The Pacific Ring of Fire is a region circling the Pacific where about 90% of world earthquakes and about 75% of active volcanoes concentrate. Comparing major countries along this belt reveals earthquake, tsunami, and volcano risks vary greatly by country.
Japan and Indonesia are the most seismically active countries on the Ring of Fire. Indonesia has the world's most active volcanoes with over 130 active volcanoes. Japan is known for highly developed earthquake-resistant building codes; Indonesia faces challenges in risk assessment and response capacity.
The Philippines also faces high earthquake risk with many active volcanoes. New Zealand also has significant earthquake risk but maintains high national preparedness levels. Chile has experienced the region's largest earthquakes (8.8 in 2010) and has strong earthquake standards.
Mexico also has high earthquake risk with complex geology from multiple magma layers. The western U.S. (California, etc.) is also part of the Ring of Fire with high risk.
