Japan's earthquake assessment panel says the tremor that shook Aichi did not change how the tectonic plates beneath the region are locked together, despite its revised epicenter falling within the anticipated Nankai Trough earthquake zone.

Japan's TBS NEWS DIG Powered by JNN, the news service of Tokyo Broadcasting System and the Japan News Network, shows committee chairman Hirata explaining that conclusion at a press conference. The report says experts observed no significant plate changes that would indicate an increased likelihood of a megaquake.

The Japan Meteorological Agency relocated the earthquake's epicenter from western Shizuoka Prefecture to eastern Aichi Prefecture. The quake struck around 1:04 a.m. and produced shaking rated upper 5 in Chita, a city in central Japan. That is a measure of shaking at a particular location, not the earthquake's magnitude.

Footage includes views of Nagoya Station and Chubu Centrair International Airport, followed by shattered windows and toppled stone lanterns at a shrine.

The Nankai Trough marks a plate boundary beneath the sea off southwestern Japan. The committee's conclusion concerns whether this earthquake changed that wider threat: it found no evidence of an increase, rather than declaring the region free of earthquake risk.
