Scary tsunami waves, volcanoes and earthquakes… the Pacific ‘Ring of Fire' proves dangerous again
Several people in Russia were injured and the coast recorded a 3-4 metre (10-13 feet) high tsunami wave, according to Sergei Lebedev, regional minister for emergency situations, Reuters reported.
Further, tsunami alerts have been issued by Japan for its east coast, the United States for Hawaii and the west coast, and the various Pacific Islands.
The US Geological Survey (USGC) in its report said the earthquake occured at a shallow depth of 19.3 km (12 miles), and was centred 119 km (74 miles) east-southeast of Petropavlovsk-Kamchatsky, a city of 1,65,000 people.
Further, the US Tsunami Warning System also issued a warning of 'hazardous tsunami waves' exceeding 3 metres (10 feet) in height, within the next three hours.
Some regions it gave alerts for include: the coasts of Ecaudor, Chile, Hawaii, Japan, Russia, the Solomon Islands and much of the Pacific, and the US west coast, including Alaska.
Russia's eastern region, including the affected Kamchatka Peninsula lie in the geologically active area known as the 'Pacific Ring of Fire'. The region is highly prone to earthquakes and volcanic eruptions.
An arc of seismic faults, the 'Ring of Fire' saw two large earthquakes in 2009, which triggered tsunami waves that killed at least 192 people in Samoa, American Samoa and Tonga, according to an AP report.
In 2011, the eastern coast of Japan was evacauated following a devastating earthquake in the region that caused the Fukushima disaster.
Geographically, the Pacific Ocean's Ring of Fire extends from Russia and Japan in the east, to the US west coast, and volcanoes in frozen south in Antarctica, including Mount Erebus, the southernmost volcano on Earth. Ocean trenches are also part of the Ring of Fire. This is why a major eruption or earthquake in the region triggers warnings across the globe. Ring of fire map: The area ranges the entire north coast of Antarctica, east coast of Asia and New Zealand, and west coasts of South America, North America and multitude of Pacific Islands scattered across the vast ocean, with the Bering Sea to the north. Note: Above map excludes Antarctica.
Notably, the Russian Academy of Sciences said today's quake is the strongest to hit the region since 1952.
Danila Chebrov, director of the Kamchatka Branch of the Geophysical Service, posted on Telegram, 'Aftershocks are currently ongoing ... Their intensity will remain fairly high. However, stronger tremors are not expected in the near future. The situation is under control.'
According to a National Geographic education post, the Ring of Fire is a 40,000 km horseshoe shaped region housing 452 volcanoes from the southern tip of South America, up along the coast of North America, across the Bering Strait, down through Japan and into New Zealand, and further south in Antarctica.
The geographic activity is due to constantly shifting of tectonic plates either causing earthquakes or volcanic eruptions along the fault lines. Some notable volcanoes in the belt include Antarctica's Mount Erebus, Mt Fuji in Japan, and Mount St Helen's in Washington, US.

Days after major earthquake, dormant Russian volcano erupts for first time in centuries—Scary footage surfaces
Following one of the powerful earthquakes on record strike the region, a volcano in Russia's eastern Kamchatka region has erupted for the first time in 450 years, according to its emergency authority. The Smithsonian Institution's Global Volcanism Programme said the Krasheninnikov volcano, dormant since its last eruption in 1550, has now spewed a massive plume of ash, as shown in images released by Russian state media. Kamchatka's Ministry of Emergency Situations stated on Telegram that the ash plume reached an estimated height of 6,000 meters (19,700 feet). The ministry mentioned, 'The plume is spreading eastward from the volcano toward the Pacific Ocean. There are no populated areas along its path, and no ashfall has been recorded in inhabited localities.' The ministry added that the volcano has been classified with an "orange" aviation hazard code, signaling potential flight disruptions in the area. This event occurred shortly after the eruption of Klyuchevskoy, the tallest active volcano in Europe and Asia, which erupted on Wednesday. The Global Volcanism Programme notes that Klyuchevskoy eruptions are relatively frequent, with at least 18 occurring since 2000. Both eruptions followed one of the most powerful earthquakes ever recorded on Wednesday, which led to tsunami alerts and forced millions of people to evacuate coastal regions from Japan to Hawaii to Ecuador. Officials said that the most severe damage occurred in Russia, where a tsunami swept through the port of Severo-Kurilsk and flooded a fishing plant. The magnitude 8.8 earthquake hit near Petropavlovsk on Russia's Kamchatka Peninsula and was the powerful since the 2011 magnitude 9.1 quake off Japan, which triggered a tsunami that claimed over 15,000 lives. The scientists said Pacific Plate's movement makes the Kamchatka Peninsula, located off Russia's Far East coast, particularly vulnerable to earthquakes, and they warned that larger aftershocks remain possible, Reuters reported. Centered near the city of Petropavlovsk-Kamchatsky, this was the largest earthquake since the catastrophic 2011 Tohoku quake, which triggered a tsunami that led to the meltdown at Japan's Fukushima Daiichi nuclear plant. "The Kamchatka seismic zone is one of the most active subduction zones around the Pacific Ring of Fire, and the Pacific Plate is moving westwards at around 80 mm (3 inches) per year, Roger Musson, honorary research fellow at the British Geological Survey said.

