A continent is slowly splitting in two: the crack extends 3.500 kilometers and opens the way to a new sea

The Earth's surface is in a state of constant motion and change. Around 138 million years ago, South America and Africa were connected. If you observe a globe closely, you'll notice how their coastlines align like puzzle pieces. Similarly, a recent geological process is causing the African continent to split into two.

This rift, identified approximately six years ago, has since been extensively studied to determine its causes and potential impacts. Known as the East African Rift, it stretches 3,500 kilometers from the Red Sea to Mozambique, according to the Geological Society of London.

Why Africa is splitting in two?

Thirty-five million years ago, the East African rift started forming. Lucía Pérez Díaz, a researcher specializing in fault dynamics, noted in an article for The Conversation that this rupture is due to a horizontal extension force in the lithosphere. This force caused the Earth's outer layer to stretch, thin, and eventually break, resulting in the formation of the Rift Valley.

According to the expert, fissures represent the initial phase of a continental breakup and, if successful, can lead to the creation of a new ocean basin. This process is accompanied by other geological phenomena, such as volcanic activity and earthquakes.

She also mentions that beneath the major crack, a substantial column of mantle rises, which continues to weaken and fracture the lithosphere. This occurrence has been documented in geophysical studies and is referred to as the "African superwave".

When will Africa be completely divided?

According to Perez Diaz, it will take several tens of millions of years for Africa to completely split apart.

Cynthia Ebinger, a geology professor, informed Live Science that there are eastern and western fissures throughout Africa, indicating that the continent is splitting in multiple directions.

Ebinger stated that the current rate of splitting is very slow, comparable to the growth of toenails, at approximately 6.35 millimeters per year.

However, researchers believe that the rate of splitting could either accelerate or halt, depending on geological forces.

Ken Macdonald, an Earth scientist, explained to LiveScience that it is uncertain whether the splitting will continue at its current rate, eventually forming an ocean basin like the Red Sea, and potentially a smaller version of the Atlantic Ocean. Alternatively, it might speed up or stop altogether.

Regardless, the rift is present and will continue to expand as long as the dynamics of the deep Earth permit it.

Which countries does the African Rift pass through?

The Great Rift spans across the following countries: Mozambique, Malawi, Tanzania, Zambia, Burundi, Rwanda, Uganda, the Democratic Republic of the Congo (DRC), Kenya, and Ethiopia.

Another continent with a fissure

The Himalayan peaks, reaching heights of 8,850 meters above sea level, form the highest mountain range on Earth. This region marks the ongoing collision between the Indian and Eurasian tectonic plates, a process that has been occurring for 600 million years. Geologists have indicated that Tibet, located northwest of these mountains, is at risk of splitting in two.

A study published in the journal Science suggests that the Indian plate is "delaminating" as it moves beneath the Eurasian plate. The friction seems to intensify with each passing century, potentially causing the upper section to break off. Currently, a vertical fissure has been observed.
