Fonctionnement des systèmes d'ASP. Les tremblements de terre libèrent une énergie qui traverse la Terre sous forme d'ondes sismiques. Des capteurs sismiques détectent la première énergie émise par un tremblement de terre, les ondes P [primaires] qui causent rarement des dommages. Les capteurs transmettent cette information à des centres de données où un ordinateur calcule la localisation et la magnitude du tremblement de terre, ainsi que les tremblements attendus dans la région.
