Claim: The Ring of Fire is an area where small-to-moderate explosive eruptions have been recorded with its largest volcanic eruption happened in Lascar, Chile in 1993.
Evidence: The Ring of Fire (also known as the Rim of Fire or the Circum-Pacific belt) is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur. Frequent small-to-moderate explosive eruptions have been recorded from Lascar in historical time since the mid-19th century, along with periodic larger eruptions that produced ash and tephra fall up to hundreds of kilometers away from the volcano. The largest eruption of Lascar in recent history took place in 1993, producing pyroclastic flows as far as 8.5 km (5 mi) northwest of the summit and ash fall in Buenos Aires, Argentina, more than 1,600 km (994 mi) to the southeast.
