Seismologists often use the surface‐wave magnitude Ms (Gutenberg, 1945) to estimate the size of an earthquake and as basis for different types of seismological studies. Those include, among others, earthquake catalogs (e.g., Abe, 1981; Pacheco and Sykes, 1992), magnitude conversion relationships (e.g., Ekström and Dziewonski, 1988; Scordilis, 2006), and tsunami earthquakes (Kanamori, 1972; Jia et al., 2022).

The computation of Ms is relatively simple because it is based on the measurement of the amplitude and period of surface waves generated by shallow earthquakes (usually considered as such if...
