Figure 2: Strong motion attenuation curves.

From: Prediction of ground motion and dynamic stress change in Baekdusan (Changbaishan) volcano caused by a North Korean nuclear explosion

Figure 2

(a) An example of the observed horizontal PGVs of an ML 4.8 earthquake and their fitted attenuation curve. (b) Difference between the observed and predicted horizontal PGVs, suggesting good representation of observed PGVs with the PGV attenuation curves. (c) Determined event-strength-calibration constants for PGA and PGV attenuation curves for North Korean UNEs as a function of magnitude, presenting strong linear relationships.
