Text: The Volcanological and Seismological Observatory of Costa Rica (OVSICORI) at the National University of Costa Rica, in Spanish Observatorio Vulcanologico y Sismologico de Costa Rica (OVSICORI) have a dedicated team in charge of researching and monitoring the volcanoes, earthquakes, and other tectonic processes in the Central America Volcanic Arc. 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. Poas Volcano is an active 2,708-metre (8,885 ft) stratovolcano located in central Costa Rica; it has erupted 39 times since 1828. On February 25, 2014, a webcam from the OVSICORI captured the moment a dark cloud exploded about 1,000 feet (300 m) in the air from a massive crater of the Poas Volcano.
