A 7.2 magnitude earthquake (revised down from 7.4 by the USGS) in Alaska, USA, late Thursday was the latest in a series of strong earthquakes to hit nations located along the Pacific Ring of Fire during the past week.
Among the other nations to record moderate to strong earthquakes this week include Japan, Fiji, Panama, Papua New Guinea, Indonesia, Costa Rica, Solomon Islands, Vanuatu, Tonga, Samoa, Chile, Peru, Bolivia, Argentina and Antarctica.
The "Ring of Fire" is an arc stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. The Ring of Fire is composed over 75% of the world's active and dormant volcanoes.
