About 90%[2] of the world's earthquakes and 81%[3] of the world's largest earthquakes occur along the Ring of Fire. The next most seismically active region (5–6% of earthquakes and 17% of the world's largest earthquakes) is Alpide belt, which extends from Java to the northern Atlantic Ocean via the Himalayas and southern Europe.[4][5]
All but three of the world's 25 largest volcanic eruptions of the last 11,700 years occurred at volcanoes in the Ring of Fire.[6]
The famous and very active San Andreas Fault zone of California is a transform fault which offsets a portion of the East Pacific Rise under the southwestern United States and Mexico; the motion of the fault generates numerous small earthquakes, at multiple times a day, most of which are too small to be felt.[8][9]
