| Harmonic tremor | Geological | Continuous rhythmic earthquakes in the Earth's upper lithosphere that can be detected by seismographs. Harmonic tremors often precede or accompany volcanic eruptions. (Teacher's Packet)* A continuous release of seismic energy typically associated with the underground movement of magma. It contrasts distinctly with the sudden release and rapid decrease of seismic energy associated with the more common type of earthquake caused by slippage along a fault. (Foxworthy and Hill, 1982).

| Harmonic tremor | Geology | 1: 1) Continuous rhythmic earthquakes in the Earth's upper lithosphere that can be detected by seimographs. Harmonic tremors often precede or accompany volcanic eruptions. 2) A continuous release of seismic energy typically associated with the underground movement of magma. It contrasts distinctly with the sudden release and rapid decrease of seismic energy associated with the more common type of earthquake caused by slippage along a fault. (Foxworthy and Hill, 1982). 3) Harmonic tremor, which is a long-lasting, very rhythmic signal whose origin is not well understood but which is often associated with active volcanoes. (Brantley and Topinka, 1984). (references) | |
