuit materials. Shukla had a video interaction with Prime Minister Narendra Modi and a phone call with ISRO Chairman V Narayanan during the mission, discussing scientific progress and the upcoming Gaganyaan human spaceflight project. At a farewell ceremony aboard the ISS on July 13, Shukla thanked ISRO, his crewmates, and the people of India. 'This mission is not just a personal milestone, but a proof to what humanity can achieve together. I hope our work inspires young minds in India and across the world to dream beyond boundaries," he said. Reflecting on India's space journey, Shukla added, 'Today, India looks ambitious from space, fearless, confident, and proud. India is still saare jahan se accha." Following undocking, the crew will spend approximately 21 hours travelling back to Earth. After splashdown, Shukla will undergo a week-long rehabilitation program to help his body adjust to gravity. His family is preparing a warm welcome as he returns home after making history. The Ax-4 mission is seen as a key step in India's preparations for the Gaganyaan mission and the country's broader ambitions in human spaceflight. view comments First Published: July 14, 2025, 08:41 IST Disclaimer: Comments reflect users' views, not News18's.

Hot Dogs To Fizzy Drinks: Study Reveals Fast Foods That Cut Minutes Of Your Life
Last Updated: A study by the University of Michigan revealed that eating just one hot dog could take away 36 minutes from your lifespan. We all love to indulge in fast food now and then. Whether it's a fizzy Coke on a hot day or mouthwatering hot dogs after a long day, fast foods are convenient, tasty, and comforting, but they might be costing you more than just calories. A new study from the University of Michigan has revealed shocking facts about some of these tasty fast foods. The study claimed that a glass of fizzy drink or a quick bite of a hot dog might take minutes of your life. One hot dog could take away 36 minutes from your lifespan, while drinking a single can of fizzy, sugary soda could shorten your life by 12 minutes, the study said. It highlighted that breakfast sandwiches and eggs may reduce life expectancy by 13 minutes each, whereas cheeseburgers by 9 minutes and bacon by 6 minutes. Researchers came to these conclusions after analysing over 5,800 foods and looking at the nutritional value of each of them and their link to diseases. They aimed to understand how diet affects life expectancy in measurable ways. Their findings revealed that although these ultra-processed foods are convenient and tasty, they are the real culprits to blame for a growing number of health problems. These ultra-processed foods are factory-made items loaded with refined sugar, unhealthy fats, salt, preservatives, and other artificial additives, which make them life-threatening if consumed every day over a long period. Previously, the British Medical Journal published a major study regarding the major risks caused by processed foods. Some of the key findings of the study include However, on the bright side, the University of Michigan study highlighted some foods that could add time to your life. For instance, nutrient-rich fish, which may add 32 minutes to your lifespan per serving. Additionally, fresh fruits, legumes, vegetables, nuts, and a variety of healthy cheeses are also great choices. view comments First Published: July 12, 2025, 19:45 IST Disclaimer: Comments reflect users' views, not News18's.
