Fig. 14From: Seismic signature detection during the 2018 Anak Krakatau flank collapse and tsunami using seismic amplitudes from regional-scale monitoringTime evolution of radar reflectivity factor over Anak Krakatau. a Illustration of the radar scanning planes at various elevation angles (blue lines). Only elevation angles of > 0.5° are used. Red-shaded rectangle represents the vertical area examined in b. b Vertical (upper panel, facing north) and horizontal (bottom panel) distributions of maximum reflectivity factors at each radar observation. White areas denote no radar data. White lines denote the outline of Anak Krakatau and the surrounding islandsBack to article page
