ISMD is the new INGV strong-motion data web portal that provides soon after the earthquake (ML ≥ 3.0) occurrence both waveforms and related metadata.

Soon after the comunication of the event occurrence (UTM origin time, hypocentral coordinates and local magnitude) provided by the Italian National Earthquake Center of INGV, the ISMD automatic system downloads 5 minutes of signals starting from the event origin time.
