The Vienna-based Comprehensive Nuclear Test Ban Treaty Organization provided in the last hours new information regarding the explosion that was recorded in the area in which the ARA San Juan submarine went missing 14 days ago, along with its 44 crew members, three hours after establishing communication for the last time.
The organization’s executive director, Lassina Zerbo, announced in his Twitter account that they managed to reduce the area where the explosion could have taken place. As a result of this, the search patrols could circumscribe their operations to that area.

This organization provided one of the two reports that led the Argentine government to confirm on Thursday November 29th that the aforementioned explosion had been registered – while the other one came from the government of the United States along with “agencies from other countries”.
The first recording came from one of the several several seismic hydroacoustic stations the organization has in place to make sure nuclear tests are not conducted anywhere. The second, more precise one, was registered through the measurements of two seismic stations, which complement the information the hydroacoustic ones provide.
According to the tweet’s photo, the search radius is near the end of the Argentine economic exclusive zone and the beginning of the continental slope. This would mean that – should the explosion have come from the submarine – the possibilities the ARA San Juan fell to a depth over 600 meters are larger. If this was the case, its retrieval would became impossible, as the rescue mini submarine provided by the US Navy – the most modern in the world – can only operate up to that depth.
