UPSC CAPF – 2016
1. **It is an active volcanic realm:** Correct. The Ring of Fire contains a vast majority of the world’s active and dormant volcanoes.
2. **It is an active seismic realm:** Correct. It is the most seismically active region globally, experiencing frequent and powerful earthquakes.
3. **It is a divergent plate boundary:** Incorrect. While there are some segments of divergent boundaries (like the East Pacific Rise) and transform boundaries within or connected to the Ring of Fire, the dominant type of plate interaction responsible for the intense volcanism and seismicity in most parts of the belt is **convergent**, involving subduction zones. Divergent boundaries are typically associated with mid-ocean ridges.
4. **It is prone to Tsunami:** Correct. Tsunamis are often triggered by large underwater earthquakes, volcanic eruptions, or landslides, particularly those associated with subduction zones found along convergent plate boundaries like those prevalent in the Ring of Fire.
Therefore, statements 1, 2, and 4 are correct, while statement 3 is incorrect.
