Piton de la Fournaise
Shield volcano in southeast Réunion, Indian Ocean
Piton de la Fournaise (French: [pitɔ̃ də la fuʁnɛz]; 'Peak of the Furnace') 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 Islan...

Why It Matters
This volcanic event matters because it represents a significant geological process with both environmental and human impacts. The lava reaching the ocean creates new land through rapid cooling and fragmentation, potentially altering coastal geography and marine ecosystems through chemical interactions and temperature changes. For residents of Réunion Island, this affects air quality through volcanic gas emissions and poses potential hazards to infrastructure and tourism. Scientists closely monitor such events to understand volcanic behavior and improve eruption forecasting for populated volcanic regions worldwide.
Context & Background
- Piton de la Fournaise is one of the world's most active volcanoes, with over 150 recorded eruptions since the 17th century
- Réunion Island is a French overseas department in the Indian Ocean, formed by volcanic activity approximately 3 million years ago
- Previous major eruptions in 2007 and 2015-2016 caused significant lava flows that reached the ocean, creating new coastal formations
- The volcano is monitored by the Piton de la Fournaise Volcano Observatory, established in 1979 following destructive eruptions
What Happens Next
Scientists will continue monitoring gas emissions, seismic activity, and lava flow patterns to determine if the eruption is intensifying or waning. The lava-ocean interaction will likely continue for days or weeks, creating 'laze' (lava haze) plumes containing hydrochloric acid and volcanic glass particles that pose respiratory hazards. Authorities may implement temporary restrictions on coastal access and marine activities near the eruption site for safety reasons.
Frequently Asked Questions
While Piton de la Fournaise eruptions are generally effusive rather than explosive, they can threaten infrastructure near lava flow paths. The current ocean entry creates 'laze' plumes containing toxic gases that can affect air quality downwind, particularly for those with respiratory conditions.
This phenomenon provides valuable data about lava-water interactions, including how rapidly new land forms and how volcanic materials affect marine chemistry. Studying these events helps improve hazard forecasting for coastal communities near active volcanoes worldwide.
The volcano typically erupts every 9-15 months, making it one of Earth's most frequently active volcanoes. Most eruptions are relatively mild with lava flows confined to the volcano's uninhabited eastern flank, though some have threatened communities in the past.
Laze (lava haze) forms when molten lava hits seawater, creating steam clouds containing hydrochloric acid and fine volcanic glass particles. These plumes can cause respiratory irritation, eye discomfort, and acid rain downwind, particularly hazardous for people with asthma or other breathing difficulties.
Yes, when lava cools rapidly in seawater, it solidifies into new rocky coastline. However, wave action may erode some of this new material over time. Previous ocean entries at Réunion have added significant permanent land area to the island's southeastern coast.
