Palau at a Glance
Palau’s island chain combines volcanic uplands, dramatic limestone karst, coral islands and extensive reefs within a wet tropical maritime setting.
Physical geography
terrain · drainage · setting
Palau includes high volcanic islands, uplifted limestone islands with steep karst forms, low coral islands and reef systems spread across the western Pacific. The relief focus used here is Volcanic high islands, limestone islands and coral atolls, presented as a regional physical reference.
Regional frameMicronesia
SettingIsland country
Relief focusVolcanic high islands, limestone islands and coral atolls
Climate pattern
The climate is tropical maritime, warm and humid throughout the year with abundant rainfall and relatively small seasonal temperature variation.
Water and landform context
High islands contain streams, wetlands and freshwater lenses, while smaller coral islands rely more heavily on rainfall and shallow groundwater within porous substrates.
