Doppler velocity of HOK echoes on beam 4 (echo power > 10 dB) versus Japanese Standard Time (JST) after an earthquake on 11 March 2011. Sloped lines mark several individual echo bands propagating northward away from the earthquake epicenter. Measurements at 900–1100 km range (dashed rectangles) are 2-hop signals while their 1-hop counterparts are identified by solid rectangles at 350–500 km range. Adapted from Fig. 5 of Ogawa et al. (2012)
