Guam
The Mariana chain of which Guam is a part was created by collision of the Pacific and Philippine Sea tectonic plates. Guam is the closest land mass to the Mariana Trench, the deep subduction zone that runs east of the Marianas. 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 Anathan affects it due to proximity.
