Canary Islands - October 13th, 2011

Underwater eruptions from the El Hierro volcano, which commenced on Monday, are continuing a few kilometres off the town of La Restinga, the southernmost town in The Canary Islands. The estimated 670 residents of the town have been evacuated from their homes. Hierro, a shield volcano, has had a single historic eruption from the Volcan de Lomo Negro vent in 1793.

In this image a large green stain is visible on the surface of Las Calmas Sea (lower left corner). The large stain is emanating from two fissures on the sea bed, approximately 700-1000 metres below the surface.

The eruptions take place amidst an unprecedented number of earthquakes in El Hierro. The number of earthquakes recorded since July 17, 2011 on El Hierro has now exceeded 10,500. However, the number and intensity of earthquakes has reduced signifcantly in the past 48 hours.

Dust sweeps southwestward, blowing off the coast of Morocco and Western Sahara (right) and over the Canary Islands in the Atlantic Ocean.

The archipelago is located just off the northwest coast of mainland Africa, 100 km west of the disputed border between Morocco and the Western Sahara.

All of the Canary Islands are visible in the main image: (from highest to lowest) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, El Hierro, Alegranza, La Graciosa and Montaña Clara.

The close-up focuses on, from left to right, La Gomera, Tenerife and Gran Canaria. Clouds flank the northern sides of their respective volcanic peaks.

La Palma, Canary Islands - August 1st, 2009

A forest fire fanned by high winds has forced the evacuation of about 4,000 residents on the Canary Island of La Palma, off the West African coast, the Spanish government said Saturday.

Flames raging on steep hillsides southeast of the island’s dormant San Antonio volcano have engulfed several houses and could damage wildlife habitats reported an environmental worker.

A plume of smoke rose from the island to an estimated height of more than 1,000 meters (3,300 feet). Here, the plume can be seen blowing to the southeast off the southern tip of La Palma. A smaller fire has been controlled on La Gomera, 30 kilometers (18 miles) southeast of La Palma, visible in the center of the image.

The islands of Tenerife (right) and El Hierro (bottom left) are also visible. Some smoke hangs in the air north of El Hierro, while the northern side of La Gomera is flanked by rippled wave-clouds.

The cause of the fire on La Palma is unknown. Several days of high temperatures have contributed to dry conditions on the normally verdant La Palma – one of the least developed and greenest of Spain’s Canary Islands.

Virtually all the island’s firefighting forces, including several aircraft, have been deployed to combat the blaze at three points around the town of Fuencaliente.

The Canary Islands, Spain

Isla de La Palma (known in English as “La Palma”), is one of the seven major Canary Islands (Spain) in the Atlantic Ocean off of the west coast of Africa.

La Palma, like the other islands of the Canary Island archipelago, is a volcanic ocean island. The volcano rises almost 7 km above the floor of the Atlantic Ocean.

Proportional to its size, it is alleged to be the steepest island in the world. The highest peaks reach over 2400 m above sea level, and the base of the island is located almost 4000 m below sea level.

The northern part of La Palma is dominated by the Caldera de Taburiente, clearly visible in the center of the island, with a width of 9 km and a depth of 1500 m. It is surrounded by a ring of mountains ranging from 1600 m to 2400 m in height.

Only the deep Barranco de las Angustias (“Valley of Fear”) canyon leads into the inner area of the caldera. The outer slopes are cut by numerous gorges, which appear as black and white lines, running from 2000 m down to the sea.

Like the rest of the chain, the island is sharply mountainous. It has an area of 278 km². The highest point is situated in the middle of the island, in Malpaso, 1501 meters high.

Upon opening the full image, two other islands are visible: El Hierro (bottom) and part of La Gomera (right).

Like the rest of the chain, El Hierro island is sharply mountainous. It has an area of 278 km². The highest point is situated in the middle of the island, in Malpaso, 1501 meters high.

La Gomera is the second-smallest of Spain’s Canary Islands. The island is of volcanic origin and roughly circular; it is about 22 km (15 miles) in diameter and rises to 1487 m (nearly 5000 feet) at the island’s highest peak, Garajonay.

The central mountains catch the moisture from the trade wind clouds and yield a dense jungle climate in the cooler air, which contrasts with the warmer, sun-baked cliffs near sea level. Between these extremes one finds a fascinating gamut of microclimates.
