Why this matters

Earthquakes are common in Japan, a seismically active region, but a magnitude 5.9 near a major metropolitan area like Tokyo can cause significant disruption and fear. The concurrent reporting of a separate tremor in Croatia highlights the global prevalence of seismic activity and the immediate local impact of such events.
