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. 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 Poás Volcano.

One year later, the first effective test for syphilis, the Wassermann test, was developed. Although it had some false positive results, it was a major advance in the detection and prevention of syphilis. By allowing testing before the acute symptoms of the disease had developed, this test allowed the prevention of transmission of syphilis to others, even though it did not provide a cure for those infected. In the 1930s the Hinton test, developed by William Augustus Hinton, and based on flocculation, was shown to have fewer false positive reactions than the Wassermann test. Both of these early tests have been superseded by newer analytical methods.
