Two earthquakes rattled Japan on Wednesday, just days after the anniversary of 2011’s tragic tsunami. First, a 6.8 temblor struck northern Japan. Several towns were evacuated, and forecasters issued a tsunami warning that was later lifted. Later, a shallow 6.1-magnitude quake struck near Tokyo. No damages or injuries have been reported from either incident. Last year’s earthquake, a 9.0 that hit roughly the same area as today’s first earthquake, triggered a massive tsunami that left 19,000 dead.
