Guam [SEP] Geography
Due to its location on the Mariana Plate just westward of where the Pacific Plate subducts the Mariana and the Philippine Sea Plates, Guam occasionally experiences earthquakes. In recent years, most with epicenters near Guam have had magnitudes ranging from 5.0 to 8.7. Unlike Anatahan in the Northern Mariana Islands, Guam is not volcanically active, though vog (volcanic smog) from Anatahan affects it due to proximity. A coral table reef surrounds most of Guam, and the limestone plateau provides the source for most of the island's fresh water. Steep coastal cliffs dominate the north, while mountains inform the topography of the island's southern end; lower hills typify the area in between.
