The eruption of the Teneguía volcano on La Palma in 1971 was a significant geological event in the history of the Canary Islands. This eruption, which began on October 26 and lasted until November 18, was the last terrestrial volcanic eruption in Spain in the 20th century. The Teneguía, located at the southern tip of the island, displayed explosive and effusive activity, producing lava flows that reached the sea, increasing the island's surface area. Although there were no fatalities, the eruption caused material damage to crops and properties. The event attracted international attention, highlighting the active volcanic nature of the islands and underscoring the need for geological studies and emergency plans. The Teneguía eruption is remembered for its impact on local geography and its contribution to scientific and educational tourism in the region.
