" Ring of Fire " is a term often mentioned in news about earthquakes and volcanic eruptions, especially events occurring in countries around the Pacific Ocean, from Japan, Indonesia, New Zealand to the west coast of the Americas. What exactly is this area, why do natural disasters happen frequently there, and which countries lie along the Ring of Fire?
The Ring of Fire or Ring of Fire is a curved chain of volcanoes and ocean trenches surrounding parts of the Pacific Ocean basin. It resembles a ring or horseshoe shape, which is how it got its name.
The U.S. Geological Survey (USGS) states that this region experiences frequent earthquakes and volcanic eruptions. The ocean trenches are located on the outer edge, while volcanic island arcs run parallel to the trenches, closer to the continental side.
However, the term " ring " does not mean the volcanoes form a perfect circle but refers collectively to a series of ocean trenches and volcanic chains arranged around the Pacific Ocean.
The Ring of Fire consists of many ocean trenches and volcano chains related to tectonic plate movements and interactions. When plates converge, one may subduct beneath another, creating deep ocean trenches, earthquakes, and volcanic activity. This explains why the Pacific region often experiences continuous geological phenomena, especially earthquakes and volcanic eruptions.
The Ring of Fire stretches around the Pacific Ocean, from Oceania and Asia northward before curving down along the western coasts of the Americas. Key countries and territories on or near this zone include:
Note that this list describes general areas shown on maps and does not imply equal risk throughout these countries, as trench locations, volcanic arcs, and distances from tectonic boundaries vary.
The main Ring of Fire zone in Southeast Asia passes through Indonesia and the Philippines Therefore, Thailand is not directly on the Ring of Fire. However, large nearby earthquakes can cause tremors or effects in Thailand, though typically less severe than in countries on the ring itself.
Countries located on the Ring of Fire may experience geological events more often than many other parts of the world, but this does not mean constant severe earthquakes or volcanic eruptions.
Each country must rely on earthquake and volcano monitoring, appropriate building design for risk levels, and effective warning and evacuation plans for residents.
