Earthquakes can’t be predicted. But a manga artist’s dream of a July 5 'megaquake' has spooked some residents and travelers.

More than 900 earthquakes have shaken a remote and sparsely populated island chain in southern Japan over two weeks, leaving the residents shocked. However, authorities in Japan have warned of more possible strong earthquakes.

The viral rumours have created panic among tourists, with some airlines cancelling flights to Japanese cities due to low passenger demand.
