Japan is on high alert as experts warn of a looming once-in-a-century earthquake that could strike at any moment.
The recent 7.1-magnitude quake on 8 August has intensified fears,
prompting a rare nationwide advisory from government bodies that a major
seismic event might occur within the next week. This warning,
unprecedented in Japan's history, has sent shockwaves through a nation
already well-versed in earthquake preparedness.
The potential disaster is linked to the Nankai Trough, a
700-kilometre subduction zone off Japan’s southern coast, where tectonic
plates have historically triggered some of the world’s most powerful
earthquakes.
The last major quakes from this zone occurred in 1944 and 1946, both
registering 8.1 in magnitude and causing widespread devastation. Based
on historical patterns, the Japanese government estimates a 70-80%
chance of a similar event occurring within the next 30 years.
Despite these alarming predictions, there is debate among experts about the accuracy and necessity of such warnings.
Professor Shoichi Yoshioka of Kobe University acknowledges the
significant risk but questions the high probability figures, suggesting
they may be overestimated. Meanwhile, Robert Geller, a seismologist at
the University of Tokyo, argues that focusing so heavily on the Nankai
Trough could lead to complacency in other regions equally prone to
seismic activity.
Japan’s government continues to stress the importance of preparedness, urging citizens and visitors alike to remain vigilant.
While the precise timing of the earthquake is uncertain, the
potential for a catastrophic event has cast a long shadow over the
country, especially as it faces the peak of its summer tourist season.
Travellers are advised to stay informed and take necessary
precautions as Japan braces for what could be a once-in-a-century quake.
