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.

Since June 21, as many as 1,031 earthquakes rattled the Tokara island chain south of the Kyushu region in Japan.
