The strongest temblor, officially named the 2024 Noto Peninsula Earthquake, is classified as a reverse fault earthquake with a preliminary magnitude of 7.6 by a government panel, and intermittent aftershocks are hampering recovery support to the affected areas.

Striking at a shallow depth centered around 30 km east-northeast of Wajima, the devastating quake on New Year's Day registered a maximum intensity of 7, with tremors felt in large metropolises such as Tokyo and Osaka.
