Titov and Synolakis developed the MOST model for these entities.
Titov and Synolakis developed the MOST model for these entities. These entities are likely to be formed if there is a sharp upslope at low frequencies on an effective movement-frequency diagram. A distinctive V-shaped formation found on Madagascar indicates that a "mega" one of these entities could have been caused by an ancient meteor impact. That formation is the Fenambosy chevron. Run-up is one measure used to characterize these entities. Due to their long wavelength, they are always shallow-water waves. Drawback, a dramatic drop in sea level, can occur when the trough of these entities reaches the coast first. For 10 points, identify these large waves that can be caused by earthquakes.
