Location: Lat. 13.6N, Long. 40.7E
Elevation: 2,011 feet (613 m) Erta Ale is a very remote and rarely visited shield volcano in the Afar region of East Africa. It is Ethiopia's most active volcano and it has been in a state of continuous eruption since 1967. Daytime temperatures will likely be above 40 degrees Celcius and the base of the volcano actually lies below sea level and it's summit rises up to 613 Meters. Erta Ale is known for it's 2 pit craters which have had active lava lakes in the past.
Erta Ale has undergone seven eruption events in the past 125 years. Three of the early eruption dates, 1873, 1903, and 1904 are uncertain. However, 1906, 1940, 1960, and 1967 are well established events. Erta Ale has been erupting continuously since 1967.
Two new studies on Erta Ale have recently been published. Oppenheimer and Francis (1998) looked at the implications of long-lived lava lakes. They believe that Erta Ale's lava lake has been active for at least the last 90 years (making it one of the longest known historic eruptions). Large amounts of heat are released by the volcano but the amount of lava that erupts is relatively small. Oppenheimer and Francis speculated that a higher magma density (caused by the cooling of the lava in the lake) inhibits eruptions. They proposed that most of the magma accumulates in the underlying crust in the form of dikes and sills. Since the Afar region is under extension, conditions are favorable for the injection of dikes and sills.
Barrat and others (1998) looked at the chemistry of the rocks at Erta Ale. Rocks range in composition from basalt to rhyolite. Barrat and others found that two mantle sources were tapped for the basalts: one similar in composition to the source for mid-ocean ridge basalts (called MORB by geochemists) and one similar in composition to the source for ocean-island basalts (called OIB). Their data did not show a significant contribution of sialic material from the continental crust. The silica-rich volcanics are derived from fractional crystallization of basaltic magmas.
If your looking to travel to Ethiopia and are willing to spend a holiday in Ethiopia, you're in luck. There are many tour and travel agencies in Ethiopia that provide family holiday services in Ethiopia. These ethiopian holiday services are different for one travel agency to another. Some tour operators take their guests to the northern part of Ethiopia which has many historically significant cities such as Axum, Gonder, Bahir Dar. Others take their clients to the southern part of Ethiopia which is suitable for people who enjoy bird watching and lodging in cities such as Arba Minch and Hawassa.
The Danakil Depression
is a desert basin which lies in the Danakil Desert in north-eastern
Ethiopia and southern Eritrea. It belongs to the homeland of the Afar people. It lies up to 100 m below sea level as a result of tectonic
activity caused by plate movements. The presence of many volcanoes in
the region, including Erta Ale and the Dabbahu Volcano in the middle of the depression, also finds its cause in these plate movements.

Nowadays, Sim cards are becoming very cheap and you can buy them in normal shops and stores. In the old days, you only found Sim cards in the Ethiopian Telecommunication offices, which is currently called Ethio Telecom. Sim cards are more available than they used to be and they are cheaper than ever.
So, why not buy a Sim card? Why do you need to rent a sim card or evdo in addis ababa, ethiopia?
