With over **40,000 kilometers in length**, the **Pacific Ring of Fire** surrounds the coasts of **South America, North America, East Asia, and Oceania**, forming the most active seismic arc on the planet.
According to the **Peruvian Geophysical Institute (IGP)**, this region concentrates:
- **90% of all earthquakes recorded in the world**
- **80% of the most intense earthquakes**
- **75% of the planet’s active volcanoes**
Pacific Ring of Fire: the hidden force beneath the ocean
Below the bed of the **Pacific Ocean**, multiple **tectonic plates** constantly interact. Their **movement, collision, and friction** generate an accumulation of energy which, upon release, causes:
- Earthquakes of great magnitude
- Explosive volcanic eruptions
- Reactivation of dormant volcanoes for centuries
“The intense seismic activity of the Ring of Fire is due to the convergence and friction of tectonic plates,” explained **Hernán Taveras**, executive president of the IGP, in an interview with *BBC Mundo*.
Megathrust Earthquakes: the giants of geology
The so-called **megathrust earthquakes** are the most powerful ones recorded by science. Since the development of the **seismic magnitude scale** in the 20th century, events have been documented that:
- **Shook entire continents**
- **Triggered tsunamis like the one in Sumatra in 2004**
- **Moved mountain ranges and altered the Earth’s geography**
The **United States Geological Survey (USGS)** has listed the **20 largest earthquakes ever recorded**, including one in **Siberia** which, despite its magnitude, caused no casualties.
Volcanoes and Earthquakes: an explosive relationship
Seismic movements can **destabilize volcanic systems**, causing:
- **Sudden eruptions** in active volcanoes
- **Reactivation of dormant craters**
- **Release of accumulated gases and magma**
“It’s like shaking a bottle of carbonated water: a sudden movement can trigger an explosive eruption,” compared **Hugo Delgado**, director of Mexico’s National Center for Disaster Prevention.
Ecological Faults of the Planet
In addition to the Pacific Ring of Fire, there are other faults on the planet that are equally concerning:
**San Andreas Fault (United States):** spans 1,300 kilometers in California and is considered the boundary between the Pacific and North American plates. It is known for having generated some of the worst earthquakes in history.
**Lake Kivu (Africa):** located on the border between Rwanda and the Democratic Republic of the Congo, it is in the Great Rift Valley, generating a large amount of seismic and volcanic activity. In its depths, it holds immense amounts of dissolved carbon dioxide and methane.
**Suswa Fault (Africa):** located in the Great Rift Valley in Kenya. Here, the Earth’s crust splits along long fissures, creating new depressions and causing significant volcanic activity.
