Terrain consists of volcanic in origin, surrounded by coral reefs; relatively flat coralline limestone plateau (source of most fresh water) with steep coastal cliffs and narrow coastal plains in north, low-rising hills in center, mountains in south. Elevation extreme haas the lowest point in Pacific Ocean 0 m and highest point in Mount Lamlam 406 m. Natural resources are fishing (largely undeveloped), tourism (especially from Japan).
