What is a significant geological hazard associated with the Ring of Fire?

1. Earthquakes

2. Tsunamis

3. Volcanic eruptions

4. All of the above

The correct answer is: All of the above

The Ring of Fire is a horseshoe-shaped zone in the Pacific Ocean basin known for its high levels of seismic and volcanic activity. This region is characterized by a large number of active volcanoes and frequent earthquakes, both of which can trigger secondary hazards like tsunamis. Earthquakes occur regularly in this area due to the movement of tectonic plates along the numerous subduction zones, transform faults, and volcanic arcs present. The intense tectonic activity leads to the formation of faults and eventually results in earthquakes. Volcanic eruptions are another hallmark of the Ring of Fire. The subduction of tectonic plates leads to melting of the mantle and formation of magma, which can rise to the surface and result in explosive eruptions. Many of the world's most famous volcanoes, like Mount St. Helens and Mount Fuji, are located in this highly active zone. Additionally, both earthquakes and underwater volcanic eruptions can generate tsunamis, which may pose significant threats to coastal regions. This interconnectedness of geological hazards makes the Ring of Fire a site of major geological concern. Given these facts, it is accurate to state that all three hazards—earthquakes, tsunamis, and volcanic eruptions—are significant geological hazards associated with
