According to Rio Tatsuki’s prediction, what is Nanakai Khurt Megakak and why it can be fatal for Japan, world news

Japan, one of the world’s most seismicly active countries, has approved a new comprehensive disaster preparation strategy with the aim of reducing the horrific effects of the anticipated Nanakai Thar Megakak. This is a long-standing initiative in response to scientific consensus that a powerful earthquake, possibly after a large-scale tsunami, is likely to strike with Nanakai Megathrust-A subdivision zone-in-decades away from the Pacific coast of thepa. Government estimates have warned that such an incident may cause 298,000 people to die and the worst condition may cause over 2.35 million buildings to be destroyed.As Economic timeThe Central Disaster Management Council led by the Japanese Prime Minister called in Tokyo to approve the new scheme. It updates the 2014 disaster guidelines and determines ambitious goals to reduce deaths by 80% in the next ten years and reduce losses by 50%. Here are the details of the original, scientific background, objectives and implementation mechanisms of Japan’s newest national strategy, which aims to provide a complete, fact-based photo of challenges and solutions related to one of the most important natural threats of the country.
‘New Baba Vanga’ predicts a horrific earthquake in Japan: what is Nanakai trough And why does it matter
The Nanakai trough is a deep beach located away from the southern coast of Japan, extending from Suruga Bay to Kyushu region. It marks the range where the Philippine C plate sub -parting under the Amurian plate, which makes it a highly active seismic area. Earthquakes generated by this mistake are known as Nanakai Megathrust Earthquake and are the most powerful and harmful in Japanese history.Historically, the Nanakai trough has produced large -scale earthquake pairs in about 90 to 200 years. Major events include:
- 1707 Hoi Earthquake
- 1854 ansei-tōkai and ansei-nankai earthquake (one day separated)
- 1944 tanning earthquake
- 1946 Nanakido Earthquake
Given this cyclic pattern, scientists believe that Japan is now in the window for another major event. Possible human and economic tolls are particularly dangerous in cities such as Osaka, Nagoya, and Shizuoka with densely populated Pacific coast.
Government’s new disaster preparation scheme (2025)
The updated plan given in 2025, replaces the previous structure set up in 2014. The major goals are:
- Reduce incompatibility by 80%
- Cut structural damage up to 50%
- Increase initial warning and withdrawal procedures
- Strengthen important infrastructure in high -risk areas
The plan focuses on both earthquake preparations and tsunamis flexibility, which reflects the dual threats generated by the Nanakai trough rupture.200 target remediesThe plan underlines 200 specific goals, which will be evaluated annually. This includes:
- Retropheat
- Extension and upgradation of tsunami withdrawal towers
- Improves initial warning systems using AI and satellite data
- Equivalent drill frequency is increasing in risky municipalities
- Emergency supply reserves in coastal shelters
Local governments are expected to apply these goals with financial and logical support from the central government.
Japan warns of Nankai trough megakek: risk up to 298,000 lives
The Cabinet Office of the Japanese government modeling several scenarios in March 2025 based on various magnitude and pattern of breakdown. A magnitude 9-class with Nanakai trough includes the worst condition for earthquakes:298,000 deaths including tsunami casualties2.35 million buildings were destroyed, mostly in Southern Honshu and ShikokuEconomic Loss (Over 220 trillion (about $ 1.4 trillion USD)Tsunami waves reach heights of more than 30 meters in some areasThese estimates include previous events and current population density, including lessons learned from the 2011 Great East Japan earthquake, killing around 20,000 people.
Japan’s Baba Wanga Rio Tatsuki’s prediction and public response
Parallel to scientific concerns, Rio Tatsuki’s predictions have attracted public attention, a Japanese manga artist is sometimes called “New Baba Vanga”. The Tatsuki, alleged for the allegedly accurate past forecasts, predicts a huge seabed crack between Japan and the Philippines, triggering a tsunami three times larger than a 2011 disaster.Although the warning of the Tatsuki is not supported by scientific evidence, he has promoted concern on social media and urged the national preparation conversations. The authorities have neither confirmed nor rejected its claims, but have continued the base policies on geological and seismic data.
Structural and social preparation measures
Infrastructure flexibility
- High -risk housing in coastal provinces will be retrofitted by 2030.
- The tsunami shelters will be expanded and raised to accommodate the high wave model.
- Hospital, school and public transport hubs will undergo seismic reinforcement.
- The emergency communication network will be upgraded for post-co-coordination.
Community readiness
- Withdrawal exercises in schools and workplaces will compulsorily become.
- Community watch programs will be funded to help the elderly and disabled during the emergency.
- The mobile alert system will be updated to cover the more accurate GPS-trigger warning.
Implementation and inspectionThe scheme will be coordinated by the Central Disaster Management Council of the Cabinet Office, with cooperation:
- Japan Meteorological Agency (JMA)
- Ministry of Land, Infrastructure, Transport and Tourism (MLIT)
- Firelike Management Agency (FDMA)
- Local municipal officer
Each of 200 goals will be reviewed annually, and the progress report to maintain transparency and public accountability will be presented to the diet (Japanese Parliament).
Looking forward: commitment to Japan’s flexibility
Japan’s new disaster plan represents an important step in the ongoing efforts of the country to protect life and infrastructure in front of unavoidable natural threats. One of the world’s most advanced seismic monitoring systems and familiar with a culture familiar with the risk, Japan is one of the most deadly natural phenomena in modern history that is trying to combine technological innovation, historical knowledge and local engagement.As the country prepares for a future that will almost certainly include another Nanakai trough megakak, the success of this scheme will not only depend on government funding and scientific forecasts, but will also depend on the desire to engage in a nationwide culture of readiness even on the will of the citizens.
