Was there a tsunami today while you slept and did it hit California? What happened will shock you
If you woke up today to see 'Tsunami California' trending everywhere, you're not alone. Social media exploded overnight with shocking headlines suggesting a tsunami may have hit California while most people were still sleeping. But what really happened? Was there a real tsunami? Did it hit the California coast? Or was it just another false alarm that caused panic online?
Was there really a tsunami warning in California today?
Yes—but it's not as dramatic as many viral posts made it seem. According to the U.S. National Tsunami Warning Center (NTWC), an early-morning seismic event in the Pacific Ocean triggered a brief tsunami alert for parts of the California coastline. This was a precautionary measure, issued after an undersea earthquake was detected off the coast near the Pacific Rim.

The warning was meant to alert local authorities and residents near vulnerable coastal zones—but no large waves were ever reported, and the alert was later downgraded.
What triggered the tsunami alert in the first place?
The potential tsunami scare began after a
6.7 magnitude earthquake
struck deep beneath the ocean floor, not far from the Aleutian Islands of Alaska. While this is far from California, such undersea quakes often trigger automatic tsunami models that predict potential wave movements across the Pacific basin.
Within minutes, agencies were analyzing the data to assess whether coastal areas—including
California, Oregon, and Washington
—could face any impact.
Live Events
Did the tsunami actually hit the California coast?
No. There was no actual tsunami that hit California today.
Despite some misleading headlines and viral videos circulating online, California's coastal cities like Los Angeles, San Diego, San Francisco, and Santa Barbara remained unaffected. No flooding, no giant waves, no destruction.
Officials at the NTWC and the California Office of Emergency Services confirmed that the alert was purely precautionary and was canceled shortly after updated data showed no significant threat.
Quake Epicenter was off Kamchatka Coast, comparable to 2011 Japan earthquake
According to the United States Geological Survey (USGS) and Russian seismic authorities, the earthquake occurred around 75 to 80 miles southeast of Petropavlovsk-Kamchatsky, a city on the Kamchatka Peninsula in Russia's Far East. The depth of the quake was reported between 12 and 21 kilometers, which is relatively shallow and increases the likelihood of severe tsunami activity.
This event has drawn comparisons to the 2011 Tōhoku earthquake in Japan, which also caused a devastating tsunami and nuclear disaster. In terms of sheer force, it ranks among the strongest earthquakes ever recorded.
Tsunami waves up to 5 meters batter Russian coastal towns
In Russia, the brunt of the quake's impact was felt in coastal regions such as Severo-Kurilsk and other areas along the Kuril Islands. Local officials reported tsunami waves between 3 and 5 meters (roughly 10 to 16 feet). Video footage and eyewitness accounts revealed seawater surging inland, damaging homes, sweeping vehicles off roads, and causing widespread panic.
A state of emergency was declared in the North Kuril District, and more than 2,700 residents were evacuated to higher ground. Several people sustained injuries during tremors and emergency evacuations, though no fatalities have been confirmed as of now.
Local hospitals continued to operate through the crisis, with viral videos showing doctors performing surgeries even as walls shook, prompting praise for their bravery online.
Japan orders evacuation of over 2 million amid tsunami alerts
In neighboring Japan, authorities acted swiftly, issuing tsunami advisories across multiple coastal prefectures. Over 2 million people were advised to evacuate in low-lying regions, especially in parts of Hokkaido, Tohoku, and coastal Chiba.
While the waves that reached Japan were significantly lower than those in Russia, they still caused disruption. Recorded wave heights included:
60 cm
in Hokkaido
50 cm
at Ishinomaki Port
40 cm
at Kuji Port
20 cm
in
Tokyo Bay
Train services were suspended, and ports temporarily closed as a precaution. The Fukushima Daiichi nuclear plant, along with other nuclear facilities, was inspected and deemed safe after temporary evacuations.
Hawaii experiences tsunami waves, issues evacuation alerts
In the United States, Hawaii was among the first to activate tsunami warning sirens. Emergency management officials confirmed that waves as high as 1.7 meters (nearly 5.5 feet) hit parts of the Hawaiian Islands.
Communities along Maui, Oahu, and the Big Island were urged to evacuate coastal zones and move to higher ground. Roads were cleared for emergency access, and some private properties, including Oprah Winfrey's estate, reportedly opened access roads to assist with evacuations.
By late afternoon, tsunami warnings for Hawaii were downgraded to advisories as wave activity subsided. However, residents were still urged to stay away from beaches and harbors due to strong, unpredictable currents.
