| Harmonic tremor is a sustained release of seismic energy typically associated with the underground movement or venting of magma and/or volcanic gases. Being a long-duration continuous signal from a temporally extended source, volcanic tremor contrasts distinctly with transient sources of seismic radiation, such as are typically associated with earthquakes and explosions....... this might explain it a little better:Harmonic tremor describes a long-duration release of seismic energy with distinct spectral (harmonic) lines that often precedes or accompanies volcanic eruptions... |
