Geography & Environment in Nauru
Geography & Environment
Nauru’s physical geography is unusually compact: a narrow coastal strip surrounds a raised coral-limestone plateau with no permanent river network.
Nauru at a Glance
Nauru’s physical geography is unusually compact: a narrow coastal strip surrounds a raised coral-limestone plateau with no permanent river network.
Physical geography
Nauru is a small raised coral island with a narrow low coastal belt surrounding an elevated limestone plateau in the interior. The relief focus used here is Raised coral plateau and narrow coastal belt, presented as a regional physical reference.
The climate is tropical maritime, hot and humid throughout the year, with rainfall that is highly variable from year to year.
There are no permanent rivers; rainfall collects in small depressions or infiltrates the limestone, and groundwater resources are limited and vulnerable to salinity.