US West Coast and Canada remain on alert for aftershocks and wave surges
Across the U.S. West Coast—including California, Oregon, Washington, and Alaska, as well as British Columbia in Canada—tsunami watches and advisories were issued within hours of the quake. While waves in these regions were milder, ranging from 30 to 50 cm (1 to 1.5 feet), emergency authorities warned of dangerous riptides and erratic tidal surges.
In Crescent City, California, a region historically affected by tsunamis, minor flooding was reported in the harbor. Coastal residents were urged to remain on alert due to the possibility of multiple wave surges.
Tsunami watches issued across Pacific Islands and Asia-Pacific nations
The quake's massive energy sent ripples across the Pacific, prompting tsunami watches or warnings in countries including:
Mexico, Peru, and Ecuador
on the Pacific coast of South America
Philippines, China, Taiwan, and Vietnam
Guam, Micronesia, and the Marshall Islands
New Zealand and Australia's east coast
Many of these alerts were downgraded within 6–12 hours after the initial quake, though emergency services in each country maintained a high state of readiness in case of aftershocks or delayed tsunami waves.
Multiple tsunami waves possible, residents urged to stay vigilant
Experts have repeatedly emphasized that tsunamis rarely involve a single wave. Instead, multiple waves may arrive over several hours, and later waves are often larger and more destructive than the first. This was evident during the 2004 Indian Ocean and 2011 Japan tsunamis.
Authorities in all affected regions reminded the public to stay away from coastal areas until official all-clear notices were issued. Currents remain unpredictable, and even small surges can knock people off their feet or capsize boats.
Emergency preparedness tested across borders
The quake provided a real-world stress test for regional early warning systems and international disaster coordination. Within minutes of the earthquake, agencies like the Pacific Tsunami Warning Center, Japan Meteorological Agency, and national weather services from the U.S., Canada, and Russia activated layered response systems.
The quick issuance of alerts, timely evacuations, and real-time information dissemination via social media and official apps helped prevent mass casualties despite the enormous magnitude of the disaster.
Massive earthquake shows how vulnerable the Pacific rim remains
The
July 30, 2025 Kamchatka earthquake
is a chilling reminder of how vulnerable Pacific Rim nations are to seismic activity. Although no major fatalities have yet been reported, the scale of the earthquake and its resulting tsunami waves caused widespread damage, fear, and disruption across Russia, Japan, Hawaii, and the Americas.
As aftershocks continue, scientists and emergency planners are reviewing data to refine early-warning systems and ensure communities are better prepared for future events.
FAQs:

Researchers flag critical gaps in Wayanad's disaster warning system
Kozhikode: A joint research by experts from IIM Kozhikode, NIT Calicut, IIT Bombay and Keio University, Japan has found technological shortfalls, institutional disconnects and community exclusion in Wayanad's disaster early warning system. Examining the 2024 Chooralmala-Mundakkai landslide, the researchers have sought a thorough rethink of disaster resilience strategies in view of climate uncertainties. The report, titled "Wayanad Landslides 2024: Early Warning System - Changing the Last Mile to the First Mile", followed collaborative field investigation in Jan 2025 and interviews with local communities and stakeholders at different intervals. It offers insights into the vulnerabilities of Kerala's fragile hill ecosystems and calls for embedding community participation at the core of resilience-building and policy design. On the technological front, the report says the current EWS infrastructure in Wayanad lacks real-time data collection, predictive accuracy and effective last-mile dissemination. "Despite isolated initiatives like IoT-based sensor networks, systemic gaps remain in coverage scalability and integration," it says. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Become Fluent in Any Language Talkpal AI Undo Flagging institutional disconnects, it says the existing governance model, though robust on paper, falters in coordinating local bodies, technological agencies and community actors. It notes that bureaucratic delays, fragmented responsibilities and lack of localized protocols hamper swift action. It highlights the need for enhanced community engagement, while noting that early warnings often fail to translate into community action. It calls for a paradigm shift - from viewing early warning as a technological end-point to embedding it within the social fabric of vulnerable communities. It advocates repositioning the "last mile" of communication as the "first mile" of resilience-building. It suggests that schools can be made its local hubs, with teachers as ambassadors and students as information carriers. "The approach calls for integrating traditional knowledge, localized risk mapping, participatory drills and strengthening institutional protocols at the grama panchayat level," the report says. It recommends fast-tracking the installation of X-Band Doppler weather radars and low-cost IoT sensor networks in Wayanad, along with the mandatory inclusion of disaster preparedness modules in school curricula. The other recommendations include establishing "early warning focal points" in every ward; integrating local volunteers, educators and administrative personnel; and recalibration of state-wide disaster management policies to emphasize hyperlocal, community-led action. Developing an "all-hazard early warning system"" (AHEWS) that integrates rainfall thresholds, soil moisture data, terrain mapping and real-time landslide monitoring technologies; and localized risk mapping and zonation and updating landslide susceptibility and hazard zonation maps using high-resolution remote sensing and geospatial data have also been recommended. "These should be made available to local authorities and the public for informed planning and response," it says. The report also calls for alerts through loudspeakers, community radio, mobile-based messages and SMS services in local languages; capacity building and culturally sensitive community engagement through school-based disaster education; active involvement of panchayat raj institutions, self-help groups and tribal communities. There should be stronger coordination among the India Meteorological Department (IMD), Geological Survey of India (GSI), Kerala State Disaster Management Authority (KSDMA) and district-level authorities, it says. On the infrastructure front, it recommends installing automated rain gauges, geotechnical sensors and slope movement detectors in high-risk zones and encouraging the use of AI and machine learning for predictive modelling and anomaly detection. The researchers were from India-Japan Centre on Climate and Culture at IIM-K, Centre for Climate Resilience and Disaster Management at NIT-C, Centre for Technology Alternatives for Rural Areas at IIT-Bombay and India Japan Laboratory (IJL) at Keio University. The field visits were led by Prof Rajib Shaw of IJL. Stay updated with the latest local news from your city on Times of India (TOI).

