The
STA/LTA trigger algorithm is well suited to cope with fluctuations of natural seismic noise,
which are slow in nature. It is less effective in situations where manmade or natural seismic
noise of a bursting or spiky nature (e.g. wind gusts) is present. At sites with high, irregular
seismic noise, the STA/LTA trigger usually does not function well, meaning there are too
many false triggers.
