What Happened

A magnitude 6.0 earthquake struck Japan's northern island of Hokkaido on Sunday evening, just hours after a 5.9-magnitude quake hit the Tokyo region and nearby prefectures. The earlier quake injured more than 40 people, disrupted train services, and caused localized infrastructure damage, including a ruptured water pipe in Tokyo. Authorities said the Hokkaido quake did not trigger a tsunami warning.

Key Takeaways

The back-to-back tremors underscore Japan's vulnerability to seismic activity. While the latest quake caused no immediate tsunami threat, officials have warned of possible aftershocks and similar earthquakes in the coming days, keeping emergency services on alert.
