We have simulated the tsunami generated from the M 7.5 – 45km NE of Kokopo, Paapua New Guinea (4.081°S 152.569°E, depth=10.0 km, M = 7.5 at 2019-05-14 12:58:26 (UTC) according to USGS. The assumed tsunami sources cover the aftershock area for 2 hours after the mainshock (Fig. 1). The fault size and average slip are 140 km × 15 km and 3.5 m. The focal mechanism is strike=317º, dip=49º, and slip=-26º from the USGS’s W-phase moment tensor solution. The top depth of the fault was assumed to 5 km. The seismic moment is 2.16 x 1020Nm (Mw = 7.5) assuming the rigidity of 5 x 1010N/m2. (see report)
