Greater than 1,300 earthquakes have hit Japan’s Tokara Islands in two weeks, prompting evacuations of dozens of residents from the distant archipelago on the nation’s southern tip.
Though no main injury has been reported and no tsunami warnings have been issued, the Japan Meteorological Company has cautioned that tremors as robust as a “decrease 6” on Japan’s seven-stage seismic depth scale — equivalent to one which occurred Thursday — could proceed.
Decrease 6 signifies an depth that will make it tough for individuals to face with out holding on to steady help.

“The seismic exercise stays dynamic,” JMA official Ayataka Ebita stated at a information convention Sunday — and that has fueled fears of a megaquake.
The temblors have coincided with viral panic stemming from the 2021 reprint of a comic book guide that many are actually decoding as a clairvoyant prediction of a serious earthquake. “The true catastrophe will are available in July 2025,” learn the duvet of manga artist Ryo Tatsuki’s “The Future that I Noticed.” The graphic novel, which explores Tatsuki’s goals, additionally incorporates a panel that claims “the ocean flooring between Japan and the Philippines will crack.”
In current months, that prediction has turn into the topic of intense on-line hypothesis. It has even unfold to close by international locations like Hong Kong, the place it has been blamed for a current dip in tourism to Japan.
Final month, Hong Kong Airways suspended all flights to the southern Japanese prefectures of Kagoshima and Kumamoto, citing low demand.
In South Korea, earthquake panic has been cited as a purpose for the cheapness of flights to Japan in contrast with final yr, though business specialists have stated that there are different components at play: elevated competitors between airways and a stronger yen that reduces the shopping for energy of South Korean vacationers.
On Saturday, South Korean singer Taemin of the band SHINee, who was in Japan for a live performance, referenced Tatsuki’s prediction in a livestream, assuring followers he was protected and jokingly saying an earthquake may make his efficiency “look cool.”
However confronted with backlash for making mild of a pure catastrophe, he later issued an apology in Japanese and Korean.
There’s a purpose why a comic book guide’s scientifically baseless prediction is at present gaining a lot traction: Tatsuki was (kind of) proper earlier than. The primary version of the graphic novel, revealed in 1999, referenced a “large catastrophe” in March 2011 and contained traces like: “I dreamed of a terrific catastrophe. The waters of the Pacific Ocean south of the Japanese archipelago will rise.”

That prediction appeared to return true with the huge 2011 Tohoku earthquake, which killed over 19,000 individuals and triggered the tsunami that led to the Fukushima nuclear catastrophe. At an estimated $360 billion incurred in financial damages, the earthquake stays one of many costliest pure disasters in historical past. It registered 9.0 on the Richter scale, which measures the magnitude of the earthquake. Shindo, Japan’s seismic depth scale, measures depth at a selected location.
The coincidence catapulted Tatsuki to fame and made her manga a bestseller.
However in current weeks, Tatsuki has tried to quell the panic over her newest prediction, saying in a press release issued by her writer that she was “not a prophet.”
“I imagine that everybody must be free to make their very own interpretation,” she advised Japan’s Mainichi newspaper in Might. “Nonetheless, I believe it is very important not get overly swept up within the course of and to behave appropriately in consideration of professional opinion.”
Japanese authorities officers and scientists have taken pains to debunk the theories, stressing that it’s scientifically unimaginable to foretell earthquakes with such accuracy.
“It’s completely a coincidence. There is no such thing as a causal connection,” stated Ebita of the JMA on Saturday. “In Japan, earthquakes can occur at any time. Please be ready, at all times.”

Japan is without doubt one of the most earthquake-prone international locations on the planet, given its location inside the Pacific Ring of Fireplace, a 25,000-mile-long belt of seismic and volcanic sizzling spots that loops across the perimeter of the Pacific Ocean, together with the U.S. West Coast.
The nation experiences about 1,500 earthquakes a yr, or almost a fifth of the world’s complete, and earthquake evacuation drills are often practiced by authorities companies and public colleges.
On New Yr’s Day final yr, a magnitude 7.5 earthquake in Noto Peninsula in central Japan led to over 500 deaths and destroyed or broken no less than 37,000 houses.
As a result of they sit astride two overlapping tectonic plates, the Tokara Islands have lengthy been vulnerable to seismic exercise equivalent to “earthquake swarms,” a burst of comparatively minor earthquakes occurring in fast succession that may last as long as a number of months. (Southern California is one other frequent website of earthquake swarms, although many are so minor they’re barely perceived.)
The archipelago spans 12 particular person islands — simply seven of that are inhabited by a mixed 660 or so residents — and the present swarm of quakes there may be probably the most substantial since 1995. Two current swarms that occurred in 2021 and 2023 exceeded simply over 300 quakes every.
Though it’s unclear why the present swarm is a lot higher than these situations, Takuya Nishimura, an earthquake professional at Kyoto College’s Catastrophe Prevention Analysis Institute, says it could be a results of volcanic exercise.
“I think the subsurface motion of magma brought about extreme earthquake exercise,” he stated. “A number of previous research present submarine volcanoes across the swarm area, which suggests the existence of magma beneath the bottom.”

Regardless of the present viral consideration across the Tokara swarm, specialists like Nishimura are extra involved with one other, way more credible earthquake forecast that has loomed over the nation for years.
Earlier this yr, a authorities panel estimated that there’s an 80% likelihood of a magnitude 8 to 9 megaquake on the Richter scale occurring alongside Japan’s Nankai Trough within the subsequent 30 years.
A 559-mile lengthy fault line positioned off Japan’s Pacific coast characterised by its subduction, during which one tectonic plate is compelled beneath one other, the Nankai Trough has produced devastating earthquakes each 90 to 200 years. The final one occurred in 1946.
Underneath the federal government’s worst-case state of affairs, the following Nankai megathrust earthquake is projected to kill about 300,000 individuals — most of them more likely to perish within the tsunamis reaching as excessive as 100 ft — and trigger as much as $1.8 trillion in injury.
By comparability, the dying toll for the 1989 Loma Prieta earthquake and the 1994 Northridge earthquake — the 2 largest seismic occasions in current California historical past — was 63 and 57. Within the meantime, specialists are learning the southernmost tip of the San Andreas fault, which hasn’t had an earthquake of 7 or bigger since someday between 1721 and 1731.
“A future nice Nankai earthquake is definitely probably the most long-anticipated earthquake in historical past — it’s the unique definition of the ‘Massive One’,” wrote geologists Kyle Bradley and Judith A. Hubbard in 2024.
Earlier this month, the Japanese authorities introduced a collection of countermeasures geared toward lowering the variety of deaths by as much as 80% and structural injury by 50%, together with making buildings extra earthquake-resistant and enhancing evacuation protocols.
“It’s vital for the nation, municipalities, corporations and nonprofits to return collectively and take measures to be able to save as many lives as potential,” Japanese Prime Minister Shigeru Ishiba stated.
However Nishimura, the earthquake professional, says that extra must be finished to satisfy these formidable targets.
“Though realizing the lower in structural injury could also be difficult because of a restricted price range, lowering fatalities may be achieved by extra soft-type countermeasures, equivalent to coaching and evacuation drills,” he stated.
