We weren’t quite done with the Pacific Ring of Fire facts in our last article. In that article, we answered a few question like what it is and why it is so called. We also talked about the countries included in the Pacific Ring of Fire and how big it is. But, we didn’t address these questions:
- Which tectonic plates are in action in Ring of Fire?
- Which are the major volcanic activities and earthquakes related to Ring of Fire?
- What is the alternate name of Ring of Fire?
- What are some weird facts about the Ring of Fire?
In this article, we will try and answer those questions one by one. So, continue reading this list of 20 Ring of Fire facts. Hopefully, you will get some help for your homework.
Ring of Fire Facts: 1-5 | Tectonic Plate Boundaries
1. [highlight]Which tectonic plates are in action in Ring of Fire?[/highlight] There are several. On the eastern side of the Ring of Fire are three plates – South American Plate, Cocos Plate and Nazca Plate. The South American Plate is moving westward while the Cocos Plate and the Nazca Plate are subducted beneath the South American Plate.
2. Towards Central America, there is the Caribbean Plate beneath which, the Cocos Plate is being subducted.
3. On the western side, the Juan de Fuca Plate (which is a small plate) and a part of Pacific Plate are subducting beneath North American Plate.
4. The Pacific Plate, which is moving northwest, is subducting beneath Aleutian Islands Arc in the northern portion of the Ring of Fire.
5. On the farther west of Ring of Fire, the Pacific Plate is also subducting beneath Kamchatka Peninsula arcs on the south of Japan. The southern side of the Ring of Fire is very complex with several small tectonic plates actually colliding with Pacific Plate from New Zealand, Tonga, Bougainville, Philippines and Marina Islands.
Ring of Fire Facts: 6-10 | Major Volcanic Eruptions and Earthquakes of Ring of Fire
6. [highlight]Which are the major volcanic activities and earthquakes related to Ring of Fire?[/highlight] To start with, let us state that most of the active volcanoes in Ring of Fire are on its western edge.
7. The active volcanoes run through Russia’s Kamchatka Peninsula through Japan along with southeast Asia and finally down to New Zealand. One of the [highlight]most active volcanoes in the whole Ring of Fire is New Zealand’s Mount Ruapheu[/highlight]. This volcano gives one major eruption every 50 years and several minor eruptions every single year.
8. [highlight]Indonesia’s Krakatoa is an island volcano with much less eruption frequency that Mount Ruapheu but far more spectacular[/highlight]. A very devastating explosion of Krakatoa in 1883 destroyed the whole island and rocks, volcanic ash and volcanic gases were hurled 50 miles or 80 kilometers straight up in sky. Ever since that eruption, minor eruptions have been taking place and a new island volcano is taking shape. It is known as Anak Krakatoa.
9. [highlight]Another active and devastating volcano on the western side of the Ring of Fire is Mount Fuji[/highlight]. It is Japan’s tallest mountain and it sits at a tri-junction – the meeting place of Philippine Plate, Okhotsk Plate and Amur Plate.
10. The last time Mount Fuji erupted was in 1707 on December 16. The eruption was so powerful and so much of tephra (solid volcanic material – volcanic rocks and volcanic ash) was released that 100 kilometers away in the city of Edo (now Tokyo), candles had to be used right in the middle of the day.
