Piton de la Fournaise (‘Peak of the Furnace’) Reunion Island Clay Chang and Syman Hossenbux Geology Department Colby College

Geographic and Tectonic Setting Hot spot track extends from India to the island of Reunion Maldives, the Chagos Ridge, the Mascarene Plateau, and the Mauritus Islands The hot spot is presently under the African tectonic plate. Volcanic island of Reunion appeared 3 million years ago

About Piton de la Fournaise Shield volcano From the ocean floor it is over 21,600 feet (6,600 m) tall. The base of the volcano has a diameter of 135 miles (220 km)(the base of Mount St. Helens has a diameter of about 9 km) Two craters, the older Cratere Bory and the active Cratere Dolomieu.

Eruptions Frequent, but short Hawaiian style eruptions lava fountains fast lava flows, low viscosity Na, K, Ca content prevent easy formation of silica chains, result is fast-moving pahoehoe flows

Eruptive History and Hazards one of the most active volcanoes in the world more than 150 eruptions since 17th century active eruption sites are uninhabited, lava flows usually flow into the Indian Ocean Population Within 5 km 55,859 Within 10 km 55,859 Within 30 km 246,792 Within 100 km 717,820

Most Recent Eruption June 21, 2014 eruption on southeastern side of Dolomieu crater warning signs: increased seismicity and gas emissions lava flows https://www.youtube.com/watch?v=DubeBTln934

Volcanic Deposits Different types of Volcanic Ejecta categorised as per their size(Lapilli, Bombs, Ash) Pahoehoe or aa Basaltic rocks Pele’s Hair

Rocks and their composition. Olivine Feldspars Plagioclase Pyroxenes Small minerals rich in Iron and titanium; Magnetite

Tourism World Heritage Site by UNESCO Cite du volcan Museum Island’s main tourist attraction

Monitoring of the Volcano Geophysical sensors tiltmeters extensometers (an instrument used to measure the deformation (length) of a material when it is placed under stress, these changes are usually too small to see with the naked eye) data sent to the Piton de la Fournaise Volcano Observatory
