Harmonic Tremors was created on 2007-01-26.
Harmonic tremors are typically detected using seismographs, which are sensitive instruments that measure ground vibrations. These tremors indicate moving magma beneath the Earth's surface, as they produce a continuous, rhythmic pattern of seismic waves. The presence of harmonic tremors often suggests that magma is accumulating and moving through underground channels, which can be a precursor to volcanic activity.
Tremors - roller coaster - was created in 1999.
The City Harmonic was created in 2006.
Spherical Harmonic was created in 2001-12.
Oxford Harmonic Society was created in 1921.
Nottingham Harmonic Society was created in 1846.
There are two types of magmatic earthquake: those cause by the breaking of rock and harmonic tremors. Those caused by the breaking of rock taper off more quickly than normal tectonic earthquakes. Harmonic tremor are caused by the movement of magma through a conduit. These are notable for having a consistent frequency and intensity.
"Tremors" (1990) "Tremors II: Aftershocks" (1996) "Tremors 3: Back to Perfection" (2001) "Tremors 4: The Legend Begins" (2004) There was also a 2003 television series.
It reduces the amount of harmonic drone created by the exhaust noise.
They are called aftershocks, or tremors.
