4.4 Ethiopian Quake

The Horn of Africa is breaking apart a new ocean is been made a Magnitude 4.8 just hit the region as a recent manifestation risk to dams in the valley

Geologists working in the remote Afar region of Ethiopia say the ocean will eventually split the African continent in two, though it will take about 10 million years seems it is that end of time now we are in. As Many researchers are  described the events as “truly incredible”. Used to understanding changes in the planet on timescales of millions of years  have seen amazing changes in Afar in the past five years, where the continent is cracking open, quite literally underneath our feet. In 2005, a 60km long stretch of the earth opened up to a width of eight metres over a period of just ten days. Hot, molten rock from deep within the Earth is trickling to the surface and creating the split. Underground and  eruptions are still continuing and, ultimately, the horn of Africa will fall away and a new ocean will form. Thus producing risk in the dams being constructed in the  Ethiopian  side of the valley

“The East African Rift System (EARS) is one the geologic wonders of the world, a place where the earth’s tectonic forces are presently trying to create new plates by splitting apart old ones. In simple terms, a rift can be thought of as a fracture in the earth’s surface that widens over time, or more technically, as an elongate basin bounded by opposed steeply dipping normal faults. Geologists are still debating exactly how rifting comes about, but the process is so well displayed in East Africa (Ethiopia-Kenya-Uganda-Tanzania) that geologists have attached a name to the new plate-to-be; the Nubian Plate makes up most of Africa, while the smaller plate that is pulling away has been named the Somalian Plate (Figure 1). These two plates are moving away form each other and also away from the Arabian plate to the north. The point where these three plates meet in the Afar region of Ethiopia forms what is called a triple-junction. However, all the rifting in East Africa is not confined to the Horn of Africa; there is a lot of rifting activity further south as well, extending into Kenya and Tanzania and Great Lakes region of Africa. The purpose of this paper is to discuss the general geology of these rifts are and highlight the geologic processes involved in their formation.”
