SummaryThe effect of branched flow explains how even minute fluctuations in the ocean depth can focus the energy carried by a tsunami wave. A tsunami wave can focus the energy of a seaquake in certain directions where it causes devastating destruction. Current research from the Max Planck Institute for Dynamics and Self-Organization shows that minute fluctuations in the ocean depths can lead to focusing effects and generate strong height fluctuations in the tsunami wave. This formation of a branched flow has severe implications on the way we have to think about predicting tsunamis.
