Ninety percent of the world's earthquakes occur in the Ring of Fire, which encircles the basin of the Pacific Ocean.

Armenia Earthquake Memorial Day (2015)

On December 7, 1988, a severe earthquake struck in Armenia, causing catastrophic damage to the entire country's infrastructure and virtually destroying the cities of Spitak, Leninakan (now Gyumri), Kirovakan (now Vanadzor), and Stepanavan. More than 25,000 people were killed in the disaster, with another 140,000 injured and more than one million left homeless, in a disaster zone that measured about 30,000 square kilometers. That day is now remembered each year as a national holiday, marked across the country with prayer, memorial services, and a moment of silence. More...
