Which seismic belt is termed as "Ring of Fire"?

The correct answer is Circum-Pacific belt.

Key Points

• The Circum-Pacific belt, also known as the "Ring of Fire," is an area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
• It is shaped like a horseshoe and spans approximately 40,000 kilometers (25,000 miles).
• This seismic belt is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements.
• The Ring of Fire is home to about 75% of the world's active and dormant volcanoes, and nearly 90% of the world’s earthquakes occur in this region.
• Countries along the Ring of Fire include the United States, Canada, Japan, Russia, the Philippines, Indonesia, New Zealand, and several countries in South America.

Additional Information

• Seismic Activity: This refers to the frequency, type, and size of earthquakes experienced over a period in a specific area. The Ring of Fire is characterized by high seismic activity.
• Plate Tectonics: The movement of large plates of the Earth's crust is responsible for the formation of many geological features, including the earthquakes and volcanoes around the Ring of Fire.
• Oceanic Trenches: Deep underwater valleys formed by the subduction of one tectonic plate under another. The Mariana Trench is the world's deepest oceanic trench and part of the Ring of Fire.
• Volcanic Arcs: Chains of volcanoes that form above a subducting plate, positioned in an arc shape as seen in the Pacific Ring of Fire.
• Subduction Zones: Areas where one tectonic plate moves under another, leading to high volcanic and earthquake activity, common in the Ring of Fire.
