The Instituto Geográfico Nacional recorded an earthquake on 26 August 2026 in the Atlantic off the north coast of Tenerife . The main shock was located at 17:37; according to the official coordinates, the epicentre was at 28.7704 degrees north and 16.3439 degrees west. The preliminary estimate of magnitude 3.6 and a depth of 34 kilometres indicate an offshore event of moderate low magnitude.
According to the agency’s classification, the earthquake was felt weakly by some members of the public (intensity II). So far, there are no confirmed reports of injury or property damage. The Instituto Geográfico Nacional’s figures are preliminary and may be revised after routine data checks.
The Canary Islands are regularly affected by minor seismic activity. Causes include both tectonic stresses and volcanic processes in the oceanic lithosphere. Events in the Atlántico-Canarias region with low magnitudes frequently occur offshore and are only weakly felt on land, particularly when they are farther from the coast or occur at greater depth. The current magnitude 3.6 earthquake fits this pattern. Based on current knowledge, a single event of this size does not pose an immediate threat.
The IGN catalogue lists further minor tremors in the area that day. Seismological services are monitoring developments continuously. Should a sequence with increasing energy or changed activity emerge, the authorities would provide information and, if necessary, issue guidance to the public. The current data give no reason for special measures.
Two measures are central to interpreting reports of this kind: the energy released (magnitude) and the intensity felt locally. While a magnitude of 3.6 provides an objective measure of the strength of the source, the reported intensity depends heavily on distance, depth, ground conditions and building characteristics. With an earthquake 34 kilometres deep in the Atlantic, it is usual for it to be felt only weakly on land and for structural damage to be avoided.
The official measurements and location details are from the Instituto Geográfico Nacional. New assessments, such as revised magnitude or intensity figures, will be added to the agency’s ongoing updates.
