July 2014 Mission

Our mission is monitoring and keep a complete registry of all the earthquakes that occurs in Chile to deliver, at any time and at any moment, the most complete information to the goverment agencies, authorities and to the people that design and improve seismic norms that guide the construction of buildings and structures in our land. To accomplish our mission we must maintain a large, robust and reliable network of seismological stations in the whole country. Seismicity
