Piton Montvert

Fournaise, Piton de la

Shield volcano · France · 2632m

The massive Piton de la Fournaise on the island of Réunion is one of the world's most active volcanoes. It is seen here in 1977 with a black lava flow descending the outer NE flank to the sea. The unvegetated summit (top left) was constructed within an 8-km-wide caldera that is breached to the sea. Its sloping N rim is marked by the diagonal vegetation line at the left. More than 150 eruptions have occurred since the 17th century, mostly from vents within the caldera.

Geological summary

Piton de la Fournaise is a massive basaltic shield volcano on the French island of Réunion in the western Indian Ocean. Much of its more than 530,000-year history overlapped with eruptions of the deeply dissected Piton des Neiges shield volcano to the NW. Three scarps formed at about 250,000, 65,000, and less than 5,000 years ago by progressive eastward slumping, leaving large embayments open to the E and SE. Numerous pyroclastic cones are present on the floor of the scarps and their outer flanks. Most recorded eruptions have originated from the summit and flanks of Dolomieu, a 400-m-high lava shield that has grown within the youngest scarp, which is about 9 km wide and about 13 km from the western wall to the ocean on the E. More than 150 eruptions, most of which have produced fluid basaltic lava flows, have occurred since the 17th century. Eruptions in 1708, 1774, 1776, 1800, 1977, and 1986 originated from fissures outside the scarps.

From Wikipedia

Piton de la Fournaise is a shield volcano on the eastern side of Réunion island, a French overseas department and region, in the Indian Ocean. It is currently one of the most active volcanoes in the world, along with Kīlauea in the Hawaiian Islands, Stromboli and Etna in Italy and Mount Erebus in Antarctica. A previous eruption began in August 2006 and ended in January 2007. The volcano erupted again in February 2007, on 21 September 2008, on 9 December 2010, which lasted for two days, and on 1 August 2015. The volcano is located within Réunion National Park, a World Heritage Site.
