Fig. 1.From: How precisely can we anticipate seismic intensities? A study of uncertainty of anticipated seismic intensities for the Earthquake Early Warning method in JapanRelation of ac in Eq. (3), JMA instrumental seismic intensity, and 10-degree JMA intensity scale as well as the approximate relation of the JMA intensity scale and Modified Mercalli scale. “L” and “U” on 5 and 6 of the 10-degree JMA scale indicate “lower” and “upper” delineations.Back to article page
