Use of ground-penetrating radar (GPR) is being common in recent paleotsunami study. A notable advantage of GPR survey is capability for retrieval of plenty of subsurface data, which will benefit to understand paleotopography and sedimentary environment and optimal location for sediment sampling. We can obtain better sediment samples that include as many tsunami deposits as possible, by assessing preservation potential of deposits considering the paleotopography inferred from the GPR data. GPR survey is also useful to know distribution and geometry of tsunami-related erosional features, which provide clues for reconstruction of tsunami history. |
