6.7 Magnitude Earthquake Hits Japan, Tsunami Advisory Issued
A big earthquake happened off the coast of northern Japan on Friday, December 12, 2025.
It was measured at 6.7 on the Richter scale.
The weather office said that waves from a possible tsunami could be up to one meter high and reach the northern Pacific coast.
This earthquake happened just a few days after a bigger one, which was 7.5 on the Richter scale, injured at least 50 people.
The weather office also said that another big earthquake could happen in the same area within a week.
Japan is a country that has many earthquakes because it sits on top of four big pieces of the Earth's crust that move around.
The government has warned that a very big earthquake and tsunami could cause a lot of damage and even kill many people.
There are no signs that the nuclear power plants in the area are having any problems.
A 6.7-magnitude earthquake struck off northern Japan on December 12, 2025.
The Japan Meteorological Agency (JMA) issued a tsunami advisory for waves up to one metre (three feet).
The quake occurred 130 kilometres (81 miles) off the city of Kuji in Iwate prefecture.
This earthquake followed a 7.5-magnitude tremor in the same region on December 8, which injured at least 50 people.
The JMA had previously issued a rare special advisory warning of another possible quake of similar or greater size within a week.
