In 1984, the OVSICORI-A initiated the operation of a seismographic network designed to monitor seismic and volcanic activity throughout the national territory. Currently, the seismographic network has an analog and a digital registration system. The latter enables online analysis of seismic signals, allowing to expedite the analysis of signals and the study using modern computerized methods. Poás Volcano is an active 2,708-metre (8,885 ft) stratovolcano located in central Costa Rica; it has erupted 39 times since 1828.
