Shallow earthquake in Gulf of Aden; minimal impact expected in Somalia and Yemen

 

A magnitude 5.6 earthquake occurred in the Gulf of Aden at 10:31 a.m. EAT, December 5. The epicentre was identified 149 kilometres north-northwest of Las Khorey, Somalia and generated tremors felt across parts of northern Somalia and southern Yemen. The quake, originating at a shallow depth of 10 kilometres, raises concerns over its possible effects.

The US Geological Survey (USGS) has confirmed the quake's parameters and is monitoring the situation closely. Despite the quake's magnitude, initial assessments suggest a minimal impact on life and property. Detailed surveys, particularly in remote regions, are underway to evaluate any potential damage.

Approximately 0.9 million people are estimated to have felt the earthquake. Light shaking, the most significant effect of the quake, was likely experienced by around 200 individuals. The tremor was also felt in Yemen, with an estimated 580,000 people exposed to shaking.

The USGS has categorized the risk of fatalities and economic loss as low, projecting a 65% likelihood of either no casualties or minimal economic damage not exceeding 1 million USD. The probability of the number of fatalities not surpassing 10 is also high, at 96%.

Seismologists note that the released seismic energy of the quake is equivalent to about 3788 tons of TNT. The nearest volcano, Harra es-Sawâd in southern Yemen, is 203 kilometres from the quake's epicentre. Weather at the time of the earthquake was reported as mild, with scattered clouds and temperatures around 26.7°C.

Local authorities in the affected regions are on alert for potential aftershocks. They advise residents to adhere to safety guidelines and stay updated on further developments.