AI for climate resilience and environmental monitoring
India navigates the twin frontiers of our time, which are escalating the climate crisis and a fast-evolving technological revolution. It holds a powerful opportunity to lead the world in crafting climate resilience through Artificial Intelligence (AI). With the nation co-chairing major AI-environment task forces at the UN and G20, this is more than a moment of influence; it is a call to action. AI, when paired with satellite data, can be our eyes in the sky and our early warning system on the ground for tracking deforestation in real time, predicting floods before they strike, and holding polluters accountable with data-driven precision. But to unlock this promise, we must build a framework that is not just tech-savvy but also just, transparent, and accessible to all. The future of climate action is digital, and India has the chance to code it right. AI(REUTERS) According to the World Meteorological Organization (WMO) and other UN organisations, India suffers an estimated annual loss of around $87 billion due to climate-related disasters, which is a staggering figure that underscores the urgency of predictive and preventive climate action. From heatwaves in Delhi to deadly cyclones along the eastern coast, the impact is felt in each part of the nation with growing intensity. In this situation, AI, when used with remote sensing technologies and geospatial satellite data, can lead to a transformative change. AI can be a silent watcher, keeping an eye on ecosystems in real time and spotting illegal logging, shrinking mangroves, glacier retreat, and forest fires with unmatched speed and accuracy. Tools such as Google Earth Engine, along with indigenous systems like India's Bhuvan and RISAT satellites, generate the crucial data, which AI algorithms may swiftly process to flag environmental threats. Beyond this monitoring, the Machine Learning and Deep Learning Models can reimagine the manner in which we predict disasters today by analysing historical weather trends, soil conditions, and atmospheric changes to forecast floods, landslides, and cyclones, saving thousands of lives. AI is enhancing emissions tracking by monitoring pollution from factories, traffic, and agricultural practices in near real-time, which will ensure India's carbon accounting remains accurate and aligned with its Nationally Determined Contributions (NDCs) under the Paris Agreement. While AI holds great promise for climate resilience, making it a reality takes more than just technology and data. It demands a supportive ecosystem, one that includes real-world pilots, forward-looking policies, inclusive economic planning, and strong collaboration across sectors. Several promising case studies and strategic pathways show how India can lead by example. In Tamil Nadu, an AI-based flood forecasting model has already helped predict urban flooding with greater accuracy, aiding disaster preparedness in Chennai. AI-powered systems, like the one launched in the Pench Tiger Reserve Pantera in Maharashtra, can distinguish between smoke and clouds, reducing false alarms. These systems use infrared technology to detect fires both day and night, enabling 24x7 monitoring. AI is transforming emission tracking and climate resilience globally, from India's AI flood forecasting in Tamil Nadu and fire detection in Maharashtra to G20 innovations like the US's electric vehicles and Brazil's AI-driven deforestation monitoring, highlighting the need for supportive policies and cross-sector collaborations. In parallel, India can spearhead South-South collaboration to tailor AI models for tropical, drought-prone, and monsoon-affected landscapes. Under the G20's push for inclusive AI governance, building a Global South Working Group and a shared AI knowledge hub can democratise access to computing resources, datasets and regulatory best practices. Prime Minister (PM) Narendra Modi outlined India's AI vision at the G20, one that promotes inclusivity and global equity in addition to innovation. In order to guarantee that AI development is open, equitable, and available to all countries, not just a select few, he urged the establishment of strong international standards. According to Modi, ethical AI governance must put developing nations' particular needs first, enabling them to overcome historical obstacles and advance sustainable development, renewable energy, and climate resilience. To translate the promise of AI into a tangible impact for climate resilience, India must take a multi-pronged approach. First, integrating AI into national climate policy is crucial. Missions under the National Action Plan on Climate Change (NAPCC), such as those focused on Himalayan ecosystems and sustainable agriculture, offer fertile ground for AI-powered scale-ups. With tools like satellite imaging, predictive analytics, and remote sensing, these missions can benefit from sharper decision-making and real-time responsiveness. Second, institutional capacity must be strengthened. Platforms like NITI Aayog, IndiaAI, the Global Partnership on Artificial Intelligence (GPAI), and NEERI's Sustainovate 2025 can catalyse mentorship and scalable innovation. Third, India must actively launch supportive pilots and regulatory frameworks. Successful models like AI-led flood forecasting in Chennai, heat vulnerability mapping in Delhi, and wildfire detection in the Pench Reserve must be scaled across other states through inclusive funding and smart governance mechanisms. Equally important is the need to safeguard transparency and equity. This means building open-access AI data ecosystems, mandating climate impact disclosures, embedding community-driven indices into AI decision frameworks, and ensuring that marginalised groups are neither excluded nor further disadvantaged. Finally, India must champion South–South collaboration. By operationalising PM Modi's G20 satellite mission proposal, India can help pool sensing, processing, and AI resources to create a shared digital public good for the Global South. This will not only democratise access to cutting-edge climate technologies but also foster a more equitable, cooperative, and resilient planetary future. Innovation alone is not enough; it must be backed by strong institutional will. For India to lead in AI-driven climate resilience, it must take decisive policy steps. First, the government should incentivise the development of clean and sustainable AI infrastructure through targeted subsidies, green procurement policies, and energy-efficient data centres. Second, fostering cross-border AI collaboration through platforms like the G20, GPAI, and South–South partnerships is essential to share knowledge, tools, and technologies tailored to diverse climatic challenges. Finally, India must embed data justice into its AI frameworks by ensuring that socio-environmental equity becomes a foundational principle in AI design, deployment, and governance. The future of climate action is digital, and India now stands at a pivotal moment to code that future with foresight, fairness, and purpose.
