Which one of the following regions has the largest number of active volcanoes?

The correct answer is Aleutian Islands.

Key Points

• The Aleutian Islands are located in the Northern Pacific Ocean, stretching from Alaska to Russia.
• They are part of the Pacific Ring of Fire, which is known for its high volcanic activity.
• The region hosts over 80 active volcanoes, making it one of the most volcanically active areas in the world.
• Due to tectonic plate interactions (North American Plate and Pacific Plate), frequent volcanic eruptions occur in the Aleutian Islands.

Additional Information

• Alaska: Alaska is home to many active volcanoes, primarily along the Alaska Peninsula and Aleutian Arc. However, the Aleutian Islands specifically have the highest concentration of volcanic activity.
• Hawaii Islands: Hawaii is famous for its shield volcanoes, such as Mauna Loa and Kilauea. While volcanic activity is significant, the number of active volcanoes is fewer compared to the Aleutian Islands.
• Iceland: Iceland is located on the Mid-Atlantic Ridge and is volcanically active due to tectonic plate divergence. It has several notable volcanoes, such as Eyjafjallajökull, but the overall number of active volcanoes is lower than the Aleutian Islands.
