Eruption Overview and Key Facts
The Cumbre Vieja volcanic eruption on La Palma began on September 19, 2021, and lasted 85 days until December 13, 2021, making it one of the longest recorded eruptions on the island. The event was monitored by the Instituto Volcanológico de Canarias and the Spanish National Research Council, which provided real-time data on lava flows, sulfur dioxide emissions, and seismic activity.
The eruption produced multiple lava flows that advanced toward the Atlantic Ocean, generating new land and a large lava delta. The total emitted sulfur dioxide was estimated at approximately 1.5 million tonnes by the Copernicus Atmosphere Monitoring Service, with significant short-term air quality impacts across the Canary Islands.
Economic Impact and Damage Costs
Spanish government damage assessments, updated in 2024, placed the total insured losses from the La Palma volcanic eruption 2021 at roughly 1.2 billion euros, with the majority of claims related to destroyed homes, infrastructure, and agricultural land. The government also deployed emergency funds for temporary housing and business support.
The local economy, heavily dependent on tourism and banana exports, faced severe disruptions. The Canary Islands government reported that over 3,000 hectares of farmland were buried under lava, and the port and airport on La Palma were temporarily closed due to ash and gas emissions.
Recovery, Reconstruction, and Funding
Recovery plans focused on rebuilding homes, restoring roads, and clearing volcanic debris. The Spanish central government and the European Union allocated structural funds for long-term reconstruction, with projects prioritized for affected neighborhoods in Los Llanos de Aridane and El Paso.
As of 2024, public data showed that thousands of properties had been assessed, and a significant portion of reconstruction permits had been issued. The process also involved environmental monitoring of the new lava delta and coastal changes, with ongoing updates from the Instituto Español de Oceanografía and the Cabildo de La Palma.
