A rare and alarming seismic swarm has shaken Japan’s southern islands, forcing dozens of residents to leave their homes. Since June 21, more than 1,582 earthquakes in Japan have been recorded in the remote Tokara island region, according to officials. While no major physical damage has been reported. The constant tremors have taken a toll on residents’ mental and emotional well-being.
Akuseki Island, one of the hardest-hit areas, has seen 44 out of its 89 residents evacuate to the mainland hub of Kagoshima. Another 15 people from neighboring islands have also relocated in recent days. The local mayor, Genichiro Kubo, confirmed the information during a press briefing on Monday, July 7, 2025.

The most recent quake, which measured 5.1 in magnitude, struck overnight, further intensifying fears. Although the tremors have not caused any structural collapse, the continuous shaking has disrupted daily life, affected sleep, and raised concerns about what might happen next.
What is Causing the Earthquake Swarm?
Experts believe that an underwater volcano and active magma flows are responsible for the sudden surge in seismic activity. The Japanese Meteorological Agency and seismologists say it is impossible to predict when the quakes will stop. Leaving islanders in a constant state of uncertainty.
Evacuees from Akuseki and surrounding islands are currently being sheltered and monitored. Emergency services remain on high alert, and ferries have been mobilized to aid further evacuations if necessary.
With Japan’s long history of seismic activity, such earthquake swarms are not entirely new. However, the intensity and frequency in such a short period make this event especially unusual.
As the tremors continue, residents and authorities are prioritizing safety while scientists work to better understand the phenomenon beneath the surface.
