The strongmotion database of the Centro Sismológico Nacional

Abstract

Since its creation in 2012, the Centro Sismológico Nacional (National Seismological Center) of the
Universidad de Chile has managed the seismological networks that monitor seismicity in Chile. Part of it is
composed of more than 400 accelerometers, some of them recording continuously and others with a trigger.
From this extensive network, records have been collected for more than 3000 Chilean events. These records present
an invaluable tool for the knowledge of the seismicity in Chile and the behavior of the soils in Chilean cities
and towns. This work shows some tools for the use of this extensive database, together with some features that
facilitate its use. This opens a door of access to the entire community to nourish by these data.
