Study Notes
Pacific Ring of Fire
- A major volcanic zone encircling the Pacific Ocean, extending from Chile to Alaska.
- Cuts through key regions: Andes Mountains, Central America, Mexico, California, Cascade Mountains, and Aleutian Islands.
- Continues down Asia's east coast from Siberia to New Zealand, passing through Kamchatka, Kurile Islands, Japan, Philippines, Celebes, New Guinea, Solomon Islands, and New Caledonia.
Global Distribution of Volcanoes
- Approximately 1,500 active volcanoes worldwide.
- The Philippines is home to a significant number of these volcanic formations.
Volcanoes in the Philippines
- Luzon Volcanic Arc: A chain of subduction-related volcanoes located on the western side of Luzon Island, including notable volcanoes like Mount Pinatubo.
- Red triangles on maps indicate volcanoes that have been active within the last 10,000 years.
Active and Inactive Volcanoes by Region
- Luzon: 12 active and 141 inactive volcanoes.
- Visayas: 3 active and 39 inactive volcanoes.
- Mindanao: 8 active and 172 inactive volcanoes.
- Total in Philippines: 23 active and 352 inactive volcanoes, summing to 375 volcanoes.
