The Pacific Ring of Fire
The towering volcanoes of Costa Rica, known as stratovolcanoes, are amongst a special group that circles the globe. They are part of the ‘Pacific Ring of Fire’, which encircles the Pacific Ocean, sitting on the edge of the Pacific Tectonic Plate. Along this plate are located most of the active or dormant volcanoes on earth (about 75%). The region also produces the highest incidences of earthquakes and volcanic activity on earth. This ring runs through Chile, Peru, Ecuador, Panama, Paraguay, Columbia, El Salvador, Costa Rica, Mexico, Guatemala, USA, Canada, Russia, Philippines, Tonga, and New Zealand. Amazingly, there are over 120 volcanic sites in Costa Rica alone. Of that number, six are active volcanoes and 61-are dormant. The balance of them is believed to be extinct. Five of the six active volcanoes in Costa Rica are over 6,000 feet high.
Volcanoes exist in three states; active, dormant, or inactive.
The six active volcanoes in Costa Rica are:
Rincón de la Vieja Volcano 6,385 ft (1,916 m)
Arenal Volcano 5,437 ft (1,657 m)
Poás Volcano 8,845 ft (2,708 m)
Irazú Volcano 11,260 ft (3,432 m)
Tenorio Volcano 6,286 ft (1,916 m)
Turrialba Volcano 10,919 ft (3,328 m)
