Massive landslides can generate significant tsunamis and endanger coastal communities, as shown by recent catastrophic events such as the 2018 Palu Tsunami and 2018 Sunda Strait Tsunami (e.g., Heidarzadeh et al. 2018; Takabatake et al. 2019). While a number of experimental studies have been conducted to investigate landslide generated tsunamis, most were performed using two dimensional (2D) wave flumes (e.g., Fritz et al. 2004; Takabatake et al. 2020). Thus, the present study conducted three-dimensional (3D) experiments to clarify the characteristics of landslide-generated tsunamis, and to develop empirical equations that can predict the generated wave heights and periods.
