As Japan on Friday marks a century since a devastating 7.9 magnitude earthquake hit the Kanto region, which includes Tokyo, grasping the potential devastation of a future major quake in the capital remains as elusive as it was 100 years ago for many.
The disaster, known as the Great Kanto Earthquake, triggered fires that quickly ravaged Tokyo and Yokohama, leaving more than 105,000 dead or missing.
Although Tokyo and its surroundings were rebuilt — and preparedness has drastically improved, especially following the 1995 Great Hanshin Earthquake and the 2011 Great East Japan Earthquake — experts say being on guard for the next disaster remains a challenge.
