A powerful magnitude 7.5 quake off Japan's northern coast triggered tsunami waves on December 8, but a clip circulating in Malay-language posts about the intensity of the tremor does not show its impact.

Another 6.7-magnitude earthquake hit Japan on Friday (December 12), just days after a powerful 7.5-magnitude quake struck the same region and left at least 50 people injured.

The agency has issued a tsunami advisory for parts of Japan's eastern coast, warning that the waves could reach up to one metre (3.3ft).
