Tsunami radiation pattern

Tsunami radiation pattern for the preferred earthquake parameters shown in inset panel. Note the efficiency of wave propagation toward Delaware Bay and the relative inefficiency of propagation toward the northeast and the west-northwest. Estimated runup (height of tsunami above sea level when it reaches land) at the mouth of Delaware Bay is approximately 50 centimeters (20 inches). Numbers at top of inset panel show preferred earthquake magnitude (7.4) and mean slip (3.5 meters [11 feet]); numbers at bottom show preferred fault length (60 kilometers [40 miles]), width (25 kilometers [15 miles]) and depth to top edge (1 kilometer [0.6 mile]), and strike/dip/rake of assumed rupture plane. Slightly modified from figure 4 of Seismological Research Letters paper.
