Tsunamis and Earthquakes
Cross-sectional views of tsunami deposits at the village of Lampuuk. The larger photo shows that 73 cm of sand was deposited over soil (dark material in bottom center), in beds indicating multiple pulses of sand deposition. The lowermost bed, 45 cm of sand grading upward from coarse to fine, settled from suspension in a single wave and can be used to characterize the wave's height and velocity.
