Fig. 5

Source-normalized amplitudes with epicentral distance for the 2018 Anak Krakatau flank collapse and tsunami episode. We compare the amplitudes with a \(C\approx\) − 0.3, b \(C\approx\) 0, and c \(C\approx\) 0.3, from the scanning using stations at < 400 km from Anak Krakatau, whose names are shown in b. Red lines and areas show the average and ± 1 standard deviation of the theoretical surface wave attenuation curves
