A 6.7 magnitude earthquake hit northern Japan on Friday, prompting temporary tsunami warnings just days after a larger 7.5 tremor injured dozens in the region. Japan's position on the Pacific "Ring of Fire" makes it highly seismically active, experiencing approximately 1,500 earthquakes annually. This recent seismic activity has renewed concerns following the catastrophic 2011 earthquake and tsunami disaster that claimed 18,500 lives.
