摘要

We evaluated the effects of the great earthquake of December 2004 on 43 inland caves in the Andaman and Nicobar Islands. Data was collected before and after the earthquake. The number and size of fallen rocks within the caves were taken as a measure of physical damage to the caves. Rockfall was greater in caves located above ground (Z = -3.543, P = 0.000) and in larger caves (chi(2) = 18.545, df = 3, P = 0.000), indicating significantly higher damage to these caves. The impact of damage to the microclimate and ecosystem inside the caves is also discussed.
