ABSTRACT
Three sandy beaches on Phuket and Kho Khao islands, Thailand, were monitored annually to study the
short- and long-term impacts of the 2004 tsunami on their meiofauna assemblages and sediment characteristics.
The sediment grain size compositions changed significantly within one year after the tsunami (improved
sorting and less negatively skewed distributions), but meiofauna assemblages did not. The fast recolonization
of the beaches after the tsunami confirmed that meiofauna is highly resilient to ecosystem disturbances. The
tsunami was not observed to have a long-term impact on meiofaunal assemblages.
