FIV3

 

 

 

FIV3, referred to the Filtered Incremental Velocity, is a period‐dependent intensity measure and computed as the sum of the three largest incremental velocities obtained from a low‐pass filtered ground acceleration time series. In QuakeManager, FIV3 is calculated under the NGA periods.

 

Figure below presents the FIV3 of the A-STU (RSN 292) record with respect to the NGA periods.
