Ternate seismic region where active volcanic activity and frequent earthquakes are common. Ternate belongs to a group of islands that make up the Ring of Fire, known as the Circum-Pacific Belt. Around 90% of the world’s earthquakes and seismic activity occur in this arc in the base of the Pacific Ocean. The region consists almost entirely of an uninterrupted chain of volcanic arcs and oceanic trenches, and experiences continual plate movement. There are 452 volcanoes in the Pacific Ring of Fire, accounting for 75% of the world’s dormant and active volcanoes. Ternate is dominated by the volcanic Mount Gamalama (1715 m).
Circum-Superior Belt Circum-Superior Belt The Circum-Superior Belt is a widespread Paleoproterozoic large igneous province in the Canadian Shield of Northern, Western and Eastern Canada. It extends more than from northeastern Manitoba through northwestern Ontario, southern Nunavut to northern Quebec. Igneous rocks of the Circum-Superior Belt are mafic-ultramafic in composition, deposited in the Labrador Trough near Ungava Bay, the Cape Smith Belt near the southern shore of Hudson Strait and along the eastern shore of Hudson Bay in its northern portion; the Thompson and Fox River belts in the northwest and the Marquette Range Supergroup in its southern portion.
