Pacific ring of fire eruption

Tonga, a 170-island archipelago about halfway between Australia and Tahiti, is part of the Pacific "ring of fire" — an arc of earthquake and volcanic zones stretching from Chile in South America through Alaska and down through Vanuatu to Tonga.The volcano began erupting on Monday and ejected so much lava that by Wednesday it had formed the island about seven miles off the coast of Tongatapu, the main island of Tonga.
