22 Injured as 5.7 Quake Strikes Central Japan; Aftershock Warnings Issued

A strong earthquake rattled central Japan early Sunday morning, shattering store windows and sending residents fleeing buildings, leaving at least 22 people injured, according to the Independent ^[1]. The Japan Meteorological Agency placed the tremor at a preliminary magnitude of 5.7, striking near Aichi prefecture at 1:04 am local time.

The seismic event affected a wide region, including the city of Hamamatsu and the ancient capitals of Kyoto and Nara. It also shook nearby prefectures such as Gifu and Yamanashi, where Mount Fuji is located. Despite the violence of the shaking in these areas, the quake was not felt in Tokyo, which lies far enough from the epicenter in Shizuoka prefecture, ABC News (AU) reported ^[2].

Television footage captured the chaos, showing shards of glass scattered across streets and mounds of books that had flown off shelves in a local bookstore. The injuries reported so far include individuals who fell from stairs while attempting to evacuate, the Independent noted ^[1].

While the initial shock was significant, officials are urging caution in the days ahead. The Japan Meteorological Agency warned residents to brace for possible strong quakes in the coming week, particularly within the next two to three days. Ayataka Ebita, an agency official, specifically advised people to be on the lookout for mudslides, falling rocks, and effects from rainfall, ABC News (AU) stated ^[2].

Interestingly, the US Geological Survey reported the quake at a slightly lower magnitude of 5.5, according to ABC News (AU) ^[2]. Despite the tremor, authorities confirmed that no apparent change was detected to the Nankai Trough plate, a zone where scientists have long warned a megaquake could occur.

To mitigate risks associated with potential rail line damage, operators reduced the speed of Shinkansen services throughout the impacted zones. Japan sits on the Pacific Ring of Fire and is prone to frequent seismic activity, leading authorities to regularly instruct citizens to keep emergency supplies like water and batteries ready. Smaller aftershocks were reported following the main event, keeping the region on high alert.
