NEW UPDATES Why Africa Is Splitting Into Two!
In September 2005, the ground in northeast Ethiopia shattered into a thousand pieces over the course of a few days amid a flurry of volcanic eruptions and a large number of earthquakes. In the Afar Depression, a desolate spit of desert where summer temperatures can soar as high as 120 degrees, a bubble of molten rock had been bubbling beneath the Earth for millions of years. The ground was split in two and a fissure about 40 miles long and up to 25 feet broad was created when it finally reached the surface.
According to Cynthia Ebinger, a geologist at Tulane University, "We had never seen something like this." On the seafloor, this kind of activity is common, but this is the first instance on land that is known of.
The Dabbahu Fissure, as the rift that erupted in 2005 came to be known, is not the first geological event to shake the Afar, an isolated area dotted with geysers, gas vents, hot springs, volcanoes, and one of the few lava lakes in the world. The Arabian, Nubian, and Somali plates are cradled in a Y-shape by the Afar Triple Junction, a hotspot for Earth scientists. These plates are spreading apart at a rate similar to how fast your fingernail grows, and activities beneath them are producing the intense heat and energy that are responsible for the distinctive geophysical features the area is known for.
Today, the Dabbahu Fissure is the most prominent of those features. It is presently believed by scientists that the first continental fracture since Pangea will take place along this rift and that, in a few million years or so, Africa may span two continents, allowing the Earth to introduce its newest ocean.
What exactly is the East African Rift System?
The north-south East African Rift System (or EARS), one of the world's greatest geological wonders, is actually a network of rifts and valleys brought on by the splitting of the earth's crust. The Eastern Rift Valley, which stretches from Jordan to the coast of Mozambique, is one of the two branches of EARS, which has been in the making for roughly 25 million years. Meanwhile, the Western Rift Valley, which spans from Uganda to Mozambique, is home to some of the world's deepest lakes.
However, the Afar Depression, which has the highest rates of magma production and the most active volcanoes in the area, is the most dramatic of all the terrain that is shifting inside EARS. Under the Depression, a mantle plume of magma had grown over time, forcing hot rocks toward the surface like globs of oil in a lava lamp. Magma eventually began to push up into the fissures between those rocks as a result of intense pressure, causing Dabbahu Fissure to rupture in 2005.
According to Ebinger, the pressure was so intense that the plates separated by as much as 25 feet, accomplishing 400 years of separation in a matter of days. One of the experts who was using satellite data to estimate the new rift was certain that his calculations had gone wrong because it was such a large figure.
What causes rifting to occur?
The lithosphere will stretch and thin when it is subjected to a horizontal extensional force. It will eventually break, creating a valley known as a rift.
Volcanism and seismic activity are surface manifestations of this process that can be seen along the rift valley. If successful, rifts, which are the first step of a continental break-up, can result in the formation of a new ocean basin. The South Atlantic Ocean, which formed when South America and Africa split apart some 138 million years ago, is an example of a location on Earth where this has occurred. Have you ever noticed how their coastlines fit together like parts of a puzzle?
Observing the Creation of an Ocean
After the 2005 incident, Ebinger was in Ethiopia working with scientists from all around the world to quickly deploy geophysical instruments. Within weeks of the disaster, Ebinger was on a plane.
