[en] Full text: IS02 infrasound station is located 100 km from Ushuaia city, Argentina. It became operational in April 2005, but due to flooding of the vaults all of them were reinforced in January 2006. The station was certified in August 2006. After two years new problems with water filtration appeared at the station, making it extremely necessary to update its infrastructure. From the station operator's point of view, the new design of the station sites proved to be successful since no water problems appeared in the vaults and pipes of all of them. The graphs show the improvement in the signal in one of the arrays before and after the 2010 infrastructure upgrade. The efforts made by PTS and Station Operator (ARN) allowed the achievement of the planned goal, resulting in a better behavior of the station since the works described in this poster were carried out.
