Hazard: attenuation and coda Q
Ground Motion Prediction Equations or Attenuation relations play an important role in the hazard assessment.
In general these are empirical equations that predict the ground motion, usually acceleration or velocity,
given the magnitude of, and the distance to a given earthquake. Since the Netherlands is a low seismicity country,
direct measurements of peak accelerations or peak velocities for damaging events are rare.
A recent evaluation of ground motions due to induced shallow events provide some insight in the attenuation of
ground motion in The Netherlands due to earthquakes, and specifically, due to shallow (induced) events.
