The Center for Study of Short-lived Phenomena (CSLP) was established under the direction of Robert A. Citron in order to study rare or infrequent natural phenomena such as volcanic eruptions, earthquakes, meteorite falls, the birth of new islands, and other sudden changes in biological and ecological systems. Located at the Smithsonian Astrophysical Observatory, the Center existed from 1968 to 1975. After some restructuring CSLP became the Scientific Event Alert Network (SEAN) in 1975 with the purpose of alerting scientists as soon as possible to selected geophysical, biological, astronomical, and athropological events taking place anywhere on Earth and to collect and store event information in a central repository for research purposes. SEAN went on to become the Global Volcanism Program, which is based at the National Museum of Natural History.