80 years after Hiroshima: Nuclear threat still looms over global security
History, with its grim cycles and painful lessons, has every reason to indict humanity. In the week marking the 80th anniversary of the US atomic bombings of Hiroshima and Nagasaki, Russia announced it no longer considers itself bound by the 1987 Intermediate-Range Nuclear Forces Treaty, blaming 'the actions of Western countries' for creating a 'direct threat' to its security. Last Friday, US President Donald Trump said he had ordered the deployment of two nuclear submarines 'in appropriate regions' following what he described as 'highly provocative comments' by former Russian president Dmitry Medvedev. STORY CONTINUES BELOW THIS AD It is ironic that nuclear weapons still exist, despite the well-known devastation they cause to the planet—and the threat of nuclear sabre-rattling remains as constant as the air we breathe. Aside from white lilies and sombre memorial services for the dead, and sympathy for those emotionally and physically maimed by the two blasts in Hiroshima and Nagasaki, little has moved forward in practical terms. In the prologue of her book Nuclear War: A Scenario, Annie Jacobsen describes a frightening vision of what the next nuclear bomb explosion might look like. For now, it is only imagination—but reality would unfold within minutes if the bombs were ever detonated, for whatever reason. She writes: 'A 1-megaton thermonuclear weapon detonation begins with a flash of light and heat so tremendous it is impossible for the human mind to comprehend. One hundred and Eighty million degrees Fahrenheit is four or five times hotter than the temperature that occurs at the center of the Earth's sun. In the first fraction of a second this thermonuclear bomb strikes… there is light…. Soft X-ray light with a very short wavelength. The light superheats the surrounding air to a millions of degrees, creating a massive fireball that expands at millions of miles per hour. Within a few seconds, this fireball increases to a diameter of a little more than a mile (5,700 feet across), its light and heat so intense that concrete surfaces explode, metal objects melt or evaporate, stone shatters, humans instantaneously convert into combusting carbon.' This, of course, is Jacobsen's speculative scenario of what might happen if a nuclear bomb were to strike the Pentagon outside Washington. But if such an event were to occur, her imagined horror would become exact, unbearable reality. In the 653-page book The Effects of Nuclear War, authored along with Philip J Dolan, Samuel Galsstone writes, 'There are inherent difficulties in making exact measurements of weapons effects. The results are often dependent upon circumstances, which are difficult, and sometimes impossible, to control even in tests and would certainly be unpredictable in the event of an attack.' STORY CONTINUES BELOW THIS AD Then, after the immediate destruction there is the curse of a nuclear winter which is inevitable. A legacy of devastation, a present of peril Eighty years after the atomic bombings of Hiroshima and Nagasaki, which killed more than 200,000 people and left haunting reminders of nuclear warfare, the world remains on edge. Far from fading into the pages of history, nuclear weapons continue to cast a long, ominous shadow over global peace and security. While the world has avoided another nuclear strike since 1945, today's risks may be even more acute driven by geopolitical volatility, advancing technologies and the slow unravelling of disarmament frameworks. A world still armed to the teeth As of early 2025, the global stockpile of nuclear warheads stands at approximately 12,241, with the vast majority—over 90 per cent—held by United States and Russia. This massive arsenal is not just a relic of the Cold War but a continually modernised force, featuring increasingly sophisticated delivery systems and warhead designs, Andrew Hammond writes in The Business Times. While global treaties have aimed to curb proliferation, they have done little to dismantle the core of existing nuclear forces. Slowing clock of disarmament The post-Cold War era witnessed a surge of hope for nuclear disarmament. Treaties such as the Strategic Arms Reduction Treaty (Start) and initiatives like the Nuclear Security Summits led to tangible reductions and enhanced controls over nuclear materials. However, this progress has since slowed, if not reversed. Today, the momentum has shifted towards rearmament. The United States is developing a new generation of nuclear weapons and has indicated an openness to resuming nuclear testing. Meanwhile, China has more than tripled its arsenal, reaching