In the context of the permanent seismic surveillance network managed by the Vesuvius Observatory, a remote control system associated with High-Availability (HA) microclusters has been implemented. It satisfies the operational need to reduce the downtime of data acquisition systems in case of malfunctioning of the HA cluster, drastically reducing the need to have an on field operator for resolution. The present work, therefore, aims at providing a technical description of the High-Availability (HA) system in use at the seismic station of Forio Punta Imperatore in the island of Ischia (identification code: IFOR) and of the related remote control system that has been implemented, named Remote Communication and Start/Stop System (RC3S).
