18.0N 39.4E

July 20th, 2012 Category: Dust Storms

Red Sea – July 19th, 2012

Fierce winds kick up dust and blow it about, over Sudan, Eritrea, the Red Sea and Saudi Arabia. A thick plume can be seen blowing northeastward off the Sudanse coast, near the border with Egypt, at the upper left. In the lower part of the image, however, the wind direction appears to be blowing the dust northwest, back towards the coasts of Eritrea and Sudan (best observed in full image).

Dust Over the Afar Depression, Ethiopia and Eritrea

12.3N 40.7E

June 10th, 2012 Category: Dust Storms

Ethiopia - June 9th, 2012

Dust blows across the Red Sea and the Bab-el-Mandeb Strait (upper right), over Eritrea (by the coast) and over Ethiopia. In Ethiopia, it is hemmed in and funneled southwards by the mountains bordering the Afar Region. The name of the funnel-shaped area is the Afar Depression or Afar Triangle, a geological depression that is caused by the Afar Triple Junction which is part of the Great Rift Valley. It overlaps Eritrea, Djibouti and the entire Afar Region of Ethiopia. Visible near the left edge, unaffected by the dust, is the green Lake Tana.

Red Sea - April 28th, 2012

Dust hangs in the Red Sea over the Dahlak Archipelago (Ge’ez), an island group located in the Red Sea near Massawa, Eritrea (visible along the shores of the Red Sea in the lower part of the image). The arcipelago consists of two large and 124 small islands. Only four of the islands are permanently inhabited, of which Dahlak Kebir is the largest and most populated. The islands are home to a diverse marine life and sea-birds.

Eritrea and Ethiopia - February 19th, 2010

Eritrea and Ethiopia - February 19th, 2010

This orthorectified image shows part of the Southern Red Sea region of Eritrea, one of the country’s six main regions. It lies along the southern half of the Red Sea, and contains the  major towns of Asseb, Beilul, Rahaita and T’i’o.

The region has an area of around 27,600km², extending over 500km along Red Sea coast but is only around 50km wide. It forms the major part of the Danakil Desert. The highest point in this region is Mount Ramlu (2248 meters).

Upon opening the full image, the Erta Ale Range in Ethiopia is visible to the south. It is the most important axial volcanic chain of the Afar Depression, in Ethiopia’s Afar Region. The range consists mostly of shield volcanoes. The highest volcano of the range is Ale Bagu, at 1,031 m (3,383 ft) high, identifiable by its conical shape towards the bottom center.

Volcanoes and Volcanic Fields in Eritrea and Djibouti – July 12th, 2009

Djibouti and Eritrea - July 2nd, 2009

Djibouti and Eritrea - July 2nd, 2009

The prominent features of this orthorectified ASAR (radar) image of Eritrea and Djibouti include the Mousa Ali Volcano and the Gufa Volcano volcanic field (both in bottom left quadrant) and the Asseb Volcano volcanic field (top right quadrant).

The Mousa Ali Volcano is a stratovolcano located in the Southern Red Sea region on the borders of Eritrea and Djibouti. At 2,028 m (6,654 ft), the volcano is the highest point in Djibouti.

The volcano’s summit is truncated by a caldera, which contains rhyolitic lava domes and lava flows. The last known eruption occurred during the Holocene era.

Northeast of this large volcano is the Gufa Volcano, a volcanic field located in the Southern Red Sea Region of Eritrea near the border with Ethiopia. The peak elevation is 600m, where lava flows are visible. The last eruption of the volcano was inferred to be during the holocene era.

The Asseb Volcano is a volcanic field located in the Southern Red Sea Region of Eritrea. Its peak elevation is 987 m. Like the Mousa Ali Volcano, the most recently identified eruption occurred during the Holocene era.
