A strong earthquake with a magnitude of 6.2 shook northern Japan early Monday. The quake was felt in parts of Hokkaido, but luckily no damage or injuries were reported. According to the Japan Meteorological Agency, there was no tsunami warning after the earthquake. This means there was no immediate danger from large sea waves. The earthquake happened about 18 kilometers west of a small town called Sarabetsu. It occurred deep underground, which can sometimes reduce damage on the surface. The United States Geological Survey measured the quake slightly lower at 6.1 magnitude. Just a week earlier, Japan experienced a much stronger offshore earthquake, which raised concerns about a possible bigger quake. However, officials said this recent earthquake is not connected to that risk, and there is no increased danger at this time.
