Strong earthquake rocks central Japan, injuring at least 22

A magnitude 5.7 earthquake struck central Japan early Sunday, causing injuries to at least 22 people and breaking shop windows, according to local media reports. The Japan Meteorological Agency has warned residents to prepare for more strong quakes over the coming week, particularly in the next two to three days. The quake hit at 1:04 a.m. local time, with smaller aftershocks following shortly after.

The shaking spread over a wide area near Aichi Prefecture, reaching cities such as Hamamatsu, as well as Kyoto, Nara, Gifu, and Yamanashi prefectures, which are home to Mount Fuji. The strongest shaking was reported in Chita, Aichi Prefecture. The shaking was recorded as a magnitude 5.7 by the Japan Meteorological Agency, while the US Geological Survey registered it at 5.5.

The earthquake originated about 40 kilometres (25 miles) below the surface in Shizuoka Prefecture, which borders Aichi. Tokyo was not directly affected by the quake. Severe damage was observed, with smashed shop windows and scattered glass along the streets, as well as piles of books from a bookshop that had been thrown from shelves.

At least 22 people sustained injuries, some of whom fell down stairs while trying to evacuate buildings. The meteorological agency has advised people to remain vigilant for potential risks such as mudslides, falling rocks, and the effects of rain, and to be ready for strong aftershocks in the coming days. No significant changes have been detected in the Nankai Trough, an area where scientists predict the potential for a future megaquake.

The Shinkansen bullet trains in the affected regions were operating at reduced speeds as a precaution, as earthquakes can occasionally damage train tracks. Japan is located in an area known for frequent earthquakes, and authorities frequently advise residents to have emergency supplies, such as bottled water, non-perishable food, batteries, and comfortable walking shoes, readily available at home.
