What natural disasters occur in the Pacific Ring of Fire?

The Pacific “Ring of Fire” is the most geologically-dynamic region on the planet.  The convergence of numerous minor and major plates creates endless tectonic activity and the string of volcanoes that runs along the “ring’s” 25,000 mile length ensure that the Pacific Rim will remain prone to natural disasters for as long as the planet itself exists.

Home to hundreds of millions of people, the Pacific Rim that encircles the “Ring of Fire” exists in the shadow of impending disaster.  By far the most earthquake-prone region of Earth and the site of numerous major active volcanoes, the people who occupy the villages, towns, and cities along the Rim live with the constant threat of major earthquakes and, less likely but still possible, major volcanic eruptions that can destroy thousands of homes and kill hundreds of people.  There was no more dramatic example of the dangers of natural disasters in and around the “Ring of Fire” than the December 2004 tsunami that swept across the Indian Ocean following a large undersea earthquake – estimated at above 9 on the Richter Scale that measures earthquake magnitudes, with 1 being a very minor tremor and 10 being the maximum level.  The massive wave that struck the shores of Sumatra, Sri Lanka and other regions killed as estimated 230,000 people and left thousands more homeless.

Similarly, a 2011 undersea earthquake that triggered another tsunami that struck northeastern Japan and destroyed a major nuclear reactor in addition to the human toll directly attributable to the quake and tsunami served as yet another unwelcome reminder of the proclivity for countries along the Pacific Rim to suffer from natural disasters. 

Volcanic eruptions are less likely than earthquakes, but they still occur frequently enough and with sufficient intensity that the likelihood of major damage and losses of life is high.  The 1991 eruption of Mount Pinatubu on the island of Luzon in the Philippines was the most recent major eruption in the region, but active volcanoes exist along the entire length of the “Ring of Fire,” and the potential for another major eruption always exists.

The unique geological formations within the Pacific Rim provide all the ingrediants necessary to ensure that natural disasters within that vast region will continue to occur.  When and where is difficult to predict, but they will continue to occur.
