Correction: Hayakawa et al. Lithosphere–Atmosphere–Ionosphere Coupling Effects Based on Multiparameter Precursor Observations for February–March 2021 Earthquakes (M~7) in the Offshore of Tohoku Area of Japan. Geosciences 2021, 11, 481

The authors would like to make the following corrections to this paper [1]:

1. Change in Equation

In the original article, the local EQ magnitude M in Equation (1) was wrongly written as M_L. The correct equation should be:

$$K_{LS}=\frac{{10}^{0.75M}}{10(R+100)}$$

(1)

where R is the distance from the observation station to the EQ epicenter (in km) and M is the local EQ magnitude.

2. Changes in Main Body Paragraphs

We have found two inadvertent errors in our paper published in Geosciences [1].

In the original article, there was a mistake in the first paragraph of Section 3.1 (ULF/ELF Data). One-second sampling ULF data were actually observed by the fluxgate magnetometer but not by the induction magnetometer. In addition, only two magnetic field components (H and Z) were analyzed in this research; it was wrongly stated in the original article that there were three magnetic field components as D was included by mistake. Accordingly, in the second paragraph of Section 3.2.1 (Lithospheric ULF Radiation), “three magnetic field components” should have been “two magnetic field components”.

3. Change in Reference List

In reference [103], the last name of the first author should be “Marchitelli”.

The authors apologize for any inconvenience caused and state that the scientific conclusions remain unaffected. The original article has been updated.
