classic_sta_lta_py(a, nsta, nlta)[source]

Computes the standard STA/LTA from a given input array a. The length of the STA is given by nsta in samples, respectively is the length of the LTA given by nlta in samples. Written in Python.


There exists a faster version of this trigger wrapped in C called classic_sta_lta() in this module!

  • a (NumPy ndarray) Seismic Trace
  • nsta (int) Length of short time average window in samples
  • nlta (int) Length of long time average window in samples
Return type:

NumPy ndarray


Characteristic function of classic STA/LTA
