A recent study by the Southern University of Science and Technology in Shenzhen, China, suggests an alternative hypothesis to explain the Al Haouz earthquake in Morocco on September 8, 2023. According to the researchers, hot, molten rock rising from deep within the Earth, known as mantle dynamics, could be a cause. Morocco Earthquake
The earthquake that struck the High Atlas Mountains in Morocco on September 8, 2023, may have been triggered by movements of hot, molten rock deep within the Earth, according to a recent study by scientists at the Southern University of Science and Technology in Shenzhen, China.
The researchers consider the quake, which killed almost 3,000 people and affected 2.8 million, to be highly unusual, and the strongest in the region since 1960. Big earthquakes frequently happen at the meeting point of tectonic plates, but this is not the case for the Al Haouz earthquake.
What’s more, most of Morocco’s seismic activity occurs near the Rif mountains, where the African and Eurasian plates converge. Those close to the High Atlas Mountains, where the natural disaster occurred in 2023, converge at a rate of only around 1 millimetre per year. Morocco Earthquake
Upwelling of water from the earth’s mantle
The Middle Atlas, High Atlas, and AntiAtlas ranges are formed by “mantle upwelling processs,” according to the study.In other words, the Al Haouz earthquake occurred as a result of upwelling pushing on the fault, causing it to slip. Researchers studied the earthquake by integrating geodetic and seismic data, to reveal where it started and how it moved underground. Morocco Earthquake
The study shows that the movement began at a depth of around 26 kilometers, on a line known as the Tizi n’Test fault system. “The Moroccan High Atlas earthquake of 2023, a magnitude 6.8 seismic event, constitutes a major case for understanding intraplate seismicity under the influence of mantle uplift,” the study reads.”
Furthermore, it explains that this “rare lower crustal earthquake, far from plate boundaries and in a region of low convergence rate, challenges long-standing paradigms of seismic risk”.
The study concludes that such findings help to understand and improve earthquake predictions, especially in regions that do not generally experience significant seismic activity. The Middle Atlas, High Atlas, and AntiAtlas ranges are formed by “mantle upwelling processes,” according to the study.