around 600 warheads. These developments have reignited fears of a new arms race, especially as Russia also pursues advanced systems like hypersonic missiles and underwater nuclear drones. Submarines are indeed deadly platforms for nuclear launches. Efforts such as the Treaty on the Prohibition of Nuclear Weapons (TPNW), which came into force in 2021, have garnered support from many non-nuclear states. Yet, they have been largely dismissed by nuclear-armed nations. The global appetite for disarmament, once buoyed by the horrors of Hiroshima, is faltering in the face of renewed strategic competition. STORY CONTINUES BELOW THIS AD Tensions in a fragile world Geopolitical fault lines are increasingly volatile, exacerbating the risk of nuclear conflict. Recent exchanges between Medvedev and Trump over nuclear threats serve as stark reminders of how easily diplomatic tensions can veer into dangerous territory. Medvedev's reference to Russia's 'Dead Hand' nuclear retaliation system and Trump's counter by repositioning submarines closer to Russia are not just posturing, they reflect the peril of miscalculation in today's hyper-charged political climate. Other hotspots, including the enduring India-Pakistan conflict and North Korea's relentless nuclear testing, add layers of complexity. These regions combine deep-seated historical animosities with nuclear capabilities, making them particularly susceptible to escalation. Iran, for its part, remains a significant concern. Reeling from attacks on its nuclear facilities, Tehran may further accelerate its nuclear programme, potentially pushing other regional powers like Saudi Arabia and Turkey toward similar ambitions. Technology: The new wildcard While nuclear weapons have always embodied existential danger, emerging technologies are making the nuclear scenario even more unpredictable. Artificial intelligence, cyber warfare and advanced missile defence systems are disrupting the traditional logic of nuclear deterrence. According to Hammond, AI-driven systems, if poorly managed, could make decisions faster than human operators can verify, increasing the likelihood of misjudgements. Meanwhile, cyberattacks on nuclear command and control systems could trigger false alarms or disable safeguards. The potential for accidental launches or misinterpreted threats has grown significantly in an era of digital warfare and machine decision-making. STORY CONTINUES BELOW THIS AD During the Cold War and into the 1990s, several false alarms nearly triggered nuclear war due to technical errors and misinterpretations. In the 1950s, a flock of Canadian geese was mistaken for a Soviet bomber attack by radar systems. The 1960s saw meteor showers and radar reflections from the moon falsely indicating a missile strike, while in 1979, a human error led to a false nuclear alert, causing Norad (North American Aerospace Defense Command) to scramble fighter jets. A year later, a faulty computer chip triggered a similar scare, prompting the preparation of B-52 bombers and the President's emergency aircraft. The most serious incident occurred in 1995 when a Norwegian research rocket was misidentified by Russian systems as a US nuclear missile, prompting president Boris Yeltsin to consider a retaliatory strike, an act he ultimately resisted, narrowly avoiding catastrophe. Terrorism threat Beyond state actors, the threat of nuclear terrorism has not disappeared. While acquiring a functional nuclear weapon remains a high barrier for non-state groups, the possibility of a radiological dispersal device (dirty bomb) is far more feasible. Such a weapon would use conventional explosives to spread radioactive material, potentially causing mass panic, economic chaos and long-term contamination of urban centres.. Hammond mentions former US defence secretary Robert Gates who once remarked that the thought of a terrorist obtaining a nuclear weapon was what kept him awake at night. STORY CONTINUES BELOW THIS AD Treaties undermined, norms at risk International treaties and arms control frameworks that once served as guardrails are now fraying. The Doomsday Clock, maintained by the Bulletin of the Atomic Scientists, was set just one second from midnight earlier this year, the closest it has ever been to global catastrophe. Eighty years after Hiroshima, the world faces a dual nuclear threat: that of state-led warfare and non-state terrorism. While the horrors of 1945 forged a powerful global aversion to nuclear war, that consensus is under threat. The only way to ensure nuclear weapons are never used again is to eliminate them altogether. Eight decades on, the urgency of that mission has never been clearer.
