Whose observations first identified the Pacific Ring of Fire as a volcanic belt?
Quick Answer
Geologists in the late 19th and early 20th centuries, including Eduard Suess and later plate-tectonics researchers, recognized the Pacific’s great arc of earthquakes and volcanoes. The term “Ring of Fire” became widely used much later.
The Full Story
The Pacific’s belt of frequent earthquakes and volcanoes was recognized by geologists before plate tectonics was fully understood. Eduard Suess and later researchers noted that the Pacific margins form a broad zone of active geology around the ocean. In the 20th century, the pattern was explained as the result of subduction and plate boundaries. Today the Ring of Fire is known as the world’s most active volcanic and seismic region.
