Fig. 3From: Strong ground motion simulation of the 2016 Kumamoto earthquake of April 16 using multiple point sourcesComparison of phase characteristics between the mainshock and a small earthquake. A band-pass filter (0.2–2 Hz) is applied. The phase characteristics of the red lines are from the earthquake that occurred on April 16, 2016, at 04:51 (JST) with MJMA4.3. Variance reduction (VR) is calculated using a section of 10 s starting from the arrival of S-waveBack to article page
