La Palma is located in Spain. Its cordnents are 28.58 N, 17.83 W. Its summit elevation is 2,246 m.

La Palma has seven historic eruptions, the most recent in 1971 from the Teneguia vent. Other vents formed in historic time include Tahuya, a cone of lapilli, scoria and bombs about 3,000 feet tall (1,000 m) tall that formed over a three month period in 1585 by Strombolian eruptions and San Martin, a cone and crater that formed over two and a half months in 1646.

La Palma is a stratovolcano, and is the largest of the Canary Islands. A stratovolcano is a volcano composed of lava and ash deposited in alternating conical layers. La Palma is a wedge-shaped volcano.
5
La Palma does not really have damage effect because it only erupts about every 20 years.
6
La Palma stretches 21,320 ft above the surrounding ocean floor. Two main rock layers separated by a line about 1400 feet above sea level make up La Palma. The lower layer is made of pillow lavas cut by basaltic dikes. The thickness of the pillow lavas range from 33 to 1150 ft. Most of the dikes are located within 2 miles of the west coast. The upper layer consists of basaltic lavas and pyroclastic rocks. Small alkalic domes have pushed their way into this area.

La Palma lies in both the cool north-easterly Canary current and the north-easterly trade winds, giving it a sunny climate with year-round moderate temperatures, rather cooler than would be expected given the latitude of the island. Rainfall levels vary substantially across the island. The prevailing north-easterly trade winds bring moisture down to the Canaries, and the high altitude of the island means that most of this is deposited to the north-east. The southern part of the island is relatively dry and sunny. This gives rise to dramatic differences in vegetation.

La Palma is active the last eruption was in 1971.
