Japan lifts advisory after strong 6.7-mangitude tremor

A 6.7-magnitude earthquake struck off the country’s northern Pacific coast, prompting a tsunami advisory from Japan's weather authorities.

According to the BBC, the earthquake caused small tsunami waves, resulting in no potential damage.

Concerning the tragic incident, more than 6,000 people were evacuated along the coast of Aomori Prefecture, the northernmost province of Japan’s main island.

A 7.5 quake in the same region injured at least 50 people.

Authorities have issued warnings of the probability of a future earthquake. Japan has been bracing for a big one-in-a-century quake.

These megathrust earthquakes are prone to hit every hundred years or, as is often the case in pairs: the last pair struck in 1944 and 1946.

According to Japan’s earthquake investigation panel, there was a 60-90% chance that a megaquake would occur in the Nankai Trough-an area of seismic activity which serves as the rocky stretch along Japan’s Pacific coast-within the next three decades.

Japan’s prime minister Sanae Takaichi was of the view that the quake does not fall under the megaquake advisory, but authorities had warned that a stronger tremor could occur after a magnitude 7.5 earthquake struck northeastern Japan on Monday.

The tsunami advisory was issued after waves were observed at one metre (3.3ft). Residents are advised to stay away from the water and coastal years.

According to the JMA, the next on the scale is a major tsunami warning, and waves anticipated to be more than 3m.

In addition, the government announced a special alert across a wide area, from Hokkaido in the north to Chiba, east of Tokyo, signaling an increased possibility of a powerful earthquake hitting again within a week.
