The required revision that current physics models use to forecast tsunami hazards is to move away from the classic assumption that great tsunamis are largely non-dispersive waves that travel as a single packet, as the new satellite data shows a complex, dispersive pattern of energy spreading across the ocean. Tsunami forecasting models must now be revised to incorporate dispersive effects and quantify this energy to more accurately predict the wave's timing and force as it approaches the coast.
