Territory of Guam
August 14, 2025 - The capital, Hagåtña (formerly Agana), is located on the west coast, near the middle of the island, and is the seat of government and the site of the main commercial districts on Guam [10]. The northern part of the island is a forested coralline limestone plateau with sheer coastal cliffs, while the south contains volcanic peaks covered in forest and grassland. A coral reef surrounds most of the island, except in areas where bays exist that provide access to small rivers and streams that run down from the hills into the Pacific Ocean and Philippine Sea [1, 9]. The Northern Guam Lens provides nearly 40 million gallons per day of drinking water (about 80 percent of the total) to the island of Guam [8]. Guam is the closest landmass to the Mariana Trench, the deepest point in the ocean [9]. Because of its strategic location in the western North Pacific Ocean, the U.S.

To the south and southeast of Guam is the Mariana Trench, which has its deepest expression within the Guam EEZ—in fact, this is the deepest location in the global ocean. The trench is partly filled with sediment. East of the Mariana Trench is the sediment-covered Pacific Ocean abyssal plain with several large Cretaceous (>65 million years old) seamounts that protrude through the sediment. The underlying crust in this area is Jurassic in age (>142 million years old) and is the oldest part of the Pacific Ocean crust.
