A **magnitude 6.7 earthquake** struck off the coast of **Aomori Prefecture** in 
northeast Japan on Friday, prompting the **Japan Meteorological Agency (JMA)** to
issue a tsunami advisory for coastal communities.

The quake occurred at **11:44 a.m. local time (02:44 GMT)** at a depth of **20 km**,
according to the JMA. The **United States Geological Survey (USGS)** also confirmed
the magnitude at 6.7.

Japan’s **Nuclear Regulation Authority** reported **no immediate abnormalities**
at nuclear facilities in the affected region.

National broadcaster **NHK** noted that the tremors were weaker compared to the **
magnitude 7.5 earthquake** that struck the same region on Monday. That earlier quake
caused significant damage, tearing apart roads, shattering windows, and generating
tsunami waves of up to **70 centimetres**. At least **50 people were injured** in
the incident.

Following Monday’s quake, the JMA issued an uncommon advisory alerting residents
across areas from **Hokkaido to Chiba** to remain vigilant for the possibility of
another strong earthquake within a week.

Japan’s northeast remains deeply affected by the memory of the catastrophic **2011
magnitude 9.0 undersea earthquake**, which triggered a massive tsunami that left**
about 18,500 people dead or missing**.

In 2024, the JMA issued its first special advisory for the southern half of Japan’s
Pacific coastline, warning of a potential **“megaquake”** along the **Nankai Trough**.
Government estimates suggest that a major quake in that zone, followed by a tsunami,
could result in **up to 298,000 deaths** and **$2 trillion in damages**.

Japan, located on the volatile **Pacific “Ring of Fire,”** rests atop four major
tectonic plates, making it one of the most earthquake-prone countries in the world.
