The Volcanological Institute of the Canary Islands (Involcán) has attributed the rumbling that was felt in several parts of Gran Canaria this Wednesday to the impact of a shock wave caused by a "natural or artificial" object moving through the atmosphere at supersonic speed, probably an aircraft or the remains of a fireball.The Canary Islands Seismic Network, operated by Involcán, recorded a seismic signal in Gran Canaria at 4:35 p.m. caused by the passage of a strong sound wave across the island. "The preliminary analysis of the seismograms shows a shape consistent with an N-wave, generated by the impact on the ground of a shock wave caused by a natural or artificial object moving through the atmosphere at supersonic speed," added Involcán. At 3:40 p.m., a loud rumble reminiscent of an explosion was heard in several parts of Gran Canaria, especially in the capital, shaking windows and blinds."The preliminary analysis of the seismograms shows a shape consistent with an N-wave, generated by the impact on the ground of a shock wave caused by a natural or artificial object moving through the atmosphere at supersonic speed," added Involcán. At 3:40 p.m., a loud rumble reminiscent of an explosion was heard in several parts of Gran Canaria, especially in the capital, shaking windows and blinds. The Emergency Coordination Center of the Government of the Canary Islands (112) received up to 40 calls informing about the incident. "The emergency number 112 has received about 40 calls from different areas of Gran Canaria, reporting a loud bang. None of them have reported any damage and there have been no relevant incidents on the island that could be related," the social media profiles state. The seismic stations of the National Geographic Institute (IGN) also recorded what happened, but one of their seismologists, Itahiza Domínguez, ruled out through his Twitter account that it was an earthquake. https://www.diariodecanarias.es/noticia/un-avi%C3%B3n-supers%C3%B3nico-o-restos-de-un-b%C3%B3lido-candidatos-detr%C3%A1s-del-estruendo-en-gran-canaria#:~:text=El%20Instituto%20Volcanol%C3%B3gico%20de%20Canarias%20%28Involc%C3%A1n%29%20ha%20achacado,un%20avi%C3%B3n%20o%20los%20restos%20de%20un%20b%C3%B3lido.
