Volcanos In The Caribbean
The Pitons, A Landscape Shaped By Volcanic Activity
The Pitons of St. Lucia are two iconic volcanic spires located on the southwestern coast of the island. These geological formations, known as the Gros Piton and Petit Piton, are significant both geologically and culturally. The Pitons are remnants of a volcanic formation created by the island’s volcanic activity. They are part of the Lesser Antilles volcanic arc, which was formed due to the subduction of the South American Plate beneath the Caribbean Plate. The Petons are classified as remnants of stratovolcanoes, characterized by their steep profiles and layered structure resulting from alternating eruptions of lava flows, ash, and volcanic rocks.
One of the top activities when visiting the Pitons is to hike its almost 23 miles of trails. Guided hikes are available and there’s a wide range of accommodations near the Pitons with prices to fit any budget:
- Ti Kaye Resort & Spa
- Green Fig Resort & Spa
- Sunset Lane
Cultural Importance: The Pitons are a UNESCO World Heritage Site and hold cultural significance for the local population, symbolizing the natural beauty of St. Lucia.
Eco-Exploring and Research
The Pitons are a major hiking destination, offering hiking trails, stunning views, and opportunities for photography and exploration. Researchers study the geology of the Pitons to better understand volcanic processes and the geological history of the Caribbean region.
Recent volcanic activity in Saint Lucia is primarily associated with the Soufrière Volcanic Centre, located in the southwestern part of the island. This area has been the focus of ongoing geological monitoring due to its active nature. The most notable feature here is the Sulphur Springs, which is recognized as the world’s only drive-in volcano and was formed from a collapsed volcanic crater over 410,000 years ago.
Beyond Saint Lucia the Caribbean region is home to numerous additional active volcanoes, primarily located in the Lesser Antilles, where 17 known volcanoes are considered ‘live’ and likely to erupt again across 11 islands. The arc of these volcanos is created by the Lesser Antilles subduction zone, where the oceanic crust of the South American plate is being subducted under the smaller Caribbean plate. This boundary contains these active volcanoes, most notably Soufriere Hills on Montserrat*1; Mount Pelée on Martinique; La Grande Soufrière on Guadeloupe; La Soufrière Saint Vincent on Saint Vincent*2; and the submarine volcano Kick ’em Jenny which lies about 6 miles north of Grenada. Morne Watt on Dominica*3 is an additional volcano that has had recent eruption events.
Montserrat’s Soufrière Hills eruption in 1995
*1- July 1995, Montserrat’s Soufrière Hills volcano, dormant for centuries, erupted and soon buried the island’s capital, Plymouth, in more than 39 feet of mud, destroyed its airport and docking facilities, and rendered the southern part of the island, now termed the exclusion zone, uninhabitable and not safe.
*2 – La Soufrière Volcano on the island of St Vincent which occurred between 27 December 2020 and 22 April 2022.
*3 Dominicas Morne Watt experienced a VEI-1 phreatic eruption in the Valley of Desolation in 1997.
