Study reveals precursors to the 2021 Fukushima earthquake through multi-parameter analysis

A new study was conducted to understand the precursors to the 2021 Fukushima Prefecture Offshore Earthquake (Mj = 7.3), which occurred on February 13, 2021, off the coast of Fukushima, Japan, as an aftershock of the 2011 Tōhoku earthquake and tsunami. The investigation, led by Masashi Hayakawa and Yasuhide Hobara, focused on the Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) channels and multi-parameter anomalies that occurred before the earthquake.
